The ACS light came on the bunk panel APU CONTROL UNIT SO I TOOK IT TO A THERMO KING SHOP. THE TECH SAID IT WAS THE BUNK EXTERNAL FAN 20AMP FUSE HE REPLACED IT WITH A 25AMP FUSE DUE TO THE FAN UNIT AFTER TIME STARTS PULLING MORE AMPS. - Авто та транспорт
I'm a technician for a very BIG and WELL known company.. saved my ass lmao. Wasn't this peticular fuse but you definitely pointed me in the right direction 🤣🤣 thank you so much!!!
I’m a mechanic for mail trucking company. You saved my ass lmao we never seen an acs code before. I checked the fuses and it was the 7.5 amp (7CL) thank you so much for the info.
You saved me money brother Thnks 🙏🙏🙏🙏🙏🙏🙏👍👍👍👍
Here's my problem, SOLVED. Volvo 780 '16
yelow trialngle came on after starting apu, noticed its not blowing cold as it used to.
After 5min apu shuts off, red triangle came on, snowflake flashing and green acs on.
Did some research, you can download thermo king manual, for those who are wondering ACS is ac related problem, ENG-engine and ALT-alternator/battery.
My problem was a fuse, in 780 volvo they are located under passanger side bunk, black box with big fuse scheme, you have to unscrew 4 screws and there they are.
Started checking from top, 4th fuse-7cf F11 20A, blown madafaka! Replaced it with same 20A, I see some people recommend 25A instead but I'll keep 20A in it and we'll see how long it holds, I'll post here if anything happens.
So glad I wasn't lazy to look this up on UA-cam especially cause I serviced it 2 weeks ago, 350$!
I swear these things are so temperamental!
It will blow again. Thermo king's solution is to upgrade to the 25a
Thank you brother!!! So simple most would look past it... saved me a trip to mechanic! Thanks for posting!! Fuse wasn't even blown, just not conducting enough. Replaced w/ 25amp works great!
Thank you for letting me know this, you saved me a trip to Thermo King! I checked my fuses, and sure enough the 20amp was blown. I replaced it and it's running great!
where is the fuse box located, I have same issue
@@abdideeqm6713 This issue just started for me I need a fix also I have flashing light but not the yellow light
Dude, you saved my night from having to sleep in 90F heat! Thanks for posting!
@Rick C some of these truck will.not idle
Owner operator...Thank You so much lead me to my problem. However, my fuse F11 (7CF) was blown. 2015 Thermoking APU....so check the F11 (7CF) or as this gentleman stated check F12 (FAN1)...same code hazard with ACS....My fuse blew running overnight in rainstorm....also turning my heater on late night may caused my fuse to blow as well... may be the reason for the F11 and not the F12 blown. Thanks again.
Thank you for posting this. None of the fuses I checked appeared to be blown, but I switches the 20A just in case, and it’s working…for now. Will update if anything goes wrong.
-2020 Kenworth, but same Thermoking.
You just saved my life with this video...thank you so very much!
Thanks u Sr, I had the same problem, and is now fixed, thanks u Sr...2015 freightliner 👍👍💪
Thanks for posting this video, I had the same issue and checked and sure enough that 20amp fuse was blown. Replaced it and now it works again, thanks brother!
Where is this 20 amp located?
Thank you man. Priceless in this heat.
Hey man I wanna say thanks! had the same problem.... It was the fuse, mine though wasnt on F11 it was where it says 7CF..... Think the CF stands for condenser fan..... Anyways you saved me from outright buying the fan.... Many Many Thanks!
Yup! 7.5 Amp fuse in the box...
Fixed my dead APU... Thank you- cool air again :)
You saved me tonight ! I had this same problem and luckily I looked on UA-cam and you had this video
Where is the fuse box for this
Thanks for the info.. a fuse the whole time been otr with no APU AC for two weeks... You got my thumbs up 👍
Where is this fuse located at?
Thanks ...After adding Freon, and a full PM sevice i had the same problem..And it was the same fuse you said it was..I appreciate it..
Where do i find this fuse at?
Thank you for the effort of creating this.I hope mine is similar.
Thank you for the video I was having the same problem went into the fuel box found the fuse that was broke put a new one in and it’s working perfect now.....
Had same problem with mine. I'm with everyone else thanks for posting video.
Having the same issue thanks! Same company as well. Stay safe driver!
I just had the same problem but the driver broke the fan and was throwing those lights. Thank you for the video
As mentioned earlier, I installed a 25 amp in place of the 20 amp in the 7CF slot. The unit ran fine for another 30 hours then got the warning again. Fuse OK, then found that the condenser fan was seized. Need to replace. Looks like the fan bearings were on their way out causing additional current draw. I will replace the fan then reinstall the original 20 amp fuse.
Thank you for info that fixed my problem
Thank you soo much man , mine is also has the same problem and I’ll fix by myself now .
Thank you so much! Saved me a hot one mate.
Just wanna say thank you its 75 here in Texas this really helped tonight
Thnks thnks thnks alot ... I had a same problem a while ....it worked when I changed the fuse
(( the fuse box is located under the bunk if you have freightliner and the all directions are on the box ))
By the way
I didn't have a spare fuse when I was watching your video so I used the HTR fuse since I'm in summer and don't need the heater!
Man thnks again that really helped a lot.
Thank you so much, sir. God bless you. I did have exact the same problem.
Worked for me. Thanks a lot.
Thanks a lot sir you save my time my money
Saved my bacon, 5 minute fix. Mine was the 3rd 20 amp from the bottom left. 2017 truck. THANKS!!!
That was exactly my problem. I followed your instructions, replaced the fuse and all resolved.
Thank you.
Where the fuse located
Where is that fuse
I found it and fixed, but I replaced 2 of those 20 amp fuses with a 25 amp fuse thnxs 🤗
Just got my AP unit working after having it for about 5 months never really checked it out get out so I pulled over today cut this cut the switch on turn the hoses on filled my free on up a little bit more rain for a couple of minutes love minutes will actually a couple of hours until I started getting hot so I saw the! Reset it now I'm gonna see how long it takes for that light to come back on . But I will take your advice and check those fuses thanks for the video be safe out there driver
Well here's another thank you, you are a lifesaver message 😅
Great job 👏
I had the yellow triangle and then run for 20 minutes or so. I'd restart the APU and it would runnfornb20 minutes and shut off. I was told by a thermo king dealer that i needed a new a/c compressor. Or freon is low. I let it go for some time. A friend of mine worked for that thermo king. And quit. I asked him what's the deal. He said 90% of the time, it's a ground or loose connection issue. I spent couple hours taking connectors apart, cleaning them, and reconnecting.
After all connection cleaning, alternator connections, and major ground to frame, it fires up and works just fine
Thank you 🙏🏾
I appreciate this video man just unfortunately doesn't seem to be my problem. After watching this checked my fuses and all seem fine. Problem persists.
Edit: After reading through the comments I checked the main fan outside, and yeah that baby doesn't move a muscle. So guess its something fan related but not the fuse... I'm just a dumb company driver but either way out here melting in GA/TN last 4 days so was hoping to find/fix the problem myself.
Thank you so much
APU is going to be the reason why I quit OTR and go local....... Winter the heater always goes out, summer the fucking a/c breaks every other damn week. I hate this shit. So then I can't sleep. Sweating profusely, or freezing my sack off!!! 😡🤬 Sorry for cursing but this shit sucks. They say truck is supposed to idle if drops or raises to a certain temperature but of course it doesn't idle
I had the yellow triangle and then run for 20 minutes or so. Then red triangle ut would turn off. I'd restart the APU and it would run for about 20 minutes and shut off. I was told by a thermo king dealer that i needed a new a/c compressor. Or freon is low. I let it go for some time. A friend of mine worked for that thermo king. And quit. I asked him what's the deal.

Thanks for the video! It helped me out!
That is what mine was doing. Thanks
These things have a mind of there own
Im getting the same code, mine comes on and runs about 10-15 mins, doesnt blow cold then gives orange triangle then red triangle when it cuts off. The fan on the back of my sleeper is working. I havent checked the fuses but with it working i feel like the fuse has to be good. Im fixing to be home im gonna pull it to the barn and check it out. The shop left the bottom covor off the apu for about 6 momths after they serviced it and dirt and all kind of stuff got up in there and is all over everything. Im almost wondering if that dirt isnt stopping up my condenser and its over heating and cutting off. Ill keep yall posted.
Got my apu serviced because my dispatcher told me to. Now I keep getting that same warning. Went home for the 4th of July and came back to my truck saying load shed. It's literally 100+ degrees in the truck everywhere I go and my company has the engine shut down on something pass 120°F because it still shuts off when it's reading that high
Thank you for this video and saving my night brother.
Under normal circumstances, you would never ever upgrade the fuse... except this time. Its not the fuse is old, but that fan on initial start requires more than 20a. After starts it requires less than 20a. So why the heck do they just start with a 25a fuse I dont know. Technically speaking the wire should also be upgraded to handle the momentarily requirement for the extra start up "juice."
Any other suggestions? My fans are turning but having the same issue.
I turned off the main unit for 5 minutes and that cleared the light !
Mine was doing to same thing I replaced the fuse but that didn't stop it. Ended up being the fan on the condenser wasn't cooling well enough so it was.causing high head pressure and shutting the unit down. Ended up needing the replace the fan and it resolved the issue for me.
Having the same problem, TK mechanic came out to me and check and double checked everything, no Freon leak, it’s full, no codes popped up, we let it run and it didn’t act up of course, so I don’t know what is wrong, I tried everything I can, turning it off and on and still the A/C quits but the Tri-PAC stays running.
Great video, unfortunately all my fuses are ok but clutch don’t click in so the compresor won’t work. Y checked the current on the connector and only gets 7 volts. Will keep looking, thanks for your help. My next app definitely won’t be a thermoking, they charge a lot to look or fix it at the dealer.
My tire blew out and hit my compressor. I checked all of my fuses and they're all okay just like yours. I'm thinking I need to just replace the compressor. Did that solve your issue? When the condenser fan starts up my unit shuts off and throws the ACS or AC5 code.
I have the same problem right now. But don't have the tools. Ill get everything as soon as I get to a truck stop.
Jesus, I'm going through this right now! Its 98 here in Yakima! I'm dying
STFU. I'm having this issue as well. I'm not in yakima, but I was born and raised there. Crazy coincidence.
I have a volvo vnl 670 where can i find the fuse box for my apu
In my situation F10 was burned out. Changed it and it works fine
Thank you thank you thank you! But mine was the CF fuse that was two fuses above like someone else said. It always happens when you need it most.
When I pulled the fuse I slowly put the flashlight behind it and prayed.
Where the fuse located
@@ChasingAlex88 The fuses are located in the control box. My box is just inside the side box on the passenger side
The crap we put up with.
I had a new alternator installed 2 months ago. But today i had an alt red light come on. Any idea what it can be?
I had the same problem but it was a sensor that would keep the apu on until it caused the alternator to fail. the technician told me the sensor tells the alternator that my batteries were in need of voltage but it never shut the apu off.
If fan fuse not blown and condenser fan not working check 7CF fuse above it that was my problem.
Replaced 20 amp fuse in the 7CF slot (condenser fan). After 20 hrs of running, the fuse blew again. Replaced that with a 25 amp and initially running well.
Kevin Hegeman I check all my fuse is okay 1 minuets or 2 minuets I see yellow light
@@nonaxariis661 does the unit turn red and shut down after a while? Or keep running with yellow triangle.
No red ,,,, keep running yellow triangle
If the unit only show yellow triangle, you can continue to use it, but get it checked at Thermal King at your earliest convenience. This recommendation was taken from the tripac manual.
Thanks I solve problem so far so good
I got same dam issue please I hope is that because thermo king is 150hr
My a/c compressor stays on all the time even when I lower the fan and temperature in the cap, it get really cold so I have to turn off the apu. Does anyone now why the compressor stays on??
Watching now bc mines doing the exact same thing and I'm fucking HOT. STAYING TUNED
I already checked APU OIL, COOLANT and Fuses and seems to be ok but on screen says PUMP. Any idea ?
@@mentalamusementpark they did the service and the guy fixed some leaks , replace new compressor and charged me 1125 dlls and did Not work. He said need to replace the Electrical Board (1000.00 dlls) , cus is not sending energy to APU. Really don't know what to do.
Add me to the list bud, I owe you a beer or drink of your choice! Thanks!!
I'm getting that same triangle light but not ACS.
I'm going to try that right now
My fuses are all good though, none blowed.
My rear fan not working though
What does it mean when you get the triangle and its says "ENG"
Eng stands for engine problem, probably need service
I check all fuse it was okay and oil, can someone give me another advice, Thanks
Alternator
Just got a truck with one of these and I'm like what the heck
Mine was not the fan1 it was the 7cf the f11 20A thanks for the map to fixing it
mild man I had the same issue, f11. Glad I decided to look on here to see if there was a quick fix. I’m sure it saved a day of downtime and the aggravation of taking a 34hr in 97 degree Arizona desert
my apu is crazy, somtimes work perfect, and somtimes appear the yellow triangle, and the comdesor fan stop work,,all fuses ok,,I need help drivers please
FILL UP UR COOLANT IT SHOULD WORK FINE AGAIN FILL IT OVER MINIMUM
I have the same problem only the fuse isnt blown
@@mentalamusementpark you bet.
Did anyone ever find out what the problem was?
@@mentalamusementpark mine was the compressor on the apu
@@kevinfitts9252 mine was the compressor on the apu but no freon will give the same problem
@@AFStudiosMedia thermo king repaired it, for how much...and you also had the red triangle w cls or alt? I have alt. On this guy's vid, I couldn't tell if it was red, yellow or orange.
wheres the fuse at
Unfortunately for me fuse was good
It’s always something with these APUs
WOT
Where is this fuse located exactly?
I have a Thermo King Tri Pac on my 2022 Cascadia and it’s absolutely a total piece of crap. There’s always something wrong with, it works about 50% of the time and for 13K that’s absolutely unacceptable.
