Fantastic, to see someone who almost breaths the work he is doing, no referencing diagrams, but just quoting from the grey matter and the knowledge of knowing what should and shouldn’t be happening, plus tge practical skills of tools etc 5 stars.
Thank you very much!
Smart and efficient on using a squencer for your delay off on the fan..."Improvise, adapt, overcome” Sgt. Tom Highway- Heartbreak Ridge
You know the funniest thing about your videos is that you verbalize your thoughts! We also have those "thoughts/voices/etc" running around our melons during troubleshooting procedures - but at least we can follow YOU and YOUR thought processes!!! Another great vid....
Nicely done. A nice simple circuit for demonstration purposes. Format was also cool. You explained your thought process and gave details on why or why not to do something.....and you snuck it in on a Saturday.....🤘🤘🤘🤘🤘
Fantastic video man. Loved the non editing and taking us thorough your whole process and thinking out loud.
You made that ol piece much more reliable and simple. 👍👌
Nice working on a Bard Rick. I see lots of those where I work
Nice job thinking and making work as it should. You saved a call back because the high limit tripped because the heat strips were still warm.
Thank you!
Brings back memories of a 3 phase wall hung 460 volt heat pump on a medical imaging trailer!! Previous company had said they needed a forklift to remove it and take it to thier shop!!!!! All that was wrong was the blade had fallen off the condenser motor!!!! Fixed in a jiffy?!
I have a video of doing a imaging trailer from earlier this year
Worked on a lot of those in Rikers Island. Great video 👍🏼
🙏👍👍 thank you!
You used to get those 90340 relays with a separate time delay board that went over the coil terminals. I saw/replaced a lot of them on the old Trane and American Standard air handlers.
Interesting to hear. The Lennox Pulse used to have a time board like that.
You did a very nice job of cleaning up a big mess, not to mention the electrical hazard. I liked your verbal thouhgt process you were easy to follow. Thanks for the video.
I give this video a 12 out 10!! Great job man✌️
Thanks Randy! I haven't seen you for a while 👍👍
I'm impressed you filmed while standing on the leaning ladder. Worked on quite a few of these in rural WY I always end up dropping something into the weeds below. Hope all is well man
I love my camera mount, it works great. Thanks for watching!
Good job Rick

Wow.
I learned today!
Thanks for video
Cool 👍👍
Love your train of thought and how you went about telling us what you were doing. Awesome video Ricky.
Thanks 👍
job site trailers, that remind some, we've not been called to work on any for quite some time. got called to do a bunch of odds and ends, flooring, door closers, lights/bulbs, various repairs.
cannot say we've had any for a good handful of years now, then again all their projects nearby have dried up and they are mainly further away than we will go(short term)
That was a good video , back to basics
Awesome video ilove how you explain what you are doing
Good video brother, I always like when the diagrams are not readable or just gone , make the wiring work the simple way/your on way and try not to mess the next guy up
Thanks brother🤜🤛👍👍
Great Video. Thank you for sharing. Have a nice weekend
Thanks you too!
Good one Rick!!!!
Ah, the Bard wall hungs. Much of my education was in portable buildings served by those. Also very popular with radio tower equipment sheds.
I've done several radio towers with these. I had 17 stations all over Ohio I had to service, I brought a 55 gallon drum of water and washed them out.
Cool video Rick
great job , you can tell you have great work ethics, with knowledge
Rick, I enjoy your videos !
Pretty slick.
That was amazing repair.
That guy is amazing
Good video! Keep them rolling Rick.
I like the music too
Great job
Thanks Bill
I'd wager that unit came from the factory with some way of keeping the fan running after the heat strips shutoff ... Then Some BillyBob came along to "fix" something and tore the factory stuff out - Hey Boss, I fixed it!
🤫😉🤣🤣👍👍
Excellent fix great information 👍
Good job Rick.
Nice work Rick.
Great content, brother! You're smarter than you look 😂
Thanks, I think? 🤣
New to the channel, been in hvac awhile work on a lots of gas fired furnaces not a lot of electric heat. Question what was the time out on the sequencer you installed? Thanks for the video. Hope to watch and learn more about electric heat. Have a blessed day !
I thought it was on the box in the video? Out of memory I believe it shuts off in 45 seconds to a minute something. The on-time doesn't matter because the contactors immediate
@@HVACRSurvival great thanks, sorry I didn’t catch it if it was on the box.
If you wanted to throw a icm255 on the truck would have replaced that original time delay fan relay board or done the same thing you wanted
Another quality job brother!
Much appreciated!
I have to give you a 9,no 24v fuse.LOL.
The high voltage on the low voltage probably came from the strip/blower interlock. Those snap action stats won't close R-G on a call for heat so you would connect one leg of strip load to NC side of 90340 with the blower on Common. That way blower will run regardless if strips are called for with no G or with G. With electronic stats the interlock is a redundancy because you can usually configure the stat to control fan and provide extended run. Someone put the interlock on the wrong terminal. Ive run into this before early in my career. A 90340 relay was replaced for the blower but instead of blower being connected to common the line was connected there. The interlock was omitted because with the relay wired like this it will run strips constantly. Sometimes the interlock would bring the blower on in a lower speed as well. Kinda late but i remembered this and thought I'd share it.
I appreciate the info, I think someone misplaced the wire when the time delay relay was removed.
Can you explain relays and sequencers in some more detail sometime? They tend to confuse me especially when wired like you did in parallel. I understand that they turn on the fan or heat strips but for example in coleman furnaces where everything is controlled with two relays with like 7 wires each its hard for me to understand. Thanks for everything I really enjoy your videos. You and my boss could pass for twins 😂
That’s interesting, why don’t you email me a picture of him. At the same time can you send me a picture of the wiring diagram that you’re talking about and I’ll see if I can explain it.
"Trustess me"! 🤣 Unfortunately too many yahoos like that out there.
One thing I don't like about that style crimper is when using the insulated terminal nests the PVC sleeve while being crimped will migrate outwards and interfere between the jaws and possibly prevent a effective crush upon the barrel of the terminal. Doesn't always happen, but sometimes it does. Have seen it happen, why I went to the non-insulated crimp nests. Looked like an old W-R mercury bulb t/stat. Nice! Kinda hard to get rid of though, eh?
Depending on where you align the jaws... I place it closer to the spayed or eyelet side than the wire side.
Weird fault having 120v on w. Normally on those the red wire in the harness goes to l2 on the load side and when the heating call goes through the limit it sends the other leg of 120v to the fan motor through Nc on the relay. It’s funny those old integrated fan boards have a delay off and when you put a relay in you remove that but the ironic part is the newer bards don’t even have a delay off and use regular old fan relays as well
You're supposed to run your blower through the NC terminal on the blower relay powered by the heat contactor so that the heat contactor turns the blower on and then any stat can be used, not just a digital with a programmable blower.
I know what your saying but that ship passed a while go with all the modifications that have been done to it.
@@HVACRSurvival fair enough 🤷♂️
is that one of those baird wall mount units?
I always liked troubleshooting electrical ... Nice job as usual & very informative ... Nice stream last Saturday with the Misfits ... Thx
Awesome Eddy, I appreciate that👍👍
the old white rodgers 1f56 444
didn't you cut the common wire off the terminal strip before you checked g to c?
It was a redundant common
luckily no hornets. I can see a nest to the right inside the panel
looked like "mud daubers" mud nests, while they can sting, if provoked, they generally avoid conflict and are focused on their tasks. 😉
I had similar fan issue. I had a burnt up blower motor, and a bad fan relay on a 30 yr old Lennox heat pump. Speed tap used for electric heat was wired to normal closed contacts on the relay then to a sequencer which was used to also energize the electric elements. But G was getting energized on emergency heat and bring on the high speed tap used for AC (normal open contacts) I could not for the life of me figure out why they wired it that way. The only thing I came up with is, I have a Honeywell 8000 stat, and G is energized on a call for emergency heat. I bet the original stat from 30 years ago did not energize G on emergency heat and used the sequencer to bring on the fan.
hurry up and lick the W terminal with both hands on the steel case. 🤣🤣🤣
I almost touched it.
Good job Rick. I would liked to have found out where the 124v was coming from on the W wire. With that fried wire on the contactor, did it somehow get fried inside and pick up 124v from the power leg?
It came from the normal closed contact on the fan relay.
120+VAC doesn’t tingle much past the elbow.
Very true, and only a little further if you're standing in water. However if you're standing on that fiberglass ladder and not touching ground you wouldn't feel a thing.
How in the world did that not fry the xformer?
I think the heat anticipator was the weakest link so it went before the transformer.
Interesting redundant failsafe for the blower
😁👍👍
My cadet electric wall heater was working just fine. All out of the blue it just started blowing cold air. The fan blows. Tested thermostat and works. Kicks in when i set it at warmer temp but just blows cold. I hit reset button, didn’t work, i reset the circuit breaker, no change. Is there a way to fix it or do i have to go buy a new one?
I don’t know your capabilities, so you take all the risks of damage or possible death...
You’ll need an electric meter to check the resistance of the heater element with the power TURNED off and element isolated. then you have to test the thermostat, it should be closed when calling for heat, finally you should check the limit switch and verify its closed. All these things should be checked with the power turned off and verified that its 0 volts AC. each component should be tested by its self with the power off. This is just the basics.
@@HVACRSurvivalthanks so much!!! Truly appreciate it
👍👍👍
I know Jim bob JR
Smart guy.. Nice video
I’m glad you liked the video 👍👍🤜🤛
