I admire and respect true professionals who are skilled at what they do and perform their job with at most honesty and integrity. Thank you indeed.
Thank you for the kind words. 🤙
Excellent call on watching the pressures before you left to make sure there wasn’t a high pressure event since you left the switch jumped out. True pro 🤙👍
Thanks man
Thank you for sharing this valuable information is showing as header with the wiring schematic
No problem brother. Thanks for commenting!
Great find man

Thanks
Good video bro 👍
Thanks. Just Subed to your channel. Good stuff from you too!
Dude I really like your videos because of nice approach and explains I just subscribed you. See your next video I am a preventive maintenance technician for residential only. Thanks.
I appreciate that.
That HP switch is very close to compressor discharge port and mounted straight above discharge pipe. It gets continuously cooked at high temp. Usually, they are mounted about twice the distance away from compressor discharge port and branch off to the side to run a bit cooler in temp.
Yea. I hate when they put them that close!
Outstanding job Jeff. Which app were you using for the cap readings?
It's called HVAC School. Available in App Store or Google Play.
I had this done today. I have to leave mine bypass for awhile. Due to the freon thst must be put back in. Mine takes 5lbs. And i have a heat pump.
While mentioning bad HPS I worked for the largest richest newspaper chain no good GANNETT when they were still making record profits years ago. They convinced a commercial refrigeration company to service their numerous roof top units . Rather then pay this company they agreed to place at least two or three nice sized adds in the newspaper. Somebody at the service company wss on the ball and found out that they were not p!acing enough adds then when confronted they would throw add in a Saturday thunder paper of the week that hardly anyone read. So they guy dost opted replacing safety or pressure switches. Would only jump them out. Cost cheap SOB'S $5,000 every time they had to get a over 100' crane to change compressors 40 to 50' from edge if roof.
Was supposed to say two or three adds a month!
That’s one way to get back at someone. Lol.
Give it the old wake-up knock.. never works unfortunately..
I ran across that one time and I fused the run winding on the compressor temporarily so on real high pressures it would blow the fuse instead of damaging the comp...
Great idea.
Can you make more video troubleshooting about Mini split system
🤙
What is that app called you did test capacitor under load ? Thanks
It’s called HVAC School
apps.apple.com/us/app/hvac-school/id1436085954
Is there a link to the follow up installing new switch?
No. Another tech in my company went back to replace.
Why would you cut the wiring, the possibility of a defective plug needs to be established. Just jumping the plug wouldve been easier
Already ruled out the plug before I cut the wiring. Plus I still wanted the LPS to be operational. Jumping the plug would have bypassed both switches.
A LOT of wind noise!
Sorry bout that.
Hmmm.......TRANE XR-17 2-STAGE 4 TON HEAT PUMP UNIT.....GOOD STUFF....surprising the High-Pressure-Cut-Out-Switch failed at only 3.5 - 4 service-life years.....must have been made overseas and "wired-up" in Tyler, Tx. with the main unit.
Yea. I found it strange too. Thanks for watching!
does that pressure switch have a Schrader valve or will you need to recover all the gas to change it?
It’s brazed in. So I’ll have to recover.
Just break it. Lol 😆
The way to fix this without ripping off the customer with all this labor is to just add a tee to the high side schrader valve outside the unit where you'd put you gauge on. Then add your new pressure switch there. Easy and less than 15 minutes worth of effort.
@@billderby1527 Yea, ive done that before. But this unit is under warranty and still has probably 15 years of service left. Rather bring it back as close to factory as possible.
@@billderby1527I would assume you would pull the valve stem core in the original valve before the tee. Right?
