That’s a good catch a lot of techs don’t even know the symptoms of an over feeding meter device and will not acknowledge it and blame the compressor when it fails
Thanks! Great question high subcooling is usually a result of liquid backing up in the condenser but when the metering device is overfeeding there's no back pressure being created in order to cause refrigerant to backup in the condenser... also the customer never even noticed this is just something I found on a routine maintenance.
Two reasons to have the thermistors well wrapped with thermal tape with tie wraps on ends of wrap. Air flow across sensor will raise the temp reading a bit and condensation on sensor will eventually intrude into epoxy wire end seal of sensor damaging sensor. Looks like you are showing a third reason of growing dissimilar metal corrosion. If someone had salty fingers on copper pipe before placing sensor clip on it that could create possible corrosion with moisture.
Awesome trouble shooting video for this unit, thank you!!

Thanks for the feedback!
Nice diagnosis!
Thanks!
Nice work
Thanks!👍
Nice troubleshooting skills
Great informational video. May I ask what the symptoms were, please? Thanks.
Thanks! low super heat High suction saturation temperature low liquid saturation temperature and low sub cooling temperature split was okay
Hey man, I wish you could work on my system! Do you have that link you mentioned around 5:55?
You should have the Service Manual that comes with it, if not just google it. You can pull any page up
Fam whats the name of your company and what state do you all work out of
Quick question, so if the eev was over feeding, how come the sub cooling was low instead of high? Great video btw

Also what was the customer complaint?
Nice man good job 👍

Great points! I didn't even consider the condensing and causing moisture to get into the wiring. Appreciate the feedback and thanks for watching!
What app r u using to read ur temps?
Measure quick
Very Nice 😎👍😎👍😎👍
Thanks man! How's life in treating you?
