I have a customer who's gas/electric package unit is tripping the breaker. 50 amp 2.5 ton. Wow those units from 25 years ago are energy hogs. No manufacture date to be found, but guess at mid 80's or older. HDP (Carrier)
The caps are good, found one wire that blew off / melted from the contractor. Fix that and it started up making a one heck of a bad noise before blowing the breaker a few seconds later. Intake air filter looked real bad, so suspect the A-coil might look the same. Anyway the customer wants to replace the compressor, vs a new unit with a 10 year warranty.
I suspect its going to be a nightmare going this route. ( repair) Should I recover the r22 and cut open the lines to see if it looks like black sludge or test for acid? I guess at what point do you know when its not repair able. Well I ready should say not worth it.
so far, I'm thinking.
new 40 mfd cap.
