Any A/C diagnostic geniuses Out there?
Any Jr. A/C diagnostic sleuths out there?
Here's the problem. Happens intermittently (last time was this morning at 2AM).
A/C stops cooling yet the compressor fan outside continues to run as if all is OK.
Here's what's been done so far:
New Capacitor
New Contactor
New Fan motor
Condensate drain is clear and drain switch tests OK.
Refrigerant is fine
Problem is, every time the repair guy comes out it is working again. It stops cooling usually for a couple hours at random times. Sometimes it can go for 2 weeks without issue then it happens again.
It's an 8+yr old Carrier unit that was part of the original construction (I'm 2nd owner). When it is working it cools perfectly so it isn't a refrigerant issue.
