1) I need someone to confirm the specifications for a dual capacitor that should be installed in the outdoor condenser unit of a Amana Prestige RCE60C2A . I want you to check the literature. I'll explain in a bit.
2) I need to figure out why the outdoor fan on the condensor unit stops running after a few minutes of operation, and won't restart with the "pencil/stick" trick. I've already examined a variety of things.
Two months ago HVAC tech replaced my first capacitor in my Amana Prestige RCE60C2A with a 80+5 MFD capacitor. A week ago my AC stopped working: the compressor would not start. I checked the capacitance of the installed capacitor and determined it had failed. I was advised on JustAnswer to replace this capacitor with a 40 + 7.5 MFD capacitor.
I installed the 40+7.5 MFD capacitor today. The compressor started up and the house started to cool. The issue now is that after a few minutes of operation the outdoor fan stops running, eventually the compressor sounds labored, and it shuts off, probably to protect itself. As a test I attempted to restart the fan while the unit was still on by prodding the fan blades with a stick. The fan blades run smoothly but the fan will not start.
The HVAC tech's capacitor was 80 +5 MFD. The new capacitor is 40+7.5. I am wondering if it is possible the fan capacitor is supplying too much power, overheating the fan and causing the fan's thermal protection to kick in. This is why I want an authoritative answer for what the correct capacitor rating is for my unit.
If the capacitor isn't the issue, I would like to figure out what is wrong. The fan seems to run correctly while it is running.
I went into the attic and very carefully cleaned the fins around the evaporator coils on the indoor unit. They were not particularly dirty and I don't think this was the problem.
Filters have been replaced and are clean. The system is about 6 years old.
