Today's Coleman Mach 15 Incident
We're right on a beach in FL, temp in the upper 90's with high humidity, bright sun and no shade. Our A/C had been keeping the coach on the warm end of the comfortable range, around 80. Till this afternoon. It'd run 10 minutes, compressor shut down, need 20 minutes to recover on High Fan Only, then run another 10 minutes. I went to the roof to do two thingd:
1. Verify that the Evaporator and Condenser Coils I'd recently cleaned, were still clean.
2. Test and possibly Replace the Compressor RUN Capacitor. This is a 40 uF capacitor, and I had a new spare. Old (from 2002) capacitor read 36 uF on my Fluke 12. New read 40. I don't think 10% off spec is too much, but I installed the new one and buttoned the unit up.
It has run since, blows colder, and sounds better. I can only figure the capacitor has gotten "tired" without total failure. It isn't swollen or leaking.
VERY glad I had a spare!
