A/C help needed. Coleman mach 8 .. Quartzsite
I was away and got a text that the a/c was no longer working.
I came home to the RV about an hour or more later. The two interior fan speeds work. When i switched to a/c, I think I heard the compressor come on.
So I climbed up, and pulled the wires off the capacitor. Discharged it. Measured like 5-6 Mohms... and climbing i think i remember.
Then I measured the compressor...
C-S 5.5 ohms
C-R 1.3 ohms
S-R 6.2 ohms
But now I remember, the black wire from the compressor was still connected to the board. Was the black the common? Maybe it made no difference if it was just grounded?
So I put it back together, and it seemed to run for a few hours, but It wasn’t making cold really well. So I was thinking, maybe it needs coolant. It has a port installed and was charged at the beginning of the summer.
Then, a little while ago, it kind of cycled off, but in a weird way that drew my attention. Maybe it made a different sound than normal. Nothing dramatic as far as a sound that I can report here.
But i turned thermostat knob to very warm to just let fan run for awhile.
Then after about 10 min, turned it cooler and cooler, but nothing happened. I didn’t hear any attempt at compressor turn on.
Then I left thermostat at very cold setting and went to fan only for awhile. Came back to a/c .. nothing.
What should I do now?
