A/C fan quit
I recently bought a 2010 Itasca 24V class C motorhome, which is equipped with a Coleman-Mach roof A/C unit.
I was on park power the other day, had run the A/C in the last half hour but I just had low-fan running at the time. The fan suddenly quit, and would not restart. I don't hear any humming or reaction at all when I move the dial around.
The breaker never tripped, and I've got voltage at the L1 terminal inside the A/C switch panel. However, it's reading lower voltage than my A/C supply.
I'm measuring 97v AC at L1 with everything turned off, and at the same time I'm seeing 125v at the other 110 household jacks in the R/V. I don't know if this is significant or not.
I removed power and did continuity checks on the switch - its doing what the diagram says it should be doing in various fan and cool modes.
I have not found any cut and dried troubleshooting info yet, and I apologize if this question has previously been covered on the board. I did search around before posting, I promise! :)
Ant clues, or things to check next? I tried calling the local shop in my hometown that does A/C, and their phone has been busy nonstop for two days. This is going to have to be DIY repair, I must try at least!
Any help appreciated,
