A/C Not Working

Can you turn that A/C Unit FAN manually ON?

Is that A/C Unit t-stat wall mounted OR part of A/C Unit?

Have you checked DC Fuses for a bad fuse.......not just looked at them but checked that none are blown?

A load shed should shed more than just a single AC unit but of course, we're talking about the RV manufacturing industry where they need to unzip their pants to count past ten.

First order like j-d suggests is to determine if this is a forced disconnect, or if a forced disconnect is possible (equipment there or not installed) then find out what ELSE is connected to the load shed. Usually load shed should be auto recycle meaning it should reset itself automatically. Start hunting and see if anything else may not be working including receptacles (wall sockets).

Have there been any changes in how the coach is connected to shore power? Does this coach have any kind of load manager/shedder? Or 12VDC issues that would cut the power off to the thermostat?
Winnebago has lots of wiring diagrams on their website. Good place to start.

The ONLY reset is the 120 breaker. I would be much richer if every time a customer has called and I ask about the breaker and they state they "checked" it, and they then come in and I walk out and find the breaker tripped. Some breakers "look" fine but you MUST turn it OFF and then on and you realize that it was tripped, it was just not sticking down like you thought it was. Doublecheck all the breakers. turn all off and then on again. Doug

Could be bad run cap or PTCR. If your not comfortable around electricity you should call a mobile tech. There are Youtube videos.
