A/C Thhermostat??

[sullivd]

I have a 2007 Fleetwood South Wind 32V. When I turn the thermostat on A/C I get nothing. Even when I toggle between A/C 1 and A/C 2. Can't change any settings. Heat setting and heater works fine. Question is the problem with the thermostat or with the A/C units?

Any suggestions appreciated.

Somewhere I found a more intense rest. Could not find it right off.
Not only it had pulling fuse but disconnecting a connector that many times is stuffed into the wall behind the thermostat. Pulling the fuse didn't work on some as it did not disconnect all power to it.
There was a longer wait period for it to reboot. Memory serves me it was like 20 minutes.
OP: It would be good to know which thermostat you have.

Brand/model of Thermostat? Would help trouble shoot. They are not all thje same.

Depends on the thermostat.
Some sends a signal at a difference pulse or what ever to operate individual devices. The signal in some cases can be disturbed by flourescent ballasts that are starting to fail and puts out a signal similar to the thermostat.
What is make and model of the thermostat?

Might be the board in one of the AC units. My thermostat is connected to one of those boards which controls everything.

Remove cover, then remove fuse, wait 15-20 seconfds then reinstall fuse. let system reboot.
If you have any flourescent lights, turn them off.

would be extremely hard to believe both AC units quit working at the same time
