2018 Seneca 37TS-the bedroom AC/Heat works. The front coach AC, Heat, or Fan will not turn on by the hall thermostat. Heat works on propane. Everything worked 3 wks ago. Seems it should be a simple answer. Cannot find that any circuit breaker or fuse is out.
Is there a fuse located in the Tstat? And, put your multi-meter on the Tstat wires. Make sure you have 12-24 Volts DC there. Could be the control voltage right there. And, pull the mini fuse in the breaker area and check for continuity between the fuse legs to make sure it is good. After that, it's checking for 120 VAC to the AC unit at the AC unit itself...
