Furnace and A/C down

[Ruediger]

The day i bought my rv, all applicances worked properly. After shipping the vehicle to europe, i still have in my mind, that the coleman thermostat clicked, while adjusting the temp. But not sure. I did a lot of tlc in the meantime. Here my question: furnace and ac dead. Fuse checked. I have one in the back, combined with the waterheater. That one working properly. I started then gen, testing the ac. Nothing. Are there possibly any other fuses? The thermostat with 6 cables. The basic one from coleman without display. Could it be the reason? The furnace itself with 12v as far as can see. Any option to bridge the thermostat and start the furnace 'manually'? Same with the ac? Im stuck how to start and isolate the problem. Any recom appreciated.

May be helpful to know what RV you are working on. Next we need to know how you verified power to RV. The more details you can provide on steps completed the better we can help diagnose.

Troy, the rv spec in my profile. Chevy P32 chassis from 2021. All testing based on my house batteries. All other appliances working. I follow the vid from the the first post. And will look also for breakers.

You first comment the path for success. I didn´t know that the breaker is a breaker also for the thermostat panel. Always helpful advice right here. Thanks. Problem solved.
