AC / Heat not working

[Ulspeed]

Any ideas why my AC & Furnace won’t come on? All batteries are charged, all fuses and breakers are in working order. We have 2 AC’s on 50 Amp and neither are working so it’s not just something with one unit. It’s a 2016 Coachmen Pursuit 27KB. Any help would be appreciated!

A problem with the thermostat itself would affect all of those units together. Does the thermostat seem to appear and to be acting normal?

Hello and sorry for your issues. As another poster said does your thermostat appear to be working> try turning the fan on only from the thermostat and see if the fan comes on. If it does not the thermostat is probably not getting power and If I recall that is powered by 12 volts not 120 like your a/c. Now the bigger question is where does the thermostat receive it's 12 volts from, and the answer to that unfortunately will have to come from another member as I am unfamiliar with your coach. The only thing I can offer is to make sure your salesman switch is on which is what supplies 12 volt power to the coach via the house batteries. Hope this helped some, good luck

Have you recently done any work on your roof AC units?

If so check the dip switch settings on the units. You might have accidentally

changed them.

There are master reset for most electronic thermostats. Usually a zone programming issue comes up as reason. Has these ever worked for you.? An issue come up from time to time a random 120v breaker being off tied to the energy management system keeping an AC off but not the ACs breaker.

Funny story friends where camping in the same campground I was and their AC wasn’t working. Their power cord got pulled out and they where running off of batteries and didn’t know it.
