This is a common problem that can be fixed in a few simple steps. Here’s how to fix it:
Fixing the Problem
- Make sure that the furnace is plugged in and operating properly by checking for power with an electrical tester.
- If your vehicle has a thermostat, make sure it’s set to the appropriate temperature for your climate.
- If you have a digital thermometer on the furnace itself, use it to make sure that the temperature at which you want your RV furnace to operate is correct (this should be set at around 120 degrees Fahrenheit).
The Heater Or Air Conditioner Won’t Turn On
If your heater or air conditioner won’t turn on, it could be for a multitude of reasons. The most common problem is that the circuit breaker has tripped.
Fixing this Problem
To fix this problem:
- To do this, you just need to remove the panel that covers your circuit breaker and then flip the switch back on. This will allow you to see if there is a problem with the breakers or fuses.
- Make sure all of the connections are secure. To do this, use a screwdriver to tighten any loose screws or bolts. If any wiring is not connected properly, it can cause short circuits that could cause your AC or heater to stop working altogether.

Fixing this Problem
- First, check the unit power cord. Make sure it’s plugged in correctly and that the outlet is functioning properly.

RV Comfort ZC Thermostat Not Responding
If you have a Comfort ZC Thermostat unit, you may have a problem with it not responding. We’ve put together a few common issues that may cause this problem, and how to fix them.
1. Check Settings
- First, check your settings on the thermostat itself. This can be done by going into the menu and selecting “Settings” from the top menu bar.

- Try turning these off completely if you get an error code so that they don’t accidentally affect responses from your RV ZC Thermostat
2. Check Vents

The vents on your RV could be clogged with debris or not properly installed. Check all vents in the RV, both the ones on the wall and those on the roof.
