When the furnace does not work, it is important to know why. The furnace has a safety switch that will turn off the furnace if there is a malfunction in the system. If this switch is not working properly, the unit will not turn on.
The most common reason for an issue with the furnace is a dirty filter. The filter blocks air from entering and exiting through the unit, which causes it to overheat or under-heat. This can cause damage to internal parts of the system and can even create a fire hazard.
How do you reset the furnace in an RV?
The lockout condition can be reset by turning the thermostat off and reducing the temperature to a value which would not cause the furnace to turn on. Wait approximately 30 seconds and then turn the thermostat back on and increase the temperature to the desired level.
Why won’t my furnace in my RV turn on?
Check to see if your battery is putting out 12V at the furnace. If there’s not enough voltage coming from the battery, the fan won’t run. The heat runs on 12V, not 110. Otherwise, it could be a tripped circuit breaker or a blown fuse.
Why Is My RV furnace running but no heat?
It’s not uncommon for an RV furnace fan to run but produce no heat due to an issue with the sail switch. Among the possible problems is low battery voltage. So, check your RV’s house batteries to make sure they’re not weak.
Why Is My RV furnace blower not working?
Most furnace blowers on RVs need about 12.3 volts to fire properly, so if you’re not getting that much juice, the battery is probably the issue. What is this? You can charge the battery for a few hours and then test it again. If the issue hasn’t improved, you might have a damaged battery.

Is there a fuse for RV furnace?
RV furnaces have fuses to keep the circuits inside from overloading. Many technical issues with an RV’s furnace can be attributed to a blown fuse, which is usually the result of damaged wiring or a short circuit. If this is the case, changing the fuse won’t fix the furnace.
Can Hear Your RV furnace click on but it does not fire up?
Most likely, your furnace is making a clicking noise and not providing heat because your furnace’s spark igniter is trying to ignite your pilot light or burners but is failing to do so. In other words, there’s an ignition system malfunction that needs to be fixed. Otherwise, your furnace won’t start.
How do you reset an RV furnace after running out of propane?
An Alternative Way For Restarting The Furnace Turn off the gas valves of the furnace to prevent the flow of propane. Turn on the burner now. Let the burner burn for a couple of minutes to let the residual gas from the valves and airflow out. Now open the gas valves of the furnace slowly and restart the furnace again.
How do you test an RV furnace ignitor?
Test The Ignitor With A Multimeter Set a multimeter to the lowest possible resistance test and place the probes onto tips of the plug for the ignitor. If the multimeter shows infinity or stays at zero, the ignitor no longer works and must be replaced.
Why Is My RV blowing cold air?
An RV furnace blowing cold air is a telltale sign of an issue with the furnace’s sail switch. Whether it’s low power voltage or something clogging the switch, an issue with the sail switch can stop the furnace from igniting without stopping airflow, resulting in a gust of cold air.
Where is the flame sensor on my RV furnace?
A furnace flame sensor is a very basic part of your furnace. It’s located on the burner assembly and is just a thin metallic rod. It’s usually bent, and it sits just in front of the pilot flame inside the furnace.
How long does it take an RV furnace to heat up?
2. Know about furnace cycling. Your RV propane furnace will take 15-30 seconds to come on after you turn on your thermostat, and then run for another 15-30 seconds before you start feeling the heat.
