The RV furnace is an important part of the setup and needs to be working properly.
If your RV furnace is starting to give issues, this is a sign there’s something wrong and it likely has to be addressed before the furnace gives out completely.
In general, you should be looking at potential noises the RV furnace is making that might stand out to you. This can include an RV furnace that’s clicking but not lighting.
If the RV furnace is clicking but not lighting, it’s best to start by inspecting the air filter for clogging. Next, check to see if the thermostat is damaged and the propane is coming through as required to light the furnace. If this is fine, check to make sure the safety switch didn’t trip.
The clicking noise tends to come when the RV furnace is attempting to start up. This likely means it has enough power to do this but is not going all the way through to the part where it does get lit.
This is why you need to focus on the main steps for fixing an RV furnace that’s clicking but not lighting.
Steps On RV Furnace Clicking But Not Lighting
1. Check The Air Filter For Clogging
If the RV furnace is clicking but not lighting, it’s recommended to check the air filter first.
The air filter is going to let you know when there is something wrong with the part that has to be addressed.
It’s common for the air filter to get to the point where it has to be swapped out. If you don’t take the time to change the air filter in the RV, this is going to take away from how it ends up doing over time. You need to stay on top of this as an RV owner.
This is not only going to impact the RV furnace but the rest of the vehicle too.
Clogging is not good and that is the first thing you are going to want to look into when you are hoping to address what the underlying issue is. If you are not checking the air filter, you are not going to feel secure with what you are getting.
2. Look For A Damaged Thermostat
Look at the thermostat.
When the thermostat is not running properly, this is not going to start up the RV furnace. It is not going to ignite and that is a real concern.
The thermostat has to be running correctly for there to be enough for the RV furnace to run. Otherwise, you are going to continually hear the clicking noise.
The best thing you can do is try to reset the thermostat or replace it if the part is damaged. This will depend on what is going on with the thermostat and what needs to be done to stabilize it.
3. Ensure The Propane Is Full
You will want to take the time to make sure the propane is in good shape too.
A lot of people don’t take the time to think about how the propane is doing. This creates a situation where the propane is not getting through to the RV furnace and that is the real concern.
You have to make sure the propane is going through to the RV furnace and it is delivering the type of fuel that is required to get the part to run.
4. Check The Safety Switch
The last thing you will want to address is the safety switch.
There are situations where the safety switch will act up and that is going to create a situation where the RV furnace is not going to run until the switch is turned off.
Look for this switch and make sure it is off.
You might have to go through the owner’s manual to know where the safety switch is set up. This will vary depending on the make and model of the furnace.
Work your way through this detail to make sure things are as safe as they need to be. Otherwise, you are not going to be happy with how the RV furnace is running over the long haul.
Final Thoughts
It’s essential to look into this when it comes to an RV furnace clicking but not lighting.
If the RV furnace is clicking but not lighting, the most common reasons include not enough propane going to the furnace, a bad thermostat, a clogged air filter, or a safety switch that has turned on. To fix the issue, address these parts and make sure the safety switch is off.
As long as you do this, the RV furnace is going to start up as soon as you need it to.
Issues with the RV furnace do pop up from time to time but you can figure things out as long as you are paying attention to what is causing the noise to come.
