RV stoves may have issues, and most of the time, they occur when least expected.
Your furnace needs moving components, electronics, gas connections, and sensors in order to start and create warm air, despite the fact that its functioning is very simple.
The furnace is seldom utilized by the great majority of us during the year.
They gather dust and squeak around rough roads the remainder of the year.
In certain situations, during the off-season, they also serve as a haven for rats.
Maintaining and servicing your RV furnace is essential and will significantly lower the likelihood of problems needing repair.
Like everything with moving components, issues will arise eventually.
As we all know, this is particularly true in the world of RVs.
An extensive look into troubleshooting may be found here.
There are several problems that an RV furnace may exhibit.
How Can An RV Furnace Be Repaired?
Let’s concentrate on a chilly air-blowing RV furnace.
The Possible Causes of Your RV Furnace Blowing Cold Air
You must identify the issue before you can resolve it.
As already said, in order to start, function, and generate heat, your RV furnace needs fuel, electronics, and a number of sensors and relays.
The most probable reasons and solutions for an RV heater that is blowing chilly air are listed below.
#1. Boat Switch
RV furnaces often fail to properly ignite, which results in them just blowing chilly air.
The sail switch, a tiny, very sensitive switch, only activates when the furnace fan is running at full speed.
Pet hair, dust, and debris from the RV’s interior, as well as material that has been gathered and blasted about by the fan, might clog this switch.
A fan motor not operating at full speed is a less frequent issue that might pass for a sail switch issue.
As previously stated, the sail switch won’t operate until the fan is running at maximum speed.
Sail switches are a regular issue and, for the most part, a cheap and simple repair, so many RVers choose to have a spare on hand.
#2. Fuel Supply
Let’s start with a statement that ought to be evident.
Have you got gas? The gas valve will not light the furnace if there is no fuel present when it opens.
There will be no flame heating the air; instead, your fan will be blowing chilly or room temperature air.
Verify that you have propane first.
Verify that the tank valve is open in the second step.
Although it may seem apparent, we are all aware of how hurried we might be when putting our site together.
There are many things happening, and occasionally little details are missed.
#3. Gas Shutoff
A gas valve opens when fuel is delivered to the furnace, allowing the gas to be lit and continue to burn.
This cannot occur if the gas valve opens, resulting in a frigid air blowing from an RV furnace.
You can hear the gas valve open when the furnace starts beginning.
When it opens, a clicking sound will be heard.
It’s probably opening if you hear this noise.
A fuel obstruction might be present in a tiny aperture on the gas valve.
It is possible to remove the orifice end and inspect it for debris.
When turning on the furnace, there’s a possibility you’ll hear the click even though the valve is still broken.
If that’s the case, the valve has to be taken out and tested using a 12-volt power supply.
The valve should open when you connect a lead to its two lines, allowing you to blow air through it.
Before removing any gasoline lines, don’t forget to turn off your gas!
Your furnace should produce a quick ticking sound as it attempts to start.
This noise is the combustion chamber’s ignitor’s spark in action.
A spark ignites the gas once it has been supplied to the chamber.
If you don’t hear this rapid ticking, you should look into it further.
When the furnace is attempting to start with the ignitor out of the combustion chamber but still attached (confirm that your gas is turned off), you ought to see a spark leaping between the ignitor tips.
Look for fractures in the ceramic insulation visually.
Verify that the space between the ignitor tips is as the manufacturer intended.
Make sure the gas chamber is in excellent shape and doesn’t have any sizable gaps that might let gas escape before it ignites.
The ignition module on the circuit board is most likely to be the issue if there is no spark or a very weak spark.
The ignition module must be changed as a result.
Testing your furnace before leaving for the weekend is a smart method to identify issues early on, while you still have time to address them and can easily get replacement components.
This winter, avoid being caught with your RV heater spewing frigid air on a chilly night.
