But before that, you must understand the issues that cause this crisis.

So, why your Atwood RV furnace won’t ignite and how do you solve it before you freeze to death?

Honestly, there can be a number of reasons behind this problem. And each problem needs a special solution.

So, why don’t we take a look at each of these problems and solutions using a close eye?

The explanation for why the Atwood furnace won’t ignite

It’s time to take a look at the main problem. Then take the proper steps to solve the issue.

Now, before we start, we have to warn you that there are many reasons that can be responsible for the problem. So, you need to have some patience to go through all the reasoning.

After that, you will be able to pinpoint the problem and take action accordingly. Do you think you’re up for the challenge?

Yes? Great! Let’s get things started then.

Reason 1: An uncharged battery

One of the primary reasons for not able to ignite your furnace is an uncharged battery. It’s quite easy to forget to charge up the battery.

In fact, most people forget to charge it. That’s probably because it’s not as fascinating as a phone. And if this is the case there is no need to worry.

That’s because solving this is a piece of cake.

Solution: Charge up the battery

You might already know how to solve this issue but let us state the obvious here. All you have to do is charge the battery and your Atwood RV furnace will ignite again.

Yep, it’s that easy. However, if your problem hasn’t resolved yet then stick with us to find out the real problem.


Reason 2: Not enough gas in your tank

Another reason for having an ignition problem is not having enough gas in the tank. You see, the furnace runs on propane gas. So, once it runs out you won’t be able to get it to start again.

At the same time make sure you actually turn on the propane gas. So, that gas can flow to the tank. Otherwise, your tank won’t startup.

Solution: Refill the tank

Well, this problem can also be solved quite easily. All you have to do is refill the tank with gas and you’re all set.

Your furnace will run smoothly and keep you warm when the sun is down. But if you have a full tank then your problem might lie somewhere else.

Don’t lose hope. Keep on reading to figure out the right reason.

Reason 3: A faulty igniter

You might be aware of this but in case you don’t know the igniter is the main element of the furnace. If something happens to it then your furnace won’t ignite at all.

So, check to see if the furnace is the one causing the problem or not. If it is the main culprit then you need to resolve the matter.

Solution: Replace the igniter

The first solution while dealing with a faulty igniter is to find a way to fix it. Maybe it’s covered in dust so a good wipe can solve the problem.

However, if the igniter is beyond repair you have to replace it. After that, your furnace will work like before.


Reason 4: Corroded contacts at the thermostat

The corrosion from the batteries can stop the thermostat from working. This happens because the alkaline batteries melt over time and begin to corrode.

 And if the thermostat is down your furnace will not be able to generate heat. So, you need to take measures to fix this problem at once.

Solution: Clean the contacts

The first thing you have to do in order to resolve this matter you have to throw away the batteries. Then you need to run and get a paper towel. With that, you have to clean the loose corrosion.

Then take some cotton and dip it in white vinegar. Then use the dampened cotton to clean the contacts. Once you get it cleaned run the thermostat to see if it works.


Reason 5: Sticking gas valves

One more probable reason for failure to ignite a furnace is because the gas valves keep sticking out. You see if the valves don’t stay in their position the gas won’t be able to reach its destination.

And so you will be left behind to feel cold as ice. You certainly don’t want to shiver all night, do you? So, you have to take action to solve the matter.

Solution: Cover the valve and tap on it

So, to get the gas values in their place all you have to do is hammer the valves. Now, for this, you can either use a hammer or the hard part of a screwdriver.

However, before you do that you must cover the valve. Otherwise, you might end up damaging the valve permanently. And that will lead to another disaster, one that you certainly want to avoid at all costs. 

To wrap up

That sums up all the main issues that can explain why your Atwood RV furnace won’t ignite. We certainly hope you found out your problem.
