Reasons for RV Water Heater Igniter Not Clicking


Any clicking sound is usually a bad indication. Like if a bomb ticks right in front of you you’ll scream for your life. But when it comes to the water heater igniter the clicking sound indicates that it’s working properly.

In fact, if it’s not clicking that means something went wrong somewhere. And it’s your job to go on a hunt to find the culprit.

Now, the question is what are the reasons behind RV water heater igniter not clicking and how do you solve it?

Don’t worry; we promise we will answer all your queries. That too in full detail. All you have to do is sit back and scroll through our article. So, are you ready? Then let’s start.

RV water heater igniter not clicking: Explanation and Remedy

Well, as promised we will tell you why your igniter is not clicking. But just to warn you there can be several reasons behind this.

So, in order to solve the mystery, we need to tackle the problem one by one. 

Sounds fair? Alright, then let’s begin!

Reason 1: A case of blown-out fuse

In case your water heater igniter is not clicking like usual then the first thing to check is the fuse. You see, if too much electricity flows through the fuse it tends to blow up.

That’s when the entire circuit gets disconnected. As a result, voltage can’t reach the igniter and cannot start up the engine. 

But how can you be sure that it’s the fuse? Well, to eliminate the fuse from a suspect you need to take it out and see if it’s in minted condition or not.

Now, if you find that the fuse is burned then you need to take action to solve it.

Solution: Replace the fuse

Once you identify that the fuse is responsible for the problem you must replace it. You see, a fuse has only one life. Once it bursts you have to get a new one to replace it.

That’s how it’s designed. But on the bright side, once the fuse is replaced your days of worrying for the igniter will be over.

However, if the fuse is safe and secured then there must be another source of the problem. But don’t worry; you’ll find the problem soon. Stay tuned.

Reason 2: No power at the brown wire

The fuse wasn’t the issue? No problem, let’s move on to the next part of the investigation.

For this part, you need to take a look at the brown wire that is right next to the fuse. You see, that’s the earth wire which ensures that all the extra current flows to the ground.

This way you stay safe in case of any short circuit. But this brown wire can also be responsible for the problem with the igniter.

You see if the voltage does not flow through it that means it’s the one causing the problem. So, take out the voltmeter and have a look at it.

If there is voltage running through it then you need to keep on looking. However, if there is no voltage then you need to solve the matter.

Solution: Replace the brown wire

In order to fix this issue all you have to do is replace the brown wire. Once you get that done turn on the igniter.

You see, if the earth wire caused the igniter to stop ticking then this should fix the issue. However, if the problem hasn’t been solved by now then something else must be responsible.

Stick with us to dig deeper into the problem.

Reason 3: Zero power supply at the thermal cutoff

Don’t get disheartened if your igniter hasn’t been repaired yet. Instead, check the thermal cutoff right which is below the brown wire.

Well, to be precise you only have to check if the voltage is running through it. If it is flowing then that’s not the issue. But if it isn’t then you hit the jackpot.

Solution: Replace the thermal cutoff

If you find that power isn’t flowing through the thermal cutoff then you can solve it in two ways. You can remove the thermal cut off and bypass the wires so that it works again.

However, that will not be safe because the thermal cutoff keeps you safe from any kind of fault in the wires. So, for a more permanent solution replace the thermal cutoff altogether.

Reason 4: Dirt at the connectors

One more reason for the igniter, not clicking can be the dirt on the connectors attached to the circuit board. You see, with time dirt and dust starts accumulating between the wires.

That causes the wires to come off. So, the power can’t pass to the control board. If this is the issue then it can be easily solved.

Solution: Clean the connectors

All you have to do is clean the connectors. A few good swipes with a rag will get the job done.

Reason 5: A faulty circuit board

However, if all of the above issues aren’t the ones creating the problem then you need to check the circuit board. There might be some sort of problem there.

Solution: Replace the circuit board

Now, dealing with the circuit board is quite tricky. In fact, only the top tier experts can handle it. So, the only thing to do in this case is to take out the circuit board and take it to the repair shop.

In worst-case scenarios, you might have to replace the entire circuit board.

To wrap up

That’s all reasons behind your RV water heater igniter not clicking. We hope you found the main culprit in your case.

And since you now know the problem you can take action to resolve it. We wish you the best of luck in your attempt to fix the igniter. Stay safe. Adios!
