Why Does My Propane Heater Keep Shutting Off?

why does my propane heater keep shutting off

If your propane heater is suddenly shutting off, there are a few things you can check. First, you’ll want to clean out the pilot tube and thermocouple to ensure they’re clear of any debris. You can also look for a faulty electrical connection or a dirty thermostat.

Cleaning the pilot tube

If you have a propane heater that keeps shutting off, it may be time to start cleaning the pilot tube. Keeping the pilot tube clean can help keep the burners working properly, but it will also keep your propane heater from becoming a hazard.

Cleaning the pilot is not difficult and can be done quickly. A simple brush or cloth can be used to remove dirt and debris. Keep in mind to use flame-resistant gloves. It is also important to make sure the gas line is not moved while heating.

You can blow air through the pilot tube to clear out any buildup. This will also drive out soot from the pilot light. When you are finished, you can relight the pilot.

The pilot feed tube is attached to a small brass fitting. This hose should be cleaned regularly to ensure a smooth flow of gas to the pilot.

Dirty thermocouple

If your propane heater shuts off, it may be due to a dirty thermocouple. This is a simple electrical device that measures the temperature of your gas flame. It is used as a safety device to prevent gas leaks.

Whenever you light the pilot, an electric current is sent through the thermocouple. If it is not receiving heat, it will cut off the gas supply.

Dirty thermocouples can be caused by many different things. It is best to remove the thermocouple from the pilot assembly and clean it. There are several ways to clean the thermocouple.

You can use a lint-free cloth or sandpaper. Sandpaper can help get rid of dirt and debris. Rust can also be removed with sandpaper.

You can replace the thermocouple on your own or you can hire a professional. In either case, you will want to follow the instructions provided by the manufacturer.

Faulty electrical connection to the igniter

A faulty electrical connection to the igniter may cause your propane heater to shut off. This is a common problem, and there are several reasons why this happens. If you notice your propane heater shutting off, it’s time to investigate.

The first thing you should do is test the ignitor. A faulty ignitor may make your furnace malfunction or even cause a fire. For example, a broken ignitor may create an unsteady flow of warm air.

You may be able to solve this problem by removing the pilot tube and inspecting the area. Usually, the pilot tube is connected to the gas valve. Make sure that the sleeving is clean and the connections are tight.

Another problem that may be causing your propane heater to shut off is a clogged or dirty air filter. Clean the air filter regularly.


Aside from keeping your gas tank at a reasonable temperature, propane heaters also have a fair amount of safety features to keep you and your family safe. It’s easy to see why a spooky gas hose or a spiky pilot tube could put your home on the fritz. But how do you fix the problem? The good news is that there are a few steps you can take to get the job done right. For starters, check your gas hose for leaks. If that doesn’t do the trick, you might consider a trip to the hardware store for a new hose or a new pilot tube.

While you’re at it, you might as well check your aforementioned air intake for debris and obstructions. And if your air filter is a little plugged up, you’re in luck.

Low gas pressure

If you have a propane heater that keeps shutting off, there is a good chance that you have a gas pressure issue. This problem can be fixed with a few simple steps. But before you start, make sure you have the right information.

The first thing to check is the pilot light. A pilot light is a small flame that helps to prevent gas leaks. When the heater does not receive enough gas, the pilot flame will shrink.

Another cause of the problem is the main gas line. This line should be clean and free of kinks and loose connections. If you can’t find a kink in the line, your propane heater may need to be repaired.

Another common reason for a propane heater, not lighting is a dirty or clogged pilot tube. This can be caused by dirt, soot, or debris on the hose. Using a cloth to remove the debris will help to keep your heater running properly.
