Why Does My Space Heater Keep Turning Off?

why does my space heater keep turning off

There are several reasons why a space heater may turn off. This includes overheating, a faulty power socket, or an overheating limit sensor. If you’re having one of these problems, it’s important to understand the causes so you can fix them.

Overheat limit sensor

If your space heater keeps turning off, it might be a good time to have it checked out. You don’t have to buy a new one, you can simply perform the right kind of maintenance to keep it running efficiently. This will also help to avoid any potentially hazardous fires in your home.

First, you should check your power supply. Sometimes the home circuit just doesn’t provide enough electricity to your heater. If this is the case, your unit should be checked out by an electrician.

Second, you should check out the flame sensor. These devices monitor the temperature of the flame and register it on a rod that extends out from the plenum. Performing this maintenance task will allow you to see when your heater has overheated. While you are at it, you might also want to clean the rod with some sandpaper.

Insufficient power source

The most effective way to power a space heater is to choose a circuit that is dedicated to the task. However, if this is not possible, a plug-in device that is compatible with your current setup can get the job done. You should be cautious though, as space heaters can consume quite a bit of electricity and can be a hazard if not properly insulated.

While you’re at it, be sure to use a GFI circuit breaker to keep your home free from electric gremlins. A good electrician can help with this task as well. It’s worth noting that a large heater powered by insufficient amperage can overload your system. Also, ensure that you don’t overheat the components by letting them cool naturally. This is especially true if the space heater is located in an area with low humidity.

Damaged electrical cords

A damaged electrical cord can increase the risk of a fire. This is especially true when the wiring is exposed. If you see a frayed cord or a kinked wire, it is recommended that you replace it.

You should never use extension cords for anything other than temporary purposes. They can be overloaded and cause a fire. To prevent this from happening, try using wall outlets. Or you can have an electrician check your circuitry. He can also measure the power available in your wall outlets.

The first step to preventing this from happening is to make sure your home has working smoke alarms on every level of your house. Also, you should plug appliances into a wall outlet rather than an extension cord.

Another problem you should look out for is loose outlets. Loose outlets can cause a heater to work intermittently. These problems can be fixed by tightening the wire nut connections in the box behind the outlet.

Faulty power socket

If your space heater is constantly shutting off then it’s time to find the cause of the problem. Many times the problem lies in a faulty power socket. While it may seem silly to think that a broken power socket will cause your space heater to keep turning off, it’s quite common.

In addition to being a safety hazard, a faulty socket will also burn up your electrical wires. If you don’t have a handyman in the family, then you’re likely to need a qualified electrician to replace your faulty wiring.

The most important thing to remember when it comes to replacing an outlet is to order the right one. A lot of outlets come in different styles with different types of plug prongs. You’ll want to choose the one that has the best quality and looks the best in your room.


If you have a space heater that keeps shutting off, it’s important to check the internal components before assuming it’s an issue with your product. Occasionally, you may have faulty wiring or an overheating problem. It’s best to have a service technician diagnose your problems.

The first thing to check is your power supply. A tripped circuit breaker is a warning sign. Try plugging your space heater into a different wall outlet to determine whether or not it’s a power supply issue.

Other causes for a heater to keep turning off include overheating and a faulty air filter. If you have a heater with a faulty air filter, you’ll notice that the fan begins to slow down or stop working. This can be caused by a clogged air filter that’s obstructing airflow.
