Why Does My Electric Heater Keep Turning Off?
It can be very frustrating when your electric heater keeps turning off on you. There are a few things that you can check and fix to make sure that your heater doesn’t keep turning off. These include the power source, the thermostat, and the overheat limit sensor.
Check the power source
If you have an electric heater that keeps turning off, the first thing you should do is check the power source. You can do this by plugging the device into a different outlet. Alternatively, you can test the device at a friend’s house.
In some cases, the best option is to have a professional check the circuitry in your home. An electrician can look at the circuitry of your heater and make the appropriate modifications. He can also determine how much power you have available at the wall outlet.
Another test that will help you decide whether or not to have your heater serviced is to plug it into a friend’s home. They may be able to tell you if your unit is defective and can recommend the next steps.
A space heater that shuts off is usually caused by a malfunction in the circuitry. This could be a malfunction in the thermostat or the wiring of the heater.
Check the air filter
If your electric heater keeps turning off, you may have a clogged air filter. In this case, you need to get your filter replaced as soon as possible. Not only will a clogged filter cause your furnace to shut off, but it could also prevent your heating system from blowing warm air into your home.
Air filters should be cleaned or changed at least once every three months. They are designed to screen dust particles and allergens out of the air. When the filter becomes dirty or clogged, it blocks air from passing through the ducts. This can cause your furnace to shut off and cause your electric bill to go up.
A dirty air filter can also lead to an overheated furnace. An overheated furnace will not work well and could result in an electrical fire.
The Environmental Protection Agency (EPA) recommends checking the air filter of your furnace at least once a month. If you have pets or dusty conditions, it may be more often.
Check the overheat limit sensor
If you are having problems with your electric space heater, it’s probably because of a faulty sensor. There are several things you can do to test for this. However, it’s best to contact an electrician if your home power supply has failed. Depending on your specific model, the best way to check for this would be to unplug large energy users from the wall.
The primary limit switch is a good place to start. This is the device that triggers your blower motor when the heat exchanger reaches a certain temperature. For this particular device, the temperature is measured by a capillary tube connected to a bulb.
A tip-over protection button is also a good place to check. Generally, this is a simple button found at the base of the unit. To press this, you need to touch it on a smooth surface. When it’s pressed, the button assumes the heater is upright.
The overheat limit sign is the least obvious, but it is a good place to look. Typical limit signs are located in the furnace cover panel, outside the hot air supply plenum, and outside the gas valve.
Check the thermostat
When an electric heater keeps turning off, it may be an indication of a problem with the thermostat or another component. However, the most common problems are with air filters. If the heater needs repair, a qualified technician can diagnose the issue.
First, check the wiring. There may be loose wires that cause the thermostat to shut down. You can tighten loose wires with a flathead screwdriver.
Secondly, check the circuit breaker. If the circuit breaker trips, this means that the electrical system is overloaded. In this case, you should switch the breaker back to the on position.
Thirdly, check the temperature of the heating elements. A faulty heating element will have a bright orange glow. Also, check for a burning wire terminal. This is an indication that the thermal fuse has been blown. The thermal fuse is hidden in a part of the heater, usually behind the insulation.
If the heat elements or voltage detector are working properly, you’ll find that the heater is operating at the correct temperature. If not, you may have a faulty power supply.
