Why Does My Space Heater Keep Turning Off?

why does my space heater keep turning off

If you’re wondering why my space heater keeps turning off, there are a few things you can check. These include the following: Incompatible voltage or wattage, overheat limit sensor, short-cycling, and damaged electrical cords.

Overheat limit sensor

If you’re a space heater buff, you may have noticed that yours isn’t turning on. The cause is usually a broken high-limit switch. To remedy this tidbit, unscrew the plenum from the heat shield and swap out the wires. In a few minutes, you’ll be back in business.

Luckily, there are a few high-limit switch replacement options on the market. Some heaters have two, while others are equipped with only one. Depending on the model, the replacement is a simple task that should take less than a few minutes.

Before you start rewiring, be sure to check the manual for your model’s manufacturer specifications. This should include the recommended watts or kilowatts. Similarly, if you are in the market for a new model, make sure to ask your sales associate about the appropriate warranty.

Damaged electrical cords

To prevent an electrical fire, you should always check out your space heater’s safety features. This includes its tip-over switch. A good electric heater will shut off automatically when the electricity supply is too low to support the load. If you are unsure, consult a qualified electrician.

Damaged and overloaded electrical cords are common causes of fires. They may even be the culprits behind your home’s latest nightmare. You can reduce your risk of an electrical fire by examining your cords for fraying, cracks, or snags. Similarly, you should avoid squeezing them. Squeezing an electrical cord can cause the insulation to melt, thus leaving your appliance susceptible to an electrical fire.

An electrical space heater’s power outlet is a common culprit. This is because it consumes a lot of electricity. Fortunately, if you are in the market for an electric space heater, you can save a lot of grief by purchasing one that is equipped with a tip-over switch.

Circuit breaker trip

If you have a space heater, you may have experienced a circuit breaker trip. This can be caused by the heater itself, faulty wiring, or other appliances that are in the same circuit as the space heater.

You should have a professional check your space heater. Often, a faulty breaker is a reason for the tripping. In other cases, the electrical cord or heating element of the heater may have to be replaced.

Overloading the circuit can also cause a breaker to trip. When you have a tripped breaker, you should unplug everything from the tripped outlet. Also, make sure the wiring is clean. Exposed wiring can cause short circuits and ground faults.

The easiest way to prevent a tripped breaker is to be careful about the amount of electricity you use. Too much power can be dangerous and can lead to fires. By limiting the amount of power you use, you can extend the life of your devices.

Incompatible voltage/wattage

If you have a space heater, you might have noticed that it keeps turning off and on. This might be due to a faulty air filter, a loose wall outlet contact, or a combination of the two. Fortunately, you can find a solution to this problem.

First, you should check the actual circuit breaker for a fault. In many cases, an electronic short will be the culprit. Second, you should try moving the unit to a different wall outlet. Finally, you should call a professional to investigate the problem. An electrician will be able to perform a thorough analysis of your electric space heater. They can also install a new circuit for you.

When it comes to space heaters, the best way to keep your family warm is to avoid scalding yourself with a flame. The best way to do this is to make sure that you are using the correct settings for the power source. Make sure that you only use a power source that is suitable for a space heater. Otherwise, you might be wasting your money on a unit that doesn’t work.


Short-cycling is a furnace or space heater problem that causes the unit to switch on and off frequently. It can be very uncomfortable, and it can also cause damage to the unit. The constant on-and-off cycles can be expensive, and they can shorten the lifespan of the HVAC system.

Short-cycling problems can be caused by a variety of factors, and it’s best to consult an HVAC technician to determine the exact cause. Once an issue is diagnosed, the technician can perform a repair.

Most modern furnaces come with a built-in safety device to prevent short cycling. However, there are other causes of short cycling, and a faulty temperature-monitoring component can contribute to the problem.

A dirty flame sensor can also cause the unit to shut off. This is because the sensor can’t gauge the gas flow to the burner.
