Troubleshooting Guide: Space Heater Keeps Turning Off, Won’t Turn On – Repair, Cleaning Tips & Replacement Parts Near You

Why Does My Space Heater Keep Turning Off?

Space heaters are a popular choice for many households, providing a convenient and efficient way to heat specific areas. However, it can be frustrating when your space heater keeps turning off unexpectedly. In this article, we will explore the common reasons behind this issue and provide troubleshooting examples and solution suggestions to help you resolve the problem.

1. Overheating Protection

One of the most common reasons why a space heater may turn off is due to its built-in overheating protection feature. This safety mechanism is designed to prevent the heater from becoming too hot and causing a fire hazard. When the internal temperature of the heater exceeds a certain threshold, it automatically shuts off to cool down.

To troubleshoot this issue, ensure that your space heater is not placed near any flammable materials or obstructed by furniture. Make sure there is proper airflow around the heater to prevent overheating. Additionally, check if the heater’s air intake and outlet vents are clean and free from dust or debris, as this can also cause overheating.

2. Tip-Over Protection

Another common safety feature found in many space heaters is tip-over protection. This feature automatically shuts off the heater if it is accidentally knocked over or tilted beyond a certain angle. It is designed to prevent accidents and reduce the risk of fire.

If your space heater keeps turning off, check if it is placed on a stable and level surface. Ensure that there are no objects or obstacles that could cause it to tip over. If the heater is equipped with a tip-over switch, make sure it is functioning properly and not stuck in the off position.

3. Power Supply Issues

In some cases, the problem may not lie with the space heater itself, but rather with the power supply. If your space heater is not receiving enough power, it may turn off intermittently. This can happen if the electrical circuit is overloaded or if there are issues with the outlet or power cord.

To troubleshoot this issue, try plugging the space heater into a different outlet or using a different power cord. If the problem persists, consider checking the electrical circuit to ensure it is not overloaded. If you are unsure about electrical work, it is always best to consult a professional electrician.

4. Faulty Thermostat

A faulty thermostat can also cause a space heater to turn off unexpectedly. The thermostat is responsible for regulating the temperature and turning the heater on or off accordingly. If it is not functioning properly, it may incorrectly detect the room temperature and shut off the heater prematurely.

To troubleshoot this issue, try adjusting the thermostat settings or replacing the batteries if applicable. If the problem persists, it may be necessary to replace the thermostat altogether. Contact the manufacturer or a professional technician for assistance with this repair.

5. Replacement Parts for Space Heaters

If you have tried troubleshooting the common issues mentioned above and your space heater still keeps turning off, it may be time to consider replacing certain parts. Some common replacement parts for space heaters include:

  • Heating Element: The heating element is responsible for generating heat in the space heater. Over time, it may wear out or become damaged, leading to issues with the heater’s performance. Replacing the heating element can often resolve the problem.
  • Thermostat: As mentioned earlier, a faulty thermostat can cause the space heater to turn off unexpectedly. Replacing the thermostat with a new one can help restore proper functionality.
  • Power Cord: If the power cord is damaged or frayed, it can cause intermittent power supply issues, leading to the heater turning off. Replacing the power cord with a new one can solve this problem.

When it comes to purchasing replacement parts for your space heater, it is recommended to contact the manufacturer or an authorized service center. They can provide you with the correct parts that are compatible with your specific model. Additionally, they can offer guidance on how to properly install the replacement parts to ensure safety and optimal performance.


In conclusion, there are several reasons why your space heater may keep turning off. It could be due to overheating protection, tip-over protection, power supply issues, or a faulty thermostat. By following the troubleshooting examples and solution suggestions provided in this article, you can identify and resolve the problem. If all else fails, consider contacting the manufacturer or an authorized service center for further assistance. Remember, it is important to prioritize safety and consult professionals when dealing with electrical appliances.
