Pelonis Heater Keeps Turning Off [Quick Ways to Fix]

Pelonis space heaters are great for keeping your household warm in winter, especially when temperatures drop to sub-zero levels. But these appliances may develop some problems and perform erratically.

If your Pelonis heater keeps turning off, the following issues may be the culprit:

  • Damaged fuse/circuit breaker.
  • Malfunctioning thermocouple.
  • Faulty heating elements.

In the following paragraphs, I’ll explain in detail what you can do to resolve this problem yourself. Let’s get into it!

Tips to Fix ‘Pelonis Heater Keeps Turning Off’ Issue

1. Test the Heating Element

The heating element is there to make sure your heater can produce enough warmth to keep your house comfortable. Often, the heating element may have issues, which may affect the Pelonis heater’s performance.

A faulty heating element may cause the heater to overheat. Of course, that’ll cause many problems, chief among them being that the heater may switch off randomly. As we’ll explain later, your Pelonis heater automatically shuts off whenever internal temperatures reach the limit.

Testing the heating element doesn’t require a lot of technical know-how. Follow this handy guide to check the condition of your heating element:

  • Connect the heater to a wall outlet and check the heating element.
  • Make sure that the heating element radiates a bright orange color. A weak glow means that the heating element has reached the end of its service life.


  • Remove the heater from the power outlet and disassemble it.
  • Measure the resistance in the heating element with a multimeter — a high resistance is a sign of good health. If the resistance in your heating element has dropped, you’ll need to replace it ASAP.

Using any of these two diagnostic methods should reveal the problem with your heating element. And if you must buy a new heating element, make sure it has the same specs as the original equipment.

If this fix doesn’t help, continue to the next step.

2. Replace the Thermocouple

Thermocouples measure heat production in household heaters and prevent these appliances from running too hot. Your Pelonis heater likely has a thermocouple programmed to cut power if it detects abnormal heat levels.

So — you need to check the thermocouple next time your Pelonis heater switches off without warning. But don’t stop at the thermocouple; check other parts to know what caused the device to overheat. You can discover bigger problems by doing that and solve them before a bigger problem pops up.

3. Replace Faulty Power Equipment

If your Pelonis heater uses electricity, two things are necessary: a working power source and a functional heater cord. Any problem with these two parts increases the risk of your heater dying without warning.

How can you know if you have poor power equipment? You’ll know that your heater cord needs replacement if it shows small signs of fraying, burning, or melting.

Plug another device into the wall outlet to confirm if a faulty socket isn’t causing the problem. You want to look for any burn marks and unsightly stains around the socket. If such signs are visible, you need a new socket.

4. Check for Fuse Damage

It’s common for household electrical devices to surge with electricity on random occasions. An electrical surge often spells bad news because your devices can only withstand so much electric current.

Luckily, you have the fuse to protect your heater from total damage. Whenever the fuse senses too much electricity passing through the system, it automatically melts and forces the heater to stop operating.

You’ll need to disassemble your Pelonis heater to see if the fuse has anything to do with the problem. A rule of thumb is to check the fuse for signs of damage (melting, burning, etc.) and replace it as needed.

Fixing your fuse may not completely solve the problem. This leads us to the next DIY tip you can use for fixing the Pelonis heater issue.

5. Fix Malfunctioning Safety Systems

As with most heater manufacturers, Pelonis has automatic protection features on its heaters. These safety features have been programmed to shut down the heater during emergencies.

For example, have you noticed how the heater stops working when there’s electrical overload or potential overheating? That’s your built-in safety option working to protect the device from damage.

That said, your automatic safety feature is the first place to check when the Pelonis heater won’t stay on. A good place to start is the circuit breaker — make sure that nothing has tripped it. You can also inspect other protection equipment and reset them as needed.

An oft-ignored problem with safety features is faulty sensors. If the sensors are faulty, the protection systems will act on wrong information and shut down the heater even if it’s in good condition.

Some users have traced the problem to the carbon deposits on the sensor’s contact points. If you find something like that in your heater, clean it properly. Otherwise, you may have to repair or replace the sensor or safety system.
