Pelonis Heater Keeps Shutting Off [Reasons + Solutions]

Your Pelonis heater keeps shutting off due to one or more reasons like a faulty heating element, bad thermocouple, dirty air filters, bad or weak power supply, tripped circuit breaker, blown fuse, malfunctioning safety function, and broken thermostat. 

Keep scrolling for solutions to these problems and fix your heater ASAP.

Why Your Pelonis Heater Keeps Shutting Off

We’ll now take a detailed look at the causes. Also, we’ll show you the easy and simple solution to each problem.

1. Faulty Heating Element

A faulty heating element can be why your electric heater turns off by itself. The heating element ensures that your heater produces enough heat to keep your home pleasant.

Frequently, the heating element will develop problems, affecting the Pelonis heater’s performance.

The heater may overheat due to a malfunctioning heating element. Of course, this will result in a slew of issues, the most serious of which is that the heater may turn off at any time. 

When the heater’s interior temperature hits the limit, your Pelonis heater automatically switches off. We’ll explain this in detail later.


First, you’ll need to find out whether this is what is causing your heater to keep shutting off. Testing the heating element is necessary to conclude. 

You won’t need much technical knowledge to conduct this test. We’ll discuss two methods you can employ to carry out the testing.

Method 1:

  1. Check the heating element after connecting the heater to a wall outlet.
  2. Inspect to see if the heating element emits a strong orange glow. The heating element has reached the end of its service life if it emits a feeble glow.

Method 2:

  1. Disconnect the heater from the power source and take it apart.
  2. With a multimeter, check the resistance of the heating element; a high resistance indicates good health. If your heating element’s resistance has fallen, you’ll need to replace it right away.

Using one of these two diagnostic methods, you should be able to figure out what’s wrong with your heating element. If you must purchase a replacement heating element, be sure it meets the same specifications as the original.

2. Bad Thermocouple

Unlike a circuit breaker, which is located externally and controls the power supply to a whole home or structure, a thermocouple is a small device located within the space heater itself.

Thermocouples monitor heat generation in residential heaters and prevent them from overheating. 

A thermocouple in your Pelonis heater is likely configured to shut power if it detects abnormal heat levels.

If the thermocouple detects an unusual rush of energy flowing through the space heater, it will turn it off every time you try to turn it back on, and it will remain off until the internal problem is located and fixed.


Check that the thermocouple is in good working order. You can do that with the help of a multimeter. If the thermocouple is defective, you’ll need to replace it.

3. Dirty Air Filters

If your space heater’s air filter is dusty or unclean, it may shut off repeatedly. Filthy air filters reduce the amount of airflow that oscillates through the heater, limiting the device’s internal capacity to cool itself both during and after the operation.

The air filter will emit an unpleasant odor if it becomes clogged with dust or debris. Your air filter’s odor is the first sign that it needs to be cleaned. By smelling your air filter, you can tell if it needs to be cleaned. 


Here’s how you can clean Pelonis heater:

  • Remove the heater from the power source and allow it to cool entirely.
  • To remove loose dust, use a duster or a microfiber cloth to wipe off the heater.
  • To get rid of dirt and grime build-up, spray the filter with compressed air.
  • You can gently suction dirt from small cracks with your vacuum’s brush attachment.
  • Before turning it back on, clean any dust from the front and back of the heater.

Some heater models may require you to first remove the filter. After it’s out, you can move on to step 3.

4. Bad or Weak Power Supply

A Bad or weak power supply can be why your Pelonis fan heater keeps turning off. If your Pelonis heater is powered by electricity, you’ll need two things: a working power source and a working heater cord.

Any issue with these two sections raises the likelihood of your heater dying suddenly.


How do you tell if your electrical equipment isn’t up to par? If you notice little signs of fraying, burning, or melting on your heater cord, it’s time to replace it.

Check whether the problem is caused by a faulty socket by plugging another device into the power outlet. You should inspect the socket for any burn marks or unattractive stains. If you notice any of these indicators, you’ll need a new socket.

5. Tripped Circuit Breaker

Circuit breakers are used in many homes across the world instead of fuses. In a typical modern home, a single grey box holds several switches that are perfectly lined up in rows, with a single primary breaker at the very top.


Check the circuit box in your home to see whether any of the switches have been tripped. If this is the case, turn it back on and try the heater once more. If the problem persists, it could be due to a power outage. 

Different circuits are usually connected to different levels or rooms. You should try to utilize fewer heaters at once or distribute them across multiple circuits.

6. Blown Fuse

Thermal fuses are buried snugly inside the tough plastic casings of most modern space heaters. A thermal fuse is a small device that protects the rest of the heater’s components from overheating by blowing out or melting when the heater overheats.

The reason why your space heater keeps shutting off can be a blown fuse. When a space heater fails in any way, the thermal fuse inside the heater is usually the first line of defense to keep the equipment from failing.


If you believe your heater has a blown thermal fuse, you’ll need to disassemble it with the necessary tools, such as adjustable pliers and screwdrivers with numerous heads.

Then, you’ll need to remove and detach any clips, fasteners, or screws that keep the exterior and inner portions of your heater together.

After you’ve completed the disassembly, look for the thermal fuse and see if it’s burnt, melted, damaged, or broken. A blown fuse must be replaced with a new fuse that meets the same criteria as its predecessor.

7. Malfunctioning Safety System

A malfunctioning safety system can be behind your Pelonis space heater not working. The auto-safety shut-off is standard on all newer space heaters. What is the purpose of this selection? It’s easy to understand. 

By tipping over, overheating, or malfunctioning in any manner, little sensors nestled between the space heater’s components will be activated, instantaneously shutting off the heater.


Although this feature can be disabled, it is recommended that you figure out what is causing the auto-safety trigger points in the first place.

The sensors may simply be alerting you to the possibility that your device is no longer capable of properly generating heat and is now posing a safety or fire risk.

Other times, the sensors themselves may be defective, causing your gadget to frequently turn off. In this scenario, you’ll need to contact a heater service technician to either replace the sensors or fix the existing ones till they’re in good working order.

8. Broken Thermostat

The thermostat, like a thermocouple, is found inside your space heater. A thermostat, unlike its contemporaries, works as a temperature regulator for the heating system and is typically configured to your preferences.

The thermostat, on the other hand, can turn off the space heater automatically if it overheats or if the core temperature of the heater exceeds the manufacturer’s recommended temperature range.

As a result, a melted, damaged, or broken thermostat may be the only thin lifeline that keeps you and your family safe.


A thermostat can be jostled loose from its contact points as a result of a manufacturing flaw or if you accidentally knock over your heater.

Unless you unscrew your heater and readjust the location of your thermostat back to its proper position, the space heater will continue to shut off. Any damages to the thermostat will necessitate the thermostat’s replacement with a new one.


How do you reset a Pelonis heater?

There is no Pelonis heater reset button. So, you can’t reset it. However, there is a safety shut-off switch in case of the heater tips over. These heaters heat up quickly and contain a thermostat that allows you to control the temperature.

How long can you run a space heater?

Modern developments in space heater technology allow space heaters to be left on for extended periods of time. If you have a higher-end heater, you can easily leave it on for 10 hours or longer.

Is it OK to run a space heater all night?

When sleeping, never leave a space heater on. Although modern heaters have built-in safety mechanisms, you should never leave a space heater on overnight. Whether you have a gas or electric heater, it has an element that can get hot enough to start a fire, which is why you should switch it off at night.

Can I use a heavy-duty extension cord with a space heater?

No, an extension cord should not be used with a space heater. The enormous currents drawn by space heaters are too much for most extension cords to manage. Small, low-quality extension cords, in particular, are prone to catching fire. Don’t put your house in danger. 

Can an outlet catch fire with nothing plugged in?

When the breaker is turned on, an outlet always has power, thus it can spark a fire even if nothing is put into it. A turned-off light fixture, on the other hand, is extremely unlikely to ignite a fire.


It can be a pain to maintain your heater properly but doing so can save you hundreds of Dollars in servicing and part replacements. It is always better to prevent a situation than scurrying to fix it later. 

We recommend you hire a licensed electrician if the solutions are complicated to perform by yourself. There’s no point in risking your heater.
