Solution #5 Clean Air Filter
The air filter is one of the important components that circulate the air.

Solution #6 Replace Thermal Fuse
After trying every method from the guide, if your heater still keeps shutting down, then there are high chances that your heater’s Thermal Fuse is blown out.
The thermal fuse prevents the heater from overheating, but when it gets faulty, it’s unable to handle the heat which results in turning OFF.
- Replacing the heater’s thermal fuse is all that can fix the problem!
Here is how you can replace the heater’s thermal fuse:
- Unplug the heater from the Power Source.
- Flip over the heater and place it on its head.

However, there is one more thing…
Solution #7 Inspect The Thermostat
The Thermostat malfunctions often lead to incorrect device assumptions.
If your heater still turns off, regardless of what you attempt, it’s possible that your heater thermostat is faulty and unable to recognize the temperature settings.
Perhaps the heater is turning off just for safety.
