Cause 1: Dirty Pilot

The pilot keeps your heater ignited. If your heater pilot is dirty, it won’t light. So a dirty pilot can be the culprit behind Mr Heater not staying lit. Carbon, oil, spider web, and other types of debris build-up can be why the pilot light is not working. And as a result, turning off the heater as well.

Cause 2: Improper Draft Positioning

The draft allows air supply in the heater system. The heater works with the help of this air. But if there is too much airflow, then the heater will not stay lit. Excessive air will blow the fire out.

Cause 3: Dirty Thermocouple

A dirty thermocouple is another culprit behind your mr buddy heater keeps shutting off. Thermocouple signals the heater gas valve when to open and when to close. A dirty thermocouple will fail to do it. It will signal the gas valve to close when it is not needed. As a result, the gas supply will stop, and the heater won’t stay lit anymore.

Cause 4: Faulty Gas Valve

The gas valve supplies the fuel in your heater. Your heater doesn’t work without this fuel. And this is precisely what happens when the gas valve is faulty.

Cause 5: Dirty Pilot Orifice

The pilot orifice controls the flow of the gas to the pilot. You already know that if your buddy heater pilot won’t light, the heater will not stay lit. Again, if the pilot orifice is faulty, it will prevent the activity of the pilot. So basically a dirty pilot orifice will eventually cause the whole heater to shut down.

Cause 6: Faulty Flame Sensor

The flame sensor signals the heater to function appropriately. It reads the atmosphere of the heater and sends commands to the heater system. The sensor will read wrong signs if it’s dirty. As a result, it will command the heater to turn off. This is the same as the heater not staying lit.

There are times when the pilot tube on your propane gas heater becomes dirty. You should clean these tubes regularly because dirt and debris will get stuck in between them. You will need to check the pilot flame of your heater through the small window located near the knob.

3. Damaged Thermocouple

If the thermocouple on your Mr. Heater doesn’t detect the flame, it will deactivate the pilot light. A thermocouple is a safety feature that automatically shuts off the gas when it detects any fire. That allows the heater to prevent any gas from leaking. In many cases, the thermocouple on the heater is moved too far away to detect the flame.

4. Faulty Spark Electrode

If the pilot light for your Mr. Heater will not stay lit, there could be an issue with your spark electrode. If the electrode doesn’t produce a spark, you should check to see if it is broken. Or you may need to replace the Oxygen Depletion Sensor.
