The heater won't stay lit

I have a propane wall mount heater and the pilite light stays lite but when you turn it up to kick on the burner lights and will stay lite for a few seconds and kicks off and the pilite light goes out too. Any suggestions on how to fix it, It is only 2 months old. our heater won't stay lit - we hear a click right before it goes out.

SOURCE: the heater won't stay lit

Hi Tiffany,

When a gas applaince goes off it is usually because of a safety precaution. When the unit dies not detect a flame, it will shut off so that it does not fill with gas and cause damage. A flame sensor is a metal toothpick type item that is in the flame area and could be dirty, although it is two months old, this may be another problem.

But if it is charred, you will need to clean it using a soft cloth or even a well used dollar bill. Don't use abrasives, it will take the coating off of the part and cause it to wear faster.

If you are unsure, below is a link to the manufacturers website, you can get the technical information there.

Pilot won't stay on


Burners don't have anything to do with the problem of pilot not lighting. Is the problem that flame will not 'stay' lit? Or you can't even get a flame to ignite? If former: possible bad pilot generator or bad gas valve. If latter, possible bad gas valve or no fuel to ignite.

It sounds like a thermocouple has gone bad. this is a very common problem with gas powered things ie; water heaters, furnaces, hot tubs. The telltale sign is when you release the pilot light button it won't stay lit. This is a safety feature and is relatively inexpensive and easy to repair.

Pilot lights (not always) but gas will not flow into burner


First Clean the ignitor assembly and make sure the flame is reaching the flame sensor strongly.

You may need to replace the flame sensor.
