Mr. Heater problem

[Haug Hunter]

I'm having problems keeping my mr. heater burning without keeping the button pushed in. I replaced the thermocoupler thinking that was the problem. Now it will stay running for about 1 min. and then go out. Any suggestions?

I had this problem this weekend. All I had to do is bend the thermocupler towards the heating element a little bit. If the thermocupler doesn't read enough heat it will automatically shut off (safety feature to prevent unburned gas from accumulating). Try bending it in just a little bit and see if that helps.

If the thermocoupler thing doesn't work, here is another simple thing or two to check. If you are using a new 20# tank that was just filled, remove the heater and open the valve on the LP tank for 10 or 15 seconds. Over filled tanks push liquid gas up into your heater, causing it to sputter out. Always check the O-ring on the heater part that goes into the tank valve. I replace mine every year. Two simple ideas for ya.

those are all good ideas. the important thing is , are you getting enough gas for the pilot. if i remeber right, it should be about 1/2" to 3/4" long and a blue flame. there is a small bug thats attractide to propane. it builds small nest in the lines and fittings. looks like a fuzz ball. they can plug the lines and reduce flow.it happened to my gas grill. carfull not to put thermocoupler to close to pilot.
