You need to change the thermocouple on the unit.

pilot lite will not stay lite - 9a50546.jpg

First check to see if the flame is hitting the thermocouple when the flame is on when you hold down the button. If it is then remove the the thermocouple and replace with the same size. You should be able to pick one up at your local hardware store.

If when you replace the thermocouple the flame does not stay lit still you may have a bad gas valve.
Hope this helps and please rate this!

Pilot light on furnace went out. how to i re-ignite?


I have experience with coleman furnaces installed in mobile homes. There is a red switch on the gas valve. Some models require you to slide the red switch to the top and hold. Holding is allowing gas to the pilot. You have to stick a long match,grill igniter, to stick through the inspection hole (a little flap or door to see inside the burner area) and hold the match over the pilot while holding the switch upwards at the same time. Others have a pilot selection on the gas valve which you slide the red switch to pilot and push down and hold while liting the pilot. You may need help with holding the door open while doing this. If you can you can use the copper line for the thermocouple to hold the door open for you. Good luck

My propane fireplace pilot light wont stay lighted help


Most gas valves have a flame sensor, which is a metal bulb at the end of a wire. The pilot light heats this bulb, and the valve stays open because there's a flame. If the flame has been out, you'll need to hold down the pilot light button for as much as two minutes after lighting the flame to allow the flame to heat the flame sensor up enough to keep supplying gas when you release the button.

Heater will not stay lit after releasing button


Make sure your thermocouple tip is in the pilot flame and the other end is snuggly screwed into the control. Clean the pilot if not heating thermocouple. If pilot is heating tip thermocouple and it still goes out after holding the button down for 2 minutes, then your thermocouple is likely bad.

Sometimes when you turn a gas heater off for some time, if the source tank has been turned off, the line will bleed the propane and the line will contain mostly air. This is especially true if the supply line is long. In order to light the pilot, you will have to hold the pilot lighting button down for a while (a full minute or longer, depending on the size and length of the supply line) before pure propane arrives at the pilot light jet. You should keep a lighted lighter at the jet so that when the gas arrives, the lighter will light it. After the pilot lights, you will have to keep the button pressed long enough for the thermocouple to get hot enough to set the pilot to stay on. When it is hot enough, you should be able to release the pressed lighting button and the pilot should stay on. If it does, you should be able to light the heater. If the pilot jet never lights, gas is not getting to the regulator. If the pilot will not stay lit after a period of time waiting for it to heat the thermocouple, the thermocouple or the regulator may be bad and need replacement. :-)

Propane heater wont work


I'm not sure about that model, but I think you have to hold that button down for a minute or more to "prime" it.

I have a different model coleman propane heater that sits on the 20# tank. Mine is probably getting rusty, last time I used it I had to hold that button down for a long time.

I'm looking for a new heater now myself, as mine won't stay lit outdoors in much wind.

Unable To Keep Pilot Light Lit!


I have a Williams top vent gravity wall furnace (model 5009622) and I had the same problem. I had to take the cover off the furnace -- screw on top and two at the bottom (open the access door and there is one screw on each side) to get to the reset button for the vent safety shutoff system. On my furnace it's on the left side toward the top of the unit. I pressed the little red reset button and it's been working ever since. If your furnace is properly installed and doesn't have bird's nest in the chimney, it should work fine. Good luck!
