Dust build up inside the pilot light burner assembly. A clean pilot makes noise and has a blue flame when it is burning. A dirty pilot has a quiet and smaller flame with an orange tip.

Look at the burners,there will be a pilot.It should be in the front of the burners,in the middle or at one end.Find it first.It will be a small hollow tube.This pilot does not put out a big flame,so don`t worry about it gusshing a flame out.you will want to be ready with a match or a long lighter.A short lighter will do.Turn the knob to pilot.Push down on the knob,and light the pilot at the same time.Now when you do this,hold the knob down,and don`t let off the knob.The thermocouple has to heat up and sense the flame.And it will take about 30 seconds or so.When the time comes to release the knob,do it slow,and watch the flame,if it tries to go out,push it back down for about 20 more seconds.If it will not stay lit,you will have to make sure the thermocouple is touching the flame.The thermocouple has to be in the flame good to heat up.A small steel,or cooper tubing cut off,short,maybe 1/2 inch,can be dropped over the thermocouple to make the flame touch it,and accomplish this task.If the pilot will not light when you push down on the knob,then bleed the air out of the gas line,by holding the knob down far a while,and coming back to it ,to make sure there are no gas fumes around.It won`t be that much gas,just a little.But it is better to be safe.If I can help any more please let me know,and if this was at all helpful,please let them know,thank you.

Thermocouples are kind of generic. If you remove the one on the heater, you can take it to your local hardware store and match it up. The new ones usually come with adapters for the three main ways they attach. The only thing you really need to make sure of is that is the right length.

Replace the temperature slecting switch.

Open the little door panel with the knob and turn up the thermostat knob. Down on the front. If you need further help, I’m available over the phone at https://www.6ya.com/expert/craig_3fa289bf857b1a3c

Would it work - yes.
Should you - NO! Not even temporarily! The vent switch is there to save your life!

believe it or not, the propane tank may be too full. The vapor space is taken up and you have very little vapor. Run some warm water over the tank. The garden hose may be enough but if you get no frost line the water will need to be warmer. The warm water causes the liquid fuel to turn into vapor. Do not use boiling hot water. Another thing is oening the valve. Most propane tanks have safety valves. If the gas escapes faster than a normal rate, the valve closes. Open the valve slowlyand lt it burn for about 10 minutes before opening the valve further. It will get better as the fuel is used up and the vapor space in the tank increases. In real cold climates a heater blanket, sleeve is used tho keep the bottle warm. The vapor also creates the the needed pressure to move the gas through the system to the burners. Good Luck-Ned_

You better increase your insurance if not you can I ?? you never bypass anything with the explosive force that 5 gal cyl has in it! I wouldnt run something like that or be anywhere near it unless I was freezing to death anyways!

Well, I just went out this morning and worked on the heater after it would not light last night. Turns out that a spider or moth set up camp in the pilot light intake housing and plugged up the two small mixer holes that pull in air for the pilot light. This would explain the 'yellow-flame'. I took a punch awl and some compressed air and cleaned out the hole, then re-installed the cover and knob. Lastly, I turned and depressed the knob and the pilot light ignited almost instantly, stayed on when I let the knob up, and the heater turned on normally after that. Good luck, I hope this helps.

Try this website for instructions on how to fix this problem

If the heater has been sitting for awhile, an insect or small spider may have set up house inside the gas controls and this needs to be cleaned out. The holes are tiny and doesn't take much to block. Try blowing out the orifices with a compressor.

I would say that the lines still need to be perged. This some times takes a few times to get it going . If it has set for a long time or have run low on gas.it only takes a little air pocket to stop the works. Ask the man back. $125.00 is a lot of doe for no go. DFD

Bad flame sensor. Try to clean it with some steel wool

Try purging the air from the tank.

Thanks for using FixYa...

check ur safety flame sensor proubly a thermocouple try replacing it.

Probably a venting problem! Can be very difficult to diagnose and repair'

It can be shut off, but do not just blow it out.
