Pilot light works fine but regardless of how long I hold down the light pilot light button, when I try and move the control to ON, the pilot light decreases then goes out and the heater does not light. I have installed a new regulator on my propane tank but that did not help.

Re: Heater won't light
YOU HAVE A BAD THERMOCOUPLE. IF YOU LOOK AT THE FLAME you should see a little match size piece of gold metel connected to a metal tube like then screwed into the gas valve. what happens is when you light the pilot, the gas heats up one end of the thermocouple and the other end changes that heat into microvoltage. the gas valve senses the microvoltage , knows the pilot light is lit then opens the main gas valve. when they go bad they cant send voltage to valve and th valve locks out. you always have to start at off. then depress valve button and turn to pilot and light it. hold button down 3 minutes then turn to full open or main the thermocouples are cheap, call supply houses or service companoies till you find one that will sell you one. unscrew the thermo couple from the valve with a little wrench unwravel the excess tubing , size of a pencil lead in diametor, then the probe part usually slids up through a spring like holder, note position of old sensor before reoming. get end half of new sensor into good pilot flame. reuae old retainers or new ones that come with new t couple.

You probably have a defective thermocouple. The thermocouple sits in the flame of the pilot, and the heat generates a small electrical current conducted back to the gas valve, keeping the pilot gas line open after you switch it to the "on" position. That's why you have to manually hold the gas valve depressed (on) during lighting in the "pilot" position, allowing the thermocouple time to heat up enough to generate its current. A defective thermocouple will not generate the holding current.
Turn the Gas Control Knob inside the heater compartment from OFF to PILOT. Push in the knob and hold it, at the sametime push the ignitor button (will probably be a Red button). Once the pilot lights, continue to hold the Control Knob down for one minute. Then ease off of it. If the pilot stays lit, turn the Control Knob to the ON position. The burner should light, if the Thermostat is set higher than the ambient temperature in the house. If the Ignitor button doesn't work, you can match light the pilot. Just be careful and follow the instructions above, once it's lit.
Sometimes it takes a few seconds for gas to reach the pilot. When you place the thermostat knob/gas control in the pilot position you must then depress it (push it down and hold it down). Wait a few seconds while holding it down, then press the ignitor button with your other hand while continuing to keep the thermostat knob depressed. You may have to hold the knob down and press the ignitor several times. You should see a spark at the pilot if the ignitor is working properly. Continue to hold the knob down for 30 seconds after the pilot lights, then release the knob, it will pop up & you can then rotate it to lo/med/hi and the heater will come on.,
Remove front cover,or just lower section if you can. they usually just need to be lifted up about an inch or so and pulled out. However some have covers that snap in place. After you remove cover locate gas valve. It should have a control knob on top with markings for on, off, and pilot. Set control to pilot. Follow lines from gas valve to burner compartment, one goes to main burner one ,small copper colored line is the thermocouple, other line is the pilot. Turn thermostat down as far as it will go. Make sure gas supply valve in line to heater is on and then depress pilot control , when you have pilot control depressed have a match or other small flame source close to pilot assembly. If it lights then hold down on pilot control for a couple of mins. Slowly release pilot control and if it stays lit turn gas control to on. Turn thermostat up to call for heat and burner should light. If pilot doesn't stay lit when you release pilot control then try again holding pilot down longer. If it still won't stay lit then thermocouple will need replace. Good luck. Thanks
Move the gas valve knob to the PILOT position and press down on the knob. You will be pressing down on a spring loaded safety magnet. Now light the pilot and keep holding down the knob till the thermocouple gets hot enough to produce electrical current and hold that spring loaded magnet in. This is your safety device. If the heat gets too hot the furnace has a fuse in line with that magnet. When the pilot stays lit by itself without you having to hold down the button then advance the knob to the ON position. Then go to the wall thermostat and turn on the heater.
You will first need to turn the control knob to pilot. Then depress the control knob button and hold it. Then press the push button piezo igniter several times until pilot lights or open pilot inspection cover and manually light pilot with match/lighter. You may need to hold the control knob for at least a minute. Then release the control knob and if the pilot stays lit then turn the control knob to on. If it does not light then repeat the process again.
hold down the pilot valve knob and turn the arrow to pilot position push down on red button to allow gas thru pilot tube hold down and light keep button held down for 1-2 mins while pilot is on to heat up the thermocoulple then release and turn knob to on position.
You pilot ignator is plugged.I take a small wire and run it in the hole every year and I also Blow the heaters out real well with air.THis has always worked far me.I need a phone number or email address to Pro Com because i'm having problems with a new one i just bought and I can't find the papework.Could you pleas eif you have this info email it to me
