I had similar problems with a older Reddy Heater. I bought a 0-15 lb. gauge and removed a plug on the control end of the heater. Turn on or plug it in and set the fuel line pressure as listed on the data sheet (also listed on the heater).

IMPORTANT. This type of heater will not light if the oxygen level is below safe limits. You need more that 14% to support life. Normal is 21%.

Restart the unit as soon as you see the inducer fan on jump the 2 wires the pressure switch. Your burner should stay on and go through it sequences. If it go through it that pressure switch need replace and make sure your inducer pull under the vaccum of the pressure switch.

Have electtric forced air 40.ooo, btu unit. have 10 psi regulator. am useing tank hookup from grill.wont stay lit.


I hope & pray, that the grill tank is not indoors with the heater. In any event, if you're using a grill regulator too, it's not going to provide the 11 to 13 water column inches of pressure that is required for 40,000 BTU's. That's why the heater wont stay lit. Nor, is it going to burn very long, as that grill tank only holds 2 gallons of gas

This is a gas appliance that is safe when installed and operated properly. Don't try to jury rig something that could come back to bite you in the end. Injuring or killing you and your family.

Have a Goodman GMT070-3B which the vent motor seems to be sticking. I took apart and cleaned the brushes and reassembled. The furnace will come on only after what seems like the vent motor comes up to...


The whole assembly must be replaced.

The sequence of operation is -

Combustion fan purges the heat exchanger. A pressure switch verifies combustion air fan is running. Usually a 30-45 second purge before the hot surface ignitor glows, or the spark ignition starts.

Gas valve opens after 10-15 seconds and main burners light. Control board monitors for flame and shuts gas valve after 2-3 seconds if main burner does not light.

If burner does not light, some boards repeat this for 3 tries, then locks out and is reset by cycling power.

Air blower comes on after another 30-45 seconds after main burner ignition.

Times may vary based on the specific controller board. A flow chart and timing sequence should be located somewhere on the unit, usually in the fan compartment.

sounds like your thermacouplar is going out and needs replaced. Sometimes these will act like they are working fine , but when the pilot stays on for awhile and later goes out it is a sure sign that it is bad

Old coleman dome heater wont light


sounds like your feed tube might be partially plugged, or the orifice, you will need to disassemble the unit and clean it, normally a good dose of high pressure air will clear the tubing and orifice, check the tank too to see if you have any de-bree in it, hope that helps.

Wont stay lit after 20 min with blower on


As a licensed plumber I will recommend now that you don't touch the heater. Gas is dangerous and leaks aren't easily found.

Everytime a gas heater is serviced the tradesman needs to do a gas check to see if all is working well. There are too many things that can go wrong, from a small gas leak to burnt gas leaking, all of which are lethal.

I can tell you how to fix it, but I won't, because it is too dangerous.

Getting a repair man will cost you, but not getting one may cost you your health or your life.
