Heater wont ignite

Heater goes through it cycle but ignitor wont glow. Replaced ignitor/pilot assembly.no effect. pulled plug on ignitor and tested for power to ignitor on gas valve pins. I can get 25 volts on one pin if I test to ground. If I test to the two pins I dont get power. I dont have the manual for the codes the valve is flashing. If you know whats wrong or can send the codes it would be appreciated. send to mertenshubert@hotmail.com. Thanks.

Can you give us a hint as to a make and model? Check the reverse side of the access panel within the wiring diagram for diagnostic codes.

Payne 383KAV heater. Gas valve won't open to fire heater.


Being as how you changed the gas valve, make sure the arrow on the bottom of the gas valve is pointed towards the burner. Check for 24 volts at the common and main valve terminals on the gas valve when the thermostat is calling for heat...terminals MV and C. You will only have 24v there if the flame sensor senses flame... either pilot flame or main gas. You coud have 24v there without gas flowing or flame if is is a thermocouple standing pilot system and the gas valve is not in the 'on' position. But standing pilot systems usually do not have flame sensors.

With a flame sensor in the system, you have to have either spark ignition or glow coil ignition. If its spark ignition check for 24 volts at the pilot valve and common terminals on the gas valve WHILE the ignitor is sparking. That would be PV and C. The ignitor should spark and 24v should be on PV and C for 30 seconds to a full minute without ignition if it is a spark-to-pilot system.

If you have a glow coil, it will energize and burn bright orange for a minimum of 30 seconds BEFORE the main valve is energized. Then MV and C is only receiving 24v for approximately 5 to 6 seconds. This gives the flame sensor the time to prove the flame....if it does not prove flame, the system shuts down.

Cozy gas wall heater won't ignite, pilot light is on


There are two types of igniters, spark-type or glow heater. The glow heaters wear out and crack or break and the spark-type spark gap gets fouled or dirty. Both could have electronics problems that drive the glow heater or spark systems. The Filtrete thermostat is not the issue. While rapping the unit makes the glow igniter come back together to glow again.

Sometimes when my gas plaque infrared gas space heater comes on a ball of loud flame bursts out in front of one of the plaques instead of lighting up the plaque. What causes this only occasionally? How can...


It sounds like a delayed ignition- and YES!-- that could be dangerous if something flammable was nearby, and no one was around to make sure the fire did not start something int he room on fire!

Trouble shooting delayed ignition:

Does this heater use a glowing ignitor to ight?

Or a standing pilot?

Or a spark?

I suspect that whatever is supposed to light the gas burner, is not in the path of the first gas release, (when the gas valve Opens) and so it takes a bit for the gas to build up, and finally get around to the source of ignition-- and then WHOOSH!!-- all that extra gas ignites!

Can you see the ignitor as it goes thru its first firing cycle-- what do you notice about the ignitor?

~~~~~~~~~~~~~~~~~~~~~~~

Something to consider:

What prevents it from filing the room with gas, before it ignites!

Sounds mighty dangerous to me!

Pilotlight is not igniting. I have it in the on position but it is not on and hence not igniting the ga. I would like to know what I need to do to get the pilot light to light


From what I just read online your heater uses a hot surface igniter to light the pilot. Turn the heater off. Give it a couple minutes, maybe 10. Then turn it back on. It probably goes through a purge cycle first then tries to light the pilot. You should be able to see the hot surface igniter glowing red somewhere close to the pilot. If not the igniter may be bad. Let me know what you see.

The fan works, no spark, have replaced ignitor assembly checked the high limit switch with ohm meter, room temperature switch is closed.


check for 24 volts at ignition module n pull the wire that provides the spark off the ignitor n see if it tries to arch or spark. your electrode on the pilot assembly might not be arching onto the hood of the pilot assembly. good luck!

Goodman gmnt100-4b wont ignite


listen for the gas valve to click on,,,if you do not hear it clicking on u could have bad gas valve,,,if it is smart valve which was around about 4 years ago they had major troubles and most where dead on startup. if it is clicking on than you might have something in the pilot tube or moisture in the valve,,try banging on the valve some ,,sometimes that will break it up and let it flow past if do right after it clicks in..might have to pull the pilot tube and blow out,,,sorry just dont have enough info at moment for lock down diagnoses,,good luck

Timing off?


it sounds like you are not getting gas out the of the pilot assembly.If you take the 1/4 gas line off of the gas valve and try to blow through it. If you can't then the orifice is plugged. If you can blow throw it then i would say that the gas valve is bad.do you have propane or natural gas. If propane then i would say pilot orifice is plugged.
