Working on a Armstrong 2PGE30068P-1A late last night. Everything works until it trys to ignite gas..Gas valve opens and i am getting 24 volts through sparker wire,but no spark..I live 40 miles away from parts,wanting to make sure it is ceramic sparker...Thanks

    I did clean the sparker, but did not measure gap. What should be my voltage coming off my control board ? Thanks

I hope you are taking to the spark control board that you are checking power to. The spark wire itself usually has more than 24v. If you cannot see any visible spark when it is trying to ignite take the spark assembly out and clean it with some emery cloth or lite sand paper. Also make sure the pilot assembly is not plugged when you take the spark assembly out. Be sure the gap on the sprark assembly is set to a 1/4 of an inch if the gap is to big it will not spark and if it is too small it will spark but it will be to small to lite the gas.

    The voltage off the control board is to high for most meters sometimes 10,000v depending on the board check the bower going to the board if there is power to the board and no spark coming out then the board is most likely the culprit not the ignitor. Check the incoming voltage to the board.

I have a goodman gmp075-3 furnace, blower and igniter are working fine but not getting any gas to get furnace going


Check if 24 volts is being sent from the board to the gas valve, if not the board is nad and will need to be replaced, if there is 24 volts at the gas vlave terminals then the gas valve must be replaced.

Frigidaire furnace wont light pilot. we have replaced igniter and pressure switch


Gas valve solenoid have continuity? No continuity replace the valve
Getting 24 volts to the gas valve? No voltage from control board check fuse on control board.
Replace control board.
Any rollout switchs that are open and you won't get 24 volts to the gas valve.

Gas heater, everything seems ok, fan starts, igniter glows but gas valve wont open. what could be the problem


It could be a number of problems........ I will give you the most common ones. Did the gas get shut off..are you getting gas to the Gas Valve..... Is the gas valve getting 24 volts right at the end of the cycle of the igniter? If not then the ignition control board could be bad.. If the gas valve is getting gas and 24 volts then the gas valve could be bad. The manifold gas pressure may be to low... The gas burner itself may be dirty and not letting the gas to hit the Hot surface ignitor. Or the position of the ignitor may be to far or to close to the burner..... So you see if could be any one of these or a combination of them... Hope this help on your problem.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician Or HVAC tech to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.

My weatherking 90 furnace that is about 12 yrs old will not ignite the system works but will not ignite. The ignightor however glows hot. Thanks.


Hello, make sure the gas valve is opening and the burners are getting gas and verify that the gas valve is getting 24 volts.

When the thermastat turns on the furnace doesn't ignite the burners and the pilot light is lit. Everything appears to be normal, fan runs, thermastat appears to work properly.


You may have an open limit or a bad gas valve. Check and see if you get 24 volts to the gas valve, if you do then you gas valve has gone out.

No blinks normal running igniter glows gas comes on wont run


Check for 24 volts across the gas valve when Ignitor is glowing. If no, bad board. If yes, bad gas valve or blockage.
On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the igniter. The igniter will glow and you will be able to see it if viewed thru the small inspection port. Once the igniter gets hot enough, it sends a signal to the module opening up the gas valve (24 volts). Either a pilot will come on or the burner tube will ignite then spread the flame to all burners. Lastly a safety sensor will be looking for a certain temperature within a few seconds and the furnace will continue to operate and the room air blower will turn on in a minute or two.

What could go wrong? The unit will not run if there is no signal from the thermostat (bad thermostat or broken wire), the control module does not sense a signal from the thermostat (bad control), the inducer does not energize (bad motor), the pressure switch does not close (blocked vent piping, bad switch, plugged condensate hose), the igniter does not energize (bad control, bad igniter), the gas valve does not open or there is no gas (bad gas valve, broken wire, no gas), the pilot does not light (dirty pilot), the burner does not light (bad burner, plugged orifice, not enough combustion air), the flame does not spread to each burner (bad flame spreader, dirty flame spreader, more bad burners), the flame safety sensor does not detect flame (dirty or bad flame spreader, bad flame sensor, broken wire, bad control), or the room air blower does not energize (bad fan motor, bad control).

My York Stellar PLUS furnace (Model P2UDD12N07601C) will not stay on; The ventilator fan runs, the main blower runs, the igniter comes on for approximately ten (10) seconds and you can hear the gas valve...


Check gas pressure, inspect manifold & make sure there is not a blockage.Make sure gas is present and main gas shut off valve to furnace is on also check the knob on the 24 volt gas valve and see if it is in the on position , check the MV terminal on the gas valve to 24 volt common with a volt tester to see if you have 24 volts present, if you do have 24 volts at gas valve, replace valve. if you do not have 24 volts at gas valve check high limit control & roll out limits for a open circuit, Good luck.

Red light blinking continuosly meanig gas valve relay short how can I fix myself - furnance only blows cold air


You will need to check for 24 volts AC to the gas valve after the igniter starts sparking or glowing. If you have it but it does not open, bad gas valve and you will need to replace it. If you are not getting 24 volts after it starts glowing or sparking, you have a bad board.

On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the igniter.

I'm trying to start-up a Hayward H400 natural gas heater for my pool. It was brand new last season and worked perfectly. It keeps firing up for a little while (maybe 10 seconds on average) and then shuts...


if means ignition failure check that gas is on, check for fauilty igniter wiring or connections, inspect gas valve wiring measure voltage across gas valve during trial to ignition if 24 volt replace gas valve if no 24 volt replace control module
