Turn Thermostat to call for heat (here click)from the t-stat calling. I do not here the multiple click (ignitor)and then the flow of gas. I have a Honeywell VR8204M electronic gas valve. I have votage coming from the control board "PV" to my electronic valve. My question is do I have to change the entire electronic valve or should check some other things first.

That particular intermittent pilot gas valve uses one of three ignition control modules; S86F, S8600F, and S8610. Check the pilot assembly and look at the flame, could be a weak flame, dirty or clogged, if its not lit or weak, you’ll hear a constant buzzing or “sparking” sound, this will lock-out the gas valve. If you hear nothing at all, start with cleaning or replacing the pilot assembly, then check the ignition control module.

Hope this helps

Wiggle wires, it could be something as simple as a loos connection. If your getting power to valve and it's not opening your valve is bad. Also check your limits somethimes all limits are connected and one broken one will throw the system off.

It doesn't want to shut off and we have no heat?


when you say it doesnt want to shut off i'm guessing you mean the fan. the fans run on a timer when the thermostat calls for heat it will come on 90-120 sec.later. turn your t stat down below room temp and it will shut off in 30-60 sec.your ignitor is most likly bad. turn your t stat back up and look at it. it should glow. furnace will try to light 3 times,you may hear the gas flow for 3 sec.during this cycle. if no glow good chance that is your problem and you will need to replace it.be carefull it is very brittle and breaks easy if tapped. be sure to turn the t stat down again or the fan will start running again.

I have a Arcoaire Gas Furnace (Model# GNJ100N12A1), that will not fire up. It has a White Rogers Digital Stat. First the Stat seems to be faulty, since it reads 70plus in a house that has a temp of 30...


Sounds like a faulty board. shut the power to the furnace off for a minute then turn it back on. Make a call for heat at the thermostat. The inducer should start and close contacts on a pressure switch . Once pressure switch closes the hot surface ignitor should glow red. Then the gas valve will open when the gas valve opens you should get fire till the stat is satisfied. If your concerned it is the jump out r to w on the board this will eliminate the stat. If you to reset the rollout switchs 3 timesyou're getting flame rollout and you either have a cracked heat exchanger or blockage in the exhaust piping or a bad inducer motor. Keep me posted with what you find!

I have an armstrong air ultra v, the ignitor switch or the blower won't come on, we ran the tank pretty low last year, so i'm not sure if we ran out, but we just filled our tank' any suggestions because...


First make sure that your thermostat is turned to heat and auto settings. Then turn up t-stat to where it should be calling for heat.If nothing happens then make sure you have power to heater, gas valve is turned on and blower compartment door is securely latched. If still nothing turn t-stat to fan on and the blower should come on and run until you shut it off. If it does this then you know that you have power to furnace and that the blower works.After you are sure that you have power then remove thermostat cover from base. If stat wires are connected to front of base then disconnect red and white wires and temporairly touch them together. This should send power to your furnace and start the ingnition cycle. If this works then replace thermostat. The sequence of events in the ignition cycle are t-stat calls for heat, induced draft motor comes on and runs for about 20 seconds,then ignitor comes on and lights pilot,then burner lights for 1-2 mins and then blower comes on. I would start at the t-stst and work my way through it. If I can be of any help please ask. Thank you

I'm still having the problem with the heat Some times the dryer heats for a minute and sometimes for 3 seconds, i replaced the coils and the hi-limit thermostat .I hear this clicking so i know the ignitor...


Hi, If you are having problems with your gas dryer not heatingthe most common problem is that the ignitor goes bad. Even though it glowssometimes it is still not working properly. check out this gas no heat tip.... You did not mention the ignitor... and it can also be the cause of problems... I would change it and see what happens...
BTW... did you change the operating t-stat??? It also could be the problem...

This sounds like a pressure switch problem,alot of the time condensation gets into them and cause the problems you are describing...if you can take them off and shake upside down untill water is out of them...also check to see if anything is biocking intake or exhast
