The recommended reset, turnoff oheater on thermistat, disconnect power and turn off Gas Switch and then back on , turned power on and turn thermistat switch.
There are two fan motors on your system. One is the Blower Motor that blows the heated air thru the vents in your house, and the other Is called The Inducer Combustion Motor. It is connected to the flue pipes. It is located inside the furnace and has a rubber hose connected to it that attaches to the pressure switch.
On a call for heat I need to know if the Inducer Combustin Motor comes on.
You will need to remove the top door of the furnace.
Does it come on?
yes, it comes on, but gas is not lighting, and no smell of gas
Does the igniter attempt to ignite? sparks or Glow coil?
No it doesn't glow or light
Remove the rubber hose, blow in it to make sure it is clear, make sure there are no tares in it. Then use a paper clip or nail to clean the connection at the inducer combustion motor. Make sure it is clear. Reattach hose. Then attempt ignition.
If that doesn't work, remove the two wires attached to the pressure switch and hold them together metal to metal then attempt ignition. Make sure the wires are attached together metal to metal.
Tried that removed hose blew into it, no debrey, even put two wires together from swiitch, no ignition
When you attempted this, did you smell gas? If so, your ignitor is bad.
put two wires together, no gas smell, no light, checked switch. ohmed it out it deplayed 0 ohms. XXX-XXX-XXXX. This has me stumped
When you put the two wires together on the pressure switch, Were they metal to metal?
Yes they were metal to metal
Did you have the switch on the furnace panel doors pressed In? While troubleshooting, place a piece of tape over this switch to hold it in.
The bottom door was left on it had the switch , the top secton had the combustion motor switch and i did put metal to metal on the leads. I found a copper tubing with what looked like a probe on the ground from a long ago previous maint effort before we bought the bouse 10 years ago. I signed up for the monthly membership
I would recommend you change the igniter. When you put the two pressure switch wires together metal to metal, It should have attempted ignition, but it didn't. I beleive the igniter is bad.
