Hi, my name is ***** ***** I'll be assisting you with your question regarding your Furnace. I apologize for the extended wait time you experienced, I've only just come online now and would like to assist you with your question. If the induction motor is running but no flame is being produced it can be a variety of different problems. Safety tripped, failure to recognized induction motor running, bad board, bad gas valve, no gas, etc... Are you wanting to try and fix it yourself?

the other day had a similar situation , changed thermostat setting switched fan from on to auto changed settings back to previous and heat came on. didn't work this time. I checked the terminals on the thermostat (loosened and retightened)
Customer reply replied 5 months ago
I'd prefer this method, then I've got a record.

Ok, let me try to pull up the schematic of the system.

I dont seem to have that unit on file. Can you locate the control board and see if it has a LED?

Ask Your Own HVAC Question
Customer reply replied 5 months ago
can't see a control board, there's a honeywell module #s8600h

Ok, that module is the control board. It just has a plastic shell. Is there a LED visible?

no

Ok, Do you know what an Inducer motor is?

Ask Your Own HVAC Question
Customer reply replied 5 months ago
Is that the motor/fan for draft?

There should be a vinyl/rubber tube connected between the Draft motor housing and the Switch

can i send you a picture?
Ok, you don't have pressure switch. Yours is the grey box on top of the inducer. It's a centrifugal switch.

Customer reply replied 5 months ago
I replaced that motor a few years ago

Ok, that should be fine. On the metal plate, there is a switch with a little red button. Press on it and see if it clicks.

Ask Your Own HVAC Question
Customer reply replied 5 months ago
it does

Ok, put the door back on and test the system. Please do not run the system with the door off, Its dangerous.

Ask Your Own HVAC Question
Customer reply replied 5 months ago
after I pressed the red button, I could hear rapid clicking. ok the door is back on but still no heat

Ok, the rapid clicking is the Spark igniter on the pilot Assembly. Its sounds like you are not receiving power to the gas valve or you have no gas. Are you on Natural or Propane?

Ask Your Own HVAC Question
Customer reply replied 5 months ago
natural

Do you have a volt meter?

Ask Your Own HVAC Question

Ok, turn off the gas at the cut off valve beside the unit. There are 3 terminals on the side of the Tan gas valve. 1 black wire, 1 white, 1 brown. Turn the system on and check between black and brown. and white and brown while its clicking

mv - pv =14vdc

Need to check MV to MV/PV

and PV to MV/PV

MV is main valve

MV/PV is Common

PV is Pilot vavle

Ask Your Own HVAC Question

My colors might have been off. You should only have 24-28v between PV and MV/PV while its clicking which should activate the pilot valve to release gas.

Ask Your Own HVAC Question
Customer reply replied 5 months ago
pv-mvpv=27vac
Customer reply replied 5 months ago
mv- mvpv=0.2vac

Ok, if you have spark (clicking) and 24v+ to the gas valve then there is a failure in the gas valve.

Ask Your Own HVAC Question

If your not comfortable with doing gas work youll have to hire a company to replace it for you. If it something you think you can do, youll need to order a replacement valve.

Ask Your Own HVAC Question
Customer reply replied 5 months ago
It's definitely 27vac not dc.

Correct, HVAC does not use DC except for Very Few relay found in Carrier.
