Check the relay
the primary should have a low resistance
there should be a distinct click when 24 volts is applied to the primary
the secondary should be conductive when the primary is energized (contactors can corrode)
not a solution something to check

Combustion blower motor runs all the time


I'm assuming what you call a combustion motor is actually the idm(induced draft motor) which is the 1st action in a gas fired furnace, clearing any residual fuel from heat exchanger then forcing the flue gas to the outdoors. This IDM is controlled, normally, by the furnace control board(circuit board). May need a new board.

What could cause carrier fault code 42 besides bad inducer


Could be several causes.
1. Blockage on piping
2. Water in inducer housing slowing down inducer impeller
3. Condensate trap for furnace clogged up.
4. Inducer motor going bad.
5. Leak in vacuum hoses or not connected.

How do I wire a induce fan motor


Induced fan motors on older units are wired through the high limit safety on the stack - in series. When the furnace calls for heat, the induced fan motor comes on and after a time the furnace will light.

Older units have a temp switch in the stack that rotates to bring on the burners and blower motor. . When there is a call for heat, the induced draft fan motor comes on and then the burners will light.

After the heat exchanger is warmed up the limit switch will bring the blower motor on. That's basically how it works - there are two circuits - one for the induced draft motor and the burners and the other for the blower and high limit.

New units have a plug on the board you just plug in.

I have a carrier furnace the control board keeps coming up with differ t led coxes ifiI reset it it works a couple times then flashes a new code had four different codes come up so far 21 22 31 34


Have to know the model and serial of the furnace.
locate code list usually inside or on the back of a door.
Operation sequence= call for heat--inducer blower motor--makes pressure switch--signals board to bring on hsi--after a set time gas valve opens and you have ignition--main blower motor comes on after a set time

did you check the hose from the inducer to the pressure switch? HAVE you unplugged the unit from the wall outlet to reset the board? DO you have a voltmeter? If you do you can run voltage across the switch and if you get 24 volts you are open.

If you can get to the shaft of the motor, oil it using electric motor oil. If the motor spins freely, you just may need to replace the start capacitor, however if it is binding; you will need to replace the inducer as an assembly.

Bryant furnance clicking, won't fire


try checking the pressure sensing switch,it has a tube that should run somewhere close to the inducer fan.sometimes this hose fills with liquids,and makes the units act funny.I don't know if you have a condensing unit or what.the furnace wont try to light if it cant tell the inducer motor is running.any induced draft unit will work this way.you can also do a temp. bypass of the pressure switch to make sure the contacts on it are closing just be sure your inducer fan is running,and you cant leave it like that its just a test.that is a safety feature you really need.

Induced draft motor


The inducer motor is what takes the cabonmonoxide out of the house from the unit and should not be bypassed

Janitrol/Goodman GMP075-3 Draft Inducer Fan Won't come on


most forced draft fans are powered by 120 volts . close to the fan is usually a plug that unsnaps. create a call for heat after turning off to clear safetys and see if your getting 120 to fan on initial call for heat. if you are then fan draft motor is bad, usually sold as an entire assembly replace exact as it came out. sequence of operation is..... stat calls for heat via common and white wire to furnace , 24 volts. ......board sences call and sends 120 volts to forced draft ........ motor runs and creates pressure on proofing switch,....... switch closes 24 to board and tells it draft fan is on......... board then energizes ignitor,....... after ignitior glows gas valve is opened and burner lights ........ either ignitor or seperate sensor rod tells board the burner lit........ and a few minutes later the fan comes on and hot air is blown out. if a step is missed or doesn't proof the furnace either trys up to three times to light or locks out. turning off power usually resets safetys and it will resume attempts to lite normally.
