Sounds like the thermostat is set up to control the fan with a call for heat(usualy the way we set up a heat pump system) New thermostat?

My carrier model # 48ss-036100331 induced-draft motor will not start


On some of those inducer motors there is also a capacitor in the blower compartment on the left side of the burner section. It is possible that if you have 230v coming from the board CM terminals and if the motor is new maybe you have a bad capacitor in the blower section. Follow the wires to the capacitor and check microfarad reading to that capacitor. Caution there maybe 2 in this area but one is for the indoor blower motor and the other will be for the draft motor. The blower capacitor may be somewhere between 10 or 15 mfd but the draft inducer capacitor will be around 3 mfd. hope this helps

HEATER MAKING LOUD NOISES


Check the draft inducer motor for any partial blockages or dibri.

I've seen sticks, birds nest particles and pieces of deteriorating fan blades (squirrel cage type fans) cause this.

You might also find that the inducer motors bearing are going.

If its a loud vibrating grinding type noise, I'd suspect bearings or missing pieces of the blades. (unbalanced)
If it's a clanking type noise I'd suspect loose items hitting the fan.

The inducer motor will only operate right before and during burner operation, while the blower motor can operate at any time depending on your setting.

Goodman: My Power Venter (aka Heat and Draft Inducer) won't start


The power ventor most likely needs to be replaced. But be advised. Goodman normally will not sell parts to anyone but a certified technician. I had to show my masters certificate to buy parts from their outlet. This is a part that has a high rate of failure.

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.

Goodman 90% gas heater condensation build up


If the exhaust comes off the top of the furnace, you will need to make sure the condensation will drain all the way back to the condensate outlet found at the base of the inducer blower. If you are having to remove the tube from the pressure switch, there must be a blockage from the inducer down to where ever it drains to. Check to see if all tubes are free of blockages and if there is a condensate trap, clean it out. If the pressure tube you mentioned is facing up toward the blower allowing water to flow into it, reposition it so water will not enter the tube.
