Question about Goodman Heating & Cooling

1 Answer

Hello there, I have a Goodman GMH951155DXAC furnace that I got in 2007. I have the following problem for the last 4 years: When the thermostat calls for heat the induced draft motor comes on and 30-40 seconds later the igniter heats up (glow) for few seconds, however some time the pressure switch will not close ( I do no hear the click during closing). After the second attempt the furnace will go into lockout and it will start to blow cold air into the house. Often after resetting of the system the furnace will turn on properly, however some time I will have to do it few times. When the induced draft motor starts I can hear water inside the draft inducer, however the drainage tubing from the induced is not clogged. I do not know if it is normal there to be some water? If not, this would mean that there is something not allowing all of the water to drain. Thanks

With furnace OFF ,Disconnect the top of the hose that leads to the
Bottom of Daft inducer Box, Now blow into it water will come out
of the drain hoses "condensation " this will shut the unit down if not drained. There must be a Trap on the side of the Furnace with water in it , to have positive presure to suck out condensation. This will fix problem. some installers forget to install this Trap that comes with Unit.....!!!! A little item
that will shut the whole system DOWN. :o)

SOURCE: Induced draft motor

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

SOURCE: Furnace blows cold air, ignitor won't glow.

ok this is going to sound funny but it seems as though the polarity is reversed going into your furnance. to correct this proiblem you first need to unplug the unit and where the cord goes into the furnance at that connection disconnect the two wires. Once theses are disconnected switch the wires .All you are doing is reversing the way the electricity flows into the circut board. I would wager that is the problem

SOURCE: goodman furnace draft inducer motor doesnt start


Using a voltage meter check and see if you have 120 volts at the motor... if so then the motor is bad....

If there is no voltage to the motor then the board is bad....

Replace the motor or board as needed...

My gas pack won't light

First, the thermostat white wire is the wire that initiates the furnace to start. When you select heat on your thermostat the tech should get a 24-28 volts between the white wire and common on the thermostat wire in the furnace. If you do not get the required voltage, there is a break in the wire from the furnace to the thermostat that needs to be tracked down and eliminated.

I am working on a Goodman Furnace an I cannot get power to bring on the induction fan. I have a solid red indicator light.

Hello, if you have power to the furnace but no power to the inducer motor terminals, most likey the control board is malfunctioning. However make sure that you have 24 volts at the w and c terminals on the control board to verify that you have a call for heat from the thermostat.

Hello I have a GMP 150 installed last year. The furnace works fine, but after a day or so, it does not react to the thermostat. so the led light of the thermostat is solid red, but the GMP 150 does not...

This sounds Programmable Thernostat related. Do you have a new thermostat? And are you familiar with how to overide the progammed feature, such as set on manual or push the hold button. Thermostats are generic so you could have any make or model. If you feel confident you could install a different Thermostat. You just need to unplug and then mark the wires accordingly- there should be 4 wires. There are a couple other things that could be happening is your unit may not be lighting properly. If you go to the unit when its not working I believe your unit has a blinking light on the circuit board of the unit that will tell you what problem is occuring. The code is affixed to the furnace panel I believe. There are so many safetys on your unit, the best way to troubleshoot is that tattletale light. Good Luck

Electric furnace runs but won't shut off on heat setting

I would insist that Sears either have a Senior tech come out and fix it or return it to the state it was prior to them touching. Then call some one else. Have them involve the Goodman rep in your area.

Heating not working

There could be a number of other potential causes.
1-Ignitor failure
2-vent blockage
3-tripped rollout safety switch
4- tripped limit control
Look at the door of the unit for a explaination of the number of flashes of the light. This may get you started in the right direction.
