If your pressure switch is clogging then you need to check the flue pipe make sure it is not rusting. If it is the flue should be replaced and also think about replacing the pressure switch. Check your high limit switch also. If the pressure switch goes sometimes it pops the high limit

I have a goodman modle gms80703ana and at first the inducer fan would kick on in it's normal cycle then the furnace would shut off do to a pressure switch. Now the inducer fan only come on perodicaly...


First unplug your furnace to reset it then plug it back in with thermostat set to heat high enough to make the heat come on. As soon as the inducer motor came on you JUMP the 2 wires that go to pressure switch. Your igniter should come on and gas valve should open for heat. If the flame stay on the blower should come on after a few minutes. If it get to this point your problem could be pressure switch itself or inducer clogged.

I just put a pressure switch in it still dont come on i unplug one wire it will run and work


There might be a plug somewhere in your system. It could be in the venting or condensation hoses if you have a high efficient furnace.

Goodman GMP100-3 igniter will not ignite


Hello, verify if the igniter is receiving a 120 volts from the control board after the pressure switch closes. Sometimes a faulty control board can cause this problem if the igniter and pressure switch are good.

I am having issue with my Goodman airflowing heater system. I have changed the theromstat since my previous one seems to have messed up. Now I am having issues with my heater turning on and staying on even...


Hello, this could be a control board issue with the relay on the board sticking and in that case the board must be replaced, or the thermostat could be wired incorrectly.

When I turn on the T-stat to call for heat the inducer fan does not operate. Is it my pressure switch stuck closed?


If you unplug one of the wires going to the pressure switch, it will think it's open. Once the inducer comes on, plug it back in and it should read "closed". That should answer your question.

Goodman GMP075-3 Random Incomplete startup


If the draft motor starts then shuts right off and then a red light comes on usually means that there is a blockage somewhere. Check the pressure switch line, make sure that it is clear and the hole in the heater that the pressure switch vaccum line runs to is open. If that checks out then make sure that your flue vent cap is on and that it is not pressed down on the flue vent and that the gases can vent properly

Circuit board light blinks 3 times heater will not turn on


The error code refers to a defective combustion air switch. Coleman Evcons made around 2007 had defective pressure switches or as they call them "combustion air switch". Replace it and the problem is gone.

Goodman GMP075-3 ignition problem


OK, if the furnace is not lighting for even a few seconds, you have either a bad gas valve, bad wire, bad control module or no gas. The pressure switch is not the issue. Check all wires to the gas valve and look for 24 volts across them when the ignitor glows and you hear the click. Then test for 24 volts to ground. It could be a bad ground wire.
