It most likely is not stuck..... It is just doing its job. You "most likely" have over problems. To "properly" diagnos this problem you will need a manehelic gauge. You can have a wide variety of problems from as simple as a blocked or disconnected vacum hose to a lifetheatening problem.... a blocked flue pipe or a bad heatexchanger.
BE CAREFULL
GOOD LUCK!

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.

My Goodman furnace, model GMS80903BNA, is not working. I removed the back panels and checked the pressure switch. That seems to be working fine. The exhaust inducer spins up, the igniter starts to glow,...


That blinking 3 times is indicating a pressure switch problem. Try checking for water or a blockage in any of the hoses going to the pressure switch or condensate drain. Check the air intake and exhaust pipe for any blockage including any saggs that may hold water. Make sure condensate drain or pump is working. If you get a glow from the igniter, there may be a blockage in the gas valve or piping.

Hello. I have a Goodman furnace model no. GDS80453AMA. The furnace indicator light is blinking 3 times, which according to the schematic, is "pressure switch stuck open". Previously I've had the furnace...


The pressure switch requires a negative pressure (vacuum) to close the contacts. It is measuring the pressure in the inducer and indirectly ensure there is good combustion airflow throught the heat exchanger. Check for a small vacuum, in the neighborhood of 1" water column. Usually the vacuum required to close the switch is stamped on the vacuum switch. Check the vent pipe for obstructions and correct size and installation.
If the pressure aka vacuum switch does not close the furnace will not continue with ignition, for safety reasons.

Goodman Furnace GKS9 pressure switch problem


Disconnect the small hose that goes from the pressure switch to the inducer motor housing, at the housing, and stick a paper clip in the tiny hole, and pull it up and down, and twist it. this small hole is probably dirty. good luck.

Need to find the pressure switch on my goodman furnace


It's mounted onto the gas valve. It will be a button or lever that you have to push in or down, depending on the style.
