Hello, sounds like the limit switch is opening on the furnace.Usually when a furnace goes off on its high limit is becuase the airflow is being restricted making the furnace overheat. a limit switch is there to protect the furnaace from overheating, most cuases are either dirt or the blower motor not running up to speed, anything that cuts down on the airflow will cause the high limt switch to open.

Turns on but no heat


From what I saw when I googled you furnace it has a hot surface igniter. It only gets hot when it's time to light the furnace. You should be able to see it glowing red when the furnace is trying to light. The furnace has a safety feature which shuts the gas valve when it doesn't detect a flame to prevent gas build up in the furnace. There are other safety features also. If the draft inducer motor isn't running the gas valve won't open. Overheat switches some of which have to be reset manually. Adjust the thermostat until it calls for heat then observe what is or isn't happening in the furnace. It will go thru a purge cycle first. The draft inducer motor will run to do this. After the purge the hot surface igniter should get hot a glow, then the gas valve will open and the burner will light. Let me know what you find.

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.

Trying to determine whether I have a bad Ign/Lockout or inducer relay board on Mod 58SXA080-GG. If I shut off heat at t-stat or unplug ign mod. for 10 min. It will usually intiate a heat cycle but I only...


The inducer blower will put a vacuum on your pressure switch which in turn will tell the board to apply power to the ignitor. If you have a vent blockage, dirty air filter, plugged condensate line or any blockage of either vent or air intake, the furnace will lock-out and flash an error code on the circuit board. If after inspecting all the above for debris and found nothing, you can quickly jump the pressure switch after the inducer starts to see if the ignitor glows. You could also have a bad ignitor. Yes the lock-out is normal. Looks like you discovered the cause on your own, order a new switch.

Three blinks on gas furnace, will not maintain flame


3 blinks indicates a pressure switch error. Check or replace air filter, condensate hoses for blockage, check small hose uo to pressure switch(s), check the vent pipes to make sure they pitch back to the furnace, check the air intake and exhaust pipes for any blockage outside. If all looks good, jump out pressure switch as soon as the exhaust fan starts to turn and see if unit starts. If it does, replace pressure switch.

Goodman code problem three blinks


Same problem with 1 yr old Goodman. Checked entire exhaust and pressure switch. Inside fan, pressure switch hose clogged with crusty white gunk. Cleaned it & furnace fixed. I have no furnace repair experience, but love to "play MacGyver". Hopefully this could save someone a service call.
