The pressure switch, open or closed depends on the induce fan motor. the switch could of failed. Try blowing into it, in and out. And or your induce fan motor is not blowing out the excessive heat out of the furnace properly. We provide repairs in the So Cal Area.

Not sure what you have for furnace so I can only offer generic info. Take a jumper wire with alligator clips on each end. Hook one end of jumper to pressure switch terminal but keep original wires on it as well. You will have to slide the original wire back enough to clip on the jumper. Slide the second wire back as well but do not connect the jumper yet. Tape the door safety switch closed if you have to to be able to have the furnace run. As the inducer or exhaust fan spins up to speed, take the unused end of the jumper and hook to the second terminal of the pressure switch. This will fool the circuit board and the igniter should start to glow or spark. If this works, look for any blockage of the air intake pipe, the exhaust pipe, water or ice in any of the hoses, dirty air filter or restriction of the inducer fan. Even a small leaf can collect moisture and grow in size as it ices up restricting the vacuum. As the furnace runs, check the hoses going to the pressure switch to see how much vacuum is being produced by the inducer. This is what closes the switch. If you apply a small amount of vacuum to the pressure switch, you should be able to feel and hear the switch close. If not, replace the pressure switch.

Hope this is some help. Please rate my answer!

Open pressure switch is when your vent motor comes on it has to get a certain vacuum pressure or it won't ignite furnace. There should be some little black hoses connected to vent motor and maybe into heat exchanger, running to these pressure switches. Pull hose off one end and make sure hoses are not kinked or some times if hoses have sag in them they can fill with water. Other causes are if venting is obstructed or pressure switch is defective, especially if it got moisture in it.

Amana 90 furnace won't ignite. Inducer fan runs for 30 seconds then shuts off and nothing happens. Try to turn fan on at thermostat and nothing happens. Ac works fine.


Most likely one of two issues is occurring. Either the inducer fan is not providing enough draft because it is either spinning too slowly or the impeller is damaged, or the pressure switch that the inducer motor air flow is supposed to activate is not operating properly. If the pressure switch fails to activate, the furnace will not open the gas valve and fire the ignition believing that there is not sufficient draft the vent the combustion gases.

I need a part number for a pressure switch for an Amana Furnace GUCA070BX40


Check this out. You ave to apply negative pressure to make the reed switch click, that means you have to apply suction to the switch to check it. most of these switchs ain't the problem. Blocked tubing yes bad switch naw.

Furnace code light flashes 3 times /pressure switch stuck open


Check the intake and exhaust plumbing for any obstructions. I had same issue, turned out to be ice in the air intake plumbing on outside of house. This may be the problem. The pressure switch can be tested by pulling hose from purge motor that goes to switch and applying a small amount of suction. The switch should make a clicking sound.

Amana won't fire, inducer blower constantly runs.


It sounds to me like the pressure switches need replaced or they need removed and shaken upside down to get the condonsation out of them!Good luck and Thank you for using FixYa.

The led indicator blinks 3 times on an Amana 90 furnace. What does this mean? The furnace won't fire.


Pressure switch open. Remove the small hose at the blower assy and gently **** on it. You should hear the switch on the other end of that hose change states. If not then it's the hose (cheap) or the switch (100 bucks but tough to find 2 years ago) or the wiring to/from or the control module. If it does do you have a bunch of white **** (the gasket) coming out of the black blower mount? I had to remove broken gasket and Permatex the seal to create the proper pressure; that's probably your problem as well.
