I have 15 year old Amana horisontal furnace model gsc075a30a. it was working fine till the exhaust fan cracked and needed replacing. I have done that and the fan works good but I had to bypass the pressure switch witch is not engaging. can't seem to find a replacement switch. Any suggestions?? Regards Jack

    We have the same furnace. Just recently replaced the inducer motor blower. There was water also found in the pressure switch tube that would stop the furnace. We had someone come out and put the pressure switch higher and it was working fine, until today. You can hear the blower motor running, but nothing is moving and furnace wont click on. Any suggestions, does this have to do with the pressure switch too?

If there are markings on the pressure switch as to what pressure it closes at, you may be able to substitute another brand pressure switch. Amana is made by Goodman. Maybe you can cross reference the switch with a Goodman distributor. Try Amana parts at 1-407-699-5411.

Furnace blowing warm air, ac overheats


Sounds like it is tripping on it's high pressure switch. This could be caused by a dirty condenser coil, overcharge of refrigerant, or non condensables in the system ( air most likely). I would get a second opinion from a repuatable company, sounds like he's trying to rip you off.

Bryant-Carrier Furnace Fan Stays On


I suspect a bad fan relay or bad fan control. Maybe the longer the control or relay is in the on position the more chance of it sticking on.

Amana Air Command 90 - Model GSC075A30A


water should never reach the nipple for the pressure switch tubing on the IDM. Check the entire condensate drain system for obstructions. Verify water makes it from the furnace location to the outside drain. Flush p-traps and any anti-siphon devices thoroughly.

150000 1974 national gas forced air furnance does the fan come on the same time the gas comes on. ...


not familiar with that particular model but on virtually every type and style of furnace i have worked on in the last 21 years. the fan is delayed. usually the burner lights then 3 to 5 minutes later after the heat exchanger has gotten nice and hot the fan comes on and blows nice and hot air. on old furnaces there was and is a switch usually on the upper right side of the furnace bulkhead that has a spring like device that heats up and rotates till it makes a set of contacts that turn the fan on. if it gets to hot the set of contacts breaks the power to the gas valve and shuts down the burner. as the furnace cools down on shut off there is a third set of contacts that open to turn off the fan so you don't get a draft. sometimes the stat can be wired up wrong, and it will bring the fan on right away ,and air will be cool and drafty till furnace catches up.

Amana furnace


This is no doubt due to failure of the "hot surface ignitor". This device lights the main burners for your furnace, and they fail a lot. I strongly recommend the replacement should be done by a technician.

Amana Air Command 80, 20 years old. Electronic ignition. Furnace does not start. Good power to furnace. Themostat properly set. Where do I start looking? Bob


Hello Bob,
Welcome to fixya,

You said, Amana Air Command 80, 20 years old.
Electronic ignition.
Furnace does not start.
Good power to furnace.
Thermostat properly set.
Where do I start looking?

Sounds like you possibly have one or more bad jets if the unit is a gas furnace!
Let me know how it goes.
Huuum

WOW, listen to this story!
I understand you are looking for the solution to fix your furnace your self.
But I want to tell you my story about my smart wife and our furnace.
When we moved into this house the furnace was 20 years old and she suggested that we put a new one that it will save us money.
I laughed at her and replied if it's not broken why fix it!
Six years later it finally broke down and I replaced the whole furnace and central air unit with a new one.
Our utility bill went down $100 dollars a month!
That's $7200. that I lost over 6 years due to not respecting my wife's power of reasoning!
If you can afford it or can get financing replace any unit 20 years old and it will pay for it self.
Can you imaging $1200. a year for 20 years is $24,000 dollars I'm saving with a new and efficient unit.
Do the math!!!!!!!!!

Thank You,
Huuum, Hope I gave you some good fatherly advice.

Carrier Weathermaker gas 8000 will not ignite


Your hot surface igniter may be bad. It may be cracked which would prevent it from starting the burner flame.
