Amana Furnace Assistance
Good Morning. First time on the forums - I've searched through the archive but can't find the solution to my problem and with it being about -30C outside, I don't want to delay!
Bought my first house in September and am now having trouble with the furnace. It is a Amana Hi Efficiency 80 Natural Gas Furnace, Model Gu1070C30B (some 0s may be O and the 1 an I) with a 50E47-170 controller.
I found the house was cold yesterday after returning from work and I noticed that the controller (I apologize if some of my terminology is off) was blinking red and there was no flame but the fan was blowing.
I adjusted the thermostat higher and after some time, the furnace was operating normally. But then, later that night, the same problem occurred with a blinking red light, no heat, but later 'resetting' and producing heat. It seems as though the furnace will occasionally light, but not every time. When it does not light, it appears to go through its full processing including the electric igniter glowing, but fails to produce a flame.
The controller will flash red, but I haven't been able to count the number of flashes as I haven't been there when it started and it doesn't continue to flash after a pause. I also dont have the original instructions to identify a code; but there appears to be at least 8 flashes, but I could be mistaken.
Potentially coincidentally, I have also found lately the natural gas stove will fail to light, sometimes requiring a BBQ lighter to start. May this just be two failures at once, or connected issues?
Both appliances are in good shape and appear well maintained by the previous owner.
Any help or suggestions would be appreciated!
