Amana furnace won't stop running, won't heat and alternate heat pump won't turn on.
Jump out limit switch blower should stop and inducer should come on then the heating sequences should start from there
SOURCE: Furnace Went Out! HELP PLEASE!!!!
The door closed or open should have no effect. The draft motor runs, no power to the glow plug or it is open,
The first place to look is at the furnace brain, a box located somewhere in the unit connecting to the gas valve, look at this brain [controller] and there should be a light of series of lights.
On the box itself there should be a matrix of codes such as: green light flashing= bad glow plug, or red, bad controller box, do you have anything like this?
Most have some sort of led light that narrows down the problem.
If not at least do these things:
make sure the power is off, and that the blower motor spins by hand freely.
next if you have a volt ohm meter, you can test the plug to see if there is a circuit, if the glow plug is open, that is one problem,
If you have a volt meter you can measure the leads at the plug to see if voltage is there or not.
There are so many checks and switches that will operate dependent on the operation of something else.
Unplug the furnace and keep the power off the brain, if so equipped for several minutes, see if it resets.
If it does great, if not tell me if there is a brain box and what the lights are, and what the matrix of light codes say, and we can go from there.
You can also measure for voltage from the thermostat to the furnace and make sure it is getting a signal on all wires, a thermostat wire could have come loose.
very difficult to troubleshoot a furnace when one is in front of it, let along without seeing it.
If you find no box, let me know, and let me know from these checks above if anything changes, or gives you more info to pass on to me.
Step at a time we can find this, a volt ohm meter will be really helpful.

Hi!!! Does your ac unit work fine?If not check your low voltage problem..You have a low voltage problem check the wire going out to your condensor make sure that they are not touching..Good luck..Check low voltage wires..short in progress..

That blinking light may be the diagnostic light. Count the blinks next time it fails. Carrier units will have two different blinks depicting the error code such as one blink followed by a pause than 3 blinks giving you an error code of 13. Then look at the wiring diagram, it will have an error code chart telling you where to start with your diagnosis. You already know that if you remove the cover it erases the error code, so look thru the small window first.
