There can be several reasons your not igniting. You may have a dirty filter, safety switch engaged etc. There is a diagnostic light in the bottom compartment that flashes a code. see what code it is flashing and post that info. The breakdown for the code is on the back of your door.

    First make sure nothing is blocking your intake or exhaust vents both inside and outside of the home. Next, try removing the rubber tube that goes from the "vent motor" to the pressure switch(circular device with two wires going to it as well as the rubber tube) and sucking on it while leaving it connected to the pressure switch. By sucking on it you may free the diaphragm inside the pressure switch if it is sticking.

Hello, I have a Amana Air Command 80 model #GHI90A50, 22 years old. This furnace is on its third ingnition module (last one two yeras ago). The symptom I am trying to diagnose has been ongioing since this...


If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

Fan turns on, pilot on left side turns on red light at bottom stays solid during entire time then pilot goes out and blower stops no heat please help


On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remaing solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the igniter. The igniter will glow and you will be able to see it if viewed thru the small inspection port. Once the igniter gets hot enough, it sends a signal to the module opening up the gas valve (24 volts). Either a pilot will come on or the burner tube will ignite then spread the flame to all burners. Lastly a safety sensor will be looking for a certain temperature within a few seconds and the furnace will continue to operate and the room air blower will turn on in a minute or two.

What could go wrong? The unit will not run if there is no signal from the thermostat (bad thermostat or broken wire), the control module does not sense a signal from the thermostat (bad control), the inducer does not energize (bad motor), the pressure switch does not close (blocked vent piping, bad switch, plugged condensate hose), the igniter does not energize (bad control, bad igniter), the gas valve does not open or there is no gas (bad gas valve, broken wire, no gas), the pilot does not light (dirty pilot), the burner does not light (bad burner, plugged orifice, not enough combustion air), the flame does not spread to each burner (bad flame spreader, dirty flame spreader, more bad burners), the flame safety sensor does not detect flame (dirty or bad flame spreader, bad flame sensor, broken wire, bad control), or the room air blower does not energize (bad fan motor, bad control).

Gas ingnition does not start


unplug the dryer and check the ignitor,the sensor and the thermal fuse located on the blower wheel housing,also if the dryer works correctly for the first 15 to 30 minutes then will not ignite again you have bad gas coils,also if the ignitor glows but flame doesn't lite most likely it's the coils,while your in there vac out the dryer,the duct where the lint filter slides into and if the vent line is long blow it out with a leaf blower

Gas not getting to stove to ingnite


It sounds like you may be "vapor locking" the grill...after you are done cooking on the grill, how do you shut it off? Do you close the tank valve first then close the burner valves or do you turn off the burner valves then shut the gas off at the tank? If you turn the burners off before turning the gas off, you are creating a "vapor-lock" where air gets trapped in the line and you get the sputtering you are talking about.

Try this first, turn the gas on, then light the grill...once it is lit, turn off the gas and wait for the flame to fully extinguish then turn the burners off. Now try to light it again...if it is still sputtering, repeat the procedure above to purge the air out of the line.

If that procedure does not fix your issue after three tries, go get a new line and regulator and install then do that same procedure again. This should fix your issue once and for all.

If you experience any trouble with this, let me know here. Good Luck!

The igniter on the right front burner of my GE Gas cooktop does not work....I must use a lighter or match to ignite....What can I do? There is no clicking sound when I turn on the burner?


all burner igniters work at the same time - you may have a faulty electronic spark unit. change the spark unit. go to repair clinic dot come for the unit. also would be wise to check the ingniter start switch on the gas burner control knob

Question:
Did you replace the ignition switch or the KEY AND CYLINDER?

These are the only 2 things that can make your engine turn off when you release the ignition switch after starting the engine.

I hope this helps you.
