I have a Amana Air Command 80 SSE gas furnace. The furnace exhaust blower will start then it will ignite, then the cold air blower will start up. The furnace appears to run well for a short time then it will shut down. If I wait and watch the error light during the start up process and immediatly after the first shut down the light is blinking 7 times (Low flame sensor) If I don't wait and come back later to check the error light it will be blinking one time, (lock out to many restarts) Can anyone tell me what to check? Thank you!
In the path of the flame on the last burner that starts, there will be a small rod. That rod is the flame sensor. Take a scrub pad and polish it. Also check the electrical connection that goes back to the circuit board. Disconnect any ground wire from the circuit board to furnace cabinet, sand it and replace it.
Amana Air Command 80 SSE gas furnace will not stay running
I cleaned flam sensor but still problem did not solve.
I had nest learning thermos installed 2 years ago. It lost connection to my phone because of low battery. Google said charge battery via usb socket for an hour. After that nest was back on line but heat was not working.
I replaced nest with my old thermostat and now heat is working.
control board has red light lit continuously and that means lost connection to thermostat.
Nest customer service can not accept that it was their fault.
