Amana 80 SSE Air Command Gas Furnace :: No spark, no flame, no heat…fan only
Fan turns on briefly, no spark or flame, then shuts off in a few seconds. Already pulled out the igniter and gave it a light brushing with an emery cloth (didn’t touch it with our fingers) Getting 8 quick flashes of the LED in the service window. According to the manual, that means one of 4 things: -Pressure switch hose blocked, pinched, or misconnected. -Blocked flue and/or inlet air pipe, blocked drain system, or weak induced draft blower. -Incorrect pressure switch set point or malfunctioning switch contacts. -Loose or misconnected wiring.
