Question about Goodman GMS90703BXA Heater

1 Answer

Goodman furnace model GMS90703BXA, won't start. When power is connected, a clicking at about 1 per second comes from one of the two components on the circuit board labeled ZETTLER AZ942H-1C-18DT(206). I can't tell which one is clicking, and it may be both. I used an automotive stethoscope to try to determine which one is clicking, but I can't tell. The signal LED is steady.

Check your flame proving system! Make sure that there is a spark and the sensing rod is cleaned free of carbon and soote!

Furnace comes on and ignites 2 seconds later in just shuts off.


you have a dirty flame sensor. turn the power off to the furnace. you will find a "single" wire under the burners connected to a porcelain base. unplug the wire. use a 1/4" nut driver. remove the screw holding in the sensor. gently pull out the sensor. clean the metal rod on the end with a fine grit sandpaper or fine steel wool. reinstall the sensor. turn the power back on. this should restore your heat

Furnace starts properly, then shuts down, led flashes 8 times


The first thing to look at is the flame sense rod.
