I have a
Goodman GMH81155CN Gas Furnace
115,000 BTU Furnace, 80% Efficiency, 2-Stage Burner, 2,000 CFM Multi-Speed Blower, Upflow/Horizontal Flow Application
as of last night these have been the symptoms:
3 click - RED LED at the bottom motor circuit board comes on
4 click - RED LED is still on
5 click - sounds like a double click and exhaust motor comes on the RED LED is still on, but after 2 - 3 seconds the exhaust motor cuts off, RED LED turns off, and the cycle repeats after about 2-3 seconds.
The HSI doesn't glow at all.
I switched off the heating functionality at the thermostat control, then went back to the unit to pull these fault codes:
3 - pressure switch stuck open
4 - open high limit
I used this site to check the high limit switch
