Question about Goodman GMS90703BXA Heater
My 3 year old Amana is giving me some serious issues. I have had 5 servicemen over now who haven't been able to fix it. The problem seems to be that after a successful heating, the inducer blower does not turn off. The unit is then unable to fire again. At this point I get the double blink from the control module that translates to "Low fire pressure switch stuck closed" Any Ideas? Help!
Check the condensate drain, hoses and pump if it has one. Like Drumbanger says, check the pressure switch. Also check the intake and exhaust vent for blockage of water or debris. All water should drain back to the furnace and not collect in the venting. Your furnace has two pressure switches, replace the low pressure switch.

It sounds to me like the pressure switches need replaced or they need removed and shaken upside down to get the condonsation out of them!Good luck and Thank you for using FixYa.
