Question about Goodman Heating & Cooling
Goodman furnace model#GCH90904CXAB the red light blinks 4 times. The air stays on continuously but there is no heat. What could be the problem?
This model is equiped with a diagnostic error control. Take off the front panels and look for a wiring diagram pasted on the reverse side of the panels. On this diagram there will be a chart telling you what 4 blinks represent and where to start looking for the issue. I suspect the air filter may be dirty or the pressure switch may be bad, however make sure the condensate hoses are free of any debris. Good luck to you!
