Question about Goodman GMS90703BXA Heater
Goodman furnace GUPI model, starts up fine but after the room warms up and flame goes out the blower runs for hours, what could be the proble? I put a new fan limit switch on but didn't solve anything.
Check the diagnostic indicator.
1. If the blower runs for hours make sure the fan switch on the thermostat is set on "auto".
2. The furnace safety system must be in lockout. This is the furaces way of telling you there is a problem.
3 Most common problem is a dirty flame sensor.
