Question about Goodman GMS90703BXA Heater
I have a goodman gsm9 furnace and i wanted to know what the default setting was on the integrated control module. Is the light supposed to stay continuously on? I've found some places saying yes, but the manual says that if the furnace is not working and the light is continuously on, the furnace may not be getting a signal from the thermostat. I'm pretty sure the furnace is working because if you turn the temperature up, you can here the furnace start, see the burners ignite, and the temperature of the room on the thermostat increases.
The light is supposed to be on, if there is a fault in the furnace the light will begin to give u a flash pattern... ie; three flashes...or two flashes.. on the furnace exterior or on one of the doors there should be a fault code chart.... read the chart on the unit it will tell you what light is on and when..
