Hello, our Goodman furnace is malfunctioning. The blower motor runs non-stop. We are getting pretty cold now, it has been several days. I disconnected the thermostat and it made no difference. I suspect it may be a bad sensor, but do not know which one. The furnace is only 5 years old or so and we have gone through several ignitors already. I suspect that part was not too good of a design. Does anyone know which sensor I should start with? Any help would be greatly appreciated. Our six children are happier when they are warm. Thank you.

Is the circuit board blinking? If so how many blinks? Model of your unit?

Hello, thank you for your reply. The red light comes on for a couple of seconds then blinks three times. The model number is GMP 100-5 REV B.
