Question about Goodman GMS90703BXA Heater
My heater starts and fires up as normal in the past the blower would turn on about 15 seconds to 30 seconds.now the blower never turns on the unit shuts down and the digtial teromstatgoes blank.The blower works bacause it turns on with the centeral air.i replaced the blower about 2 months and the air worked great.im wondering if it is the termostat due to the fact that after the heaters fires up for a min it goes into a safe mode and shuts down but when you look at the theromstat up stairs it goes blank but when you move it to off and it cools down it starts to show the temp.
I have a Lennox Conservator III G16 and when I turn the termostat up to turn on the blower want come on, but on occassions my wife said that she tapped on the side of the furnance and the blower might start working. I vaccumed out both blower area and the upper furnance compartment, but still the blower want come on. Our dyer is located in the same room as the furnance, we had a HVAC associate check it out and he stated that we needed to vent our dyer outside to prevent dust buildup and a safety hazard. What do you think is wrong with our blower and we have not found a solution or method to vent our dyer outside as of yet.

Try to locate the red and white wires either behind your thermostat or on the furnace itself. Jump them out and see if the furnace stays on. If you do it at the furnace you will need to hold the door switch down. If it runs fine, you have found your problem (the thermostat) if it goes out again, the furnace will display a number of blinks on the circuit board. Look on the reverse side of the furnace access door and there should be an Error Code chart to get you started figuring where to look next.
