York Furnace (GY9S/GM9S/GF9S) Not working - 3 Red flashes on Diagnostic
Asked Nov 27, 2010, 08:30 AM
We have a york furnace up in the attic to heat the bedrooms. We had a major wind condition one day and the furnace stopped working after that. It has the three red-light diagnostic red blinks, which means either the -
Faulty pressure switch, broken pressure switch hose, blocked vent pipe or faulty inducer.
When the furnace receives a signal from the thermostat to provide heat, it starts for a minute, we can feel a slight air coming from the room vents and then it shuts off again.
We are novices and have no idea what to do... Can anyone guide us please..
Also.. the furnace is under warranty but parts are not, we do have extended home warranty also...
Who should I call... extended home warranty ? Furnace warranty? Or home-insurance? Or just call the repair man and foot the bill?
Thanks for the help..
