Hey all,
I have an an American Standard Freedom 80 two stage furnace with a honeywell thermostat. I have owned the house for 5 years. Last year the furnace started working intermittantly. This year it doesn't. This year when I turned the heat on, the thermostat clicks and it's green light comes on, and sends a call for heat which is indicated by the fast flashing red light on the inside computer in the furnace. The exhaust fan comes on, then the ignitor heats up bright white for about 10 to 15 seconds, but I get no flame. After the third time that the ignitor heats up, the exhaust fan shuts off, and the computer flashes a series of two flashes constantly. The front of the computer says that two flashes indicates "system lockout, check polarity".
So do you think I have a sticking valve?
Any help would be appreciated.
