i have been wrestling with this for 3 weeks now...intermittent heat in the house. i learned a lot in the last 3 weeks about furnaces.
it's a gas furnace, a york diamond 80, built in '95. house is 10 years old.
the issue is that the furnace kicks on, ignitor lights and then gas comes out and blue flames ignite to warm the place. for whatever damned reason the flames go out and the gas shuts off. it went from once a week to once every 5 hours. we not come home to a freezing house and wake up to a freezing house...and it's cold in chicago! when it just kicks off, the thermostat is still saying it is too cold obviously and to keep the furnace going....so, the blower still blows, now circulating cold air through the house.
to "fix" it i power down or "reboot" the furnace at the switch on the furnace. turning it back on makes everything good again....till the next time. you never know when it will go out next.
i replaced the digital thermostat with a $85 honeywell (sweet), i replaced the flame sensor and yes the filter is new. still an issue.
i called a heating guy out and he found nothing. he said it has to fail for him to fix it. understood but haven't you seen this before? when the furnace goes out the red light blinks 5 times, pointing to a rollout switch i believe.
i'm stuck. i was going to replace the circuit board on my own but that might not even be it.
thanks for reading.
