My furnace is short-cycling. I've tried the following:
- replaced the flame sensor
- Shorted the thermostat heat demand signal
- Checked the blower capacitor
- Checked the air intake filter
- Checked the exaust vent
It seems to only works after I cut the power to it for 8+ hours
When it starts working it will work for about 48 hours and then return short cycling.
It has only begun short cycling at night (maybe temperature related).
What else should I trouble shoot.
