HVAC folks? Furnace won't kick in - thermostat clicks?
Yo Creekers. We got any HVAC people here who might have an idea what is going on with my furnace?
- We have a forced-air natural gas furnace - mid efficiency, probably 20yrs old
- have a Honeywell Chronotherm III thermostat
- tonite the furnace won't kick in. The thermostat seems to keep trying - instead of a single click, when the heating cycle starts, it gives a double-click and nothing happens.
- I can manually turn the fan on.
- I have been down and pulled the cover off the furnance and it is just sitting there - the pilot light is not kicking in.
- I think we changed the batteries recently, but I'm not 100% sure. (and as soon as my wife gets home from her errands I'll pop out for a new set just to be sure.)
Turning power off resets it
Many of the flame safety modules have to be reset after a flame-out. One method of this is to remove power or the demand for heat. This can be accomplished by turning off the breaker and usually also by turning off at the thermostat. A sudden gust of wind that blows down the chimney/stack that puts out the pilot can set up a flame failure event. Hopefully that is your only problem. :)
