Could the thermostat be too close to a supply vent??? The brainiac before me put the thermostat about 5' away from a vent in my house......the thermostat saw it was warm and shut the furnace off.....the rest of the house was frozen.... I moved it and no problems now.

Check the fan switch[ It may not be heating up enough to get rid of heat in the chamber, When chamber cools down, furnace will fire up again. Also check for blocked flu & or flu pipe clogged. Most furn. have a limit switch & again when it cools down ,. the furn. fires for a few minutes. If you need any more info. call Dave at 203-380-2331

well i took the furnace apart enough to get to the "A" coil. one side on the inside of the A shape was completely covered with fuzz/dust. scraped it off the best i could. very hard to reach.
also changed the filter.
we'll see ..............

winter sucks!

It's amazing what a $2 filter will fix!




Did that do it?

did the shop vac thing also.

dont think it fixed it

something else i noticed.
sat next to one of the registers and noticed after the burner shuts off the fan keeps running until cold air is coming out , then shuts off again. few seconds later it repeats the same cycle.
make any sense?
dammit

Take it off the wall so you can get to the wires behind it. you will need a small flat head .
