furnace question???

furnace question???

furnace question???

(OP)
I set my furnace to 65.  It blows out hot air and works just fine.  But once it gets to 65, it just keeps turning on the exhaust for the furnace.  I have a natural gas furnace.  It will click on for 5 seconds, then off, wait 5 seconds back on, then off.  It will keep on doing this.  Anybody know what is causing this????

RE: furnace question???

you need to call a repair technician

this forum is for engineering inquiries

RE: furnace question???

Could be the diferential on the stat is set too close or the heat anticipator is is set wrong.
