My central boil (fire+blower) comes on per the temp set by the thermostat; however, after the desired temp is reached --the blower go off but the fire (or flame) doesn't. Causing it to start burning-up the electrics (and God knows what else!) Can someone aid me with this? What could be cause this?
Answers:    CONTROL PROBLEMS.Sounds like a section with a control board.A follower limit will not shut bad the blower if the burners are still on. You will need a pro-sorry.
Call the Heat and A/C company to go and get it fixed.
