Hiya! If your heater has a pilot, it may be out. If it has an electronic ignition, the issue could be one of a few things, including:

Low/no gas supply (Natural Gas or LP?)

Malfuntioning regulator - If you're having this issue often, it would pay to have the gas company come out and check your regulator to make sure it's not overpressurizing your house lines; the gas company usually owns the regulator, so the inspection and/or should be free

Malfunctioning electronic ignition - To check this, cut the power to your furnace and find a spot where you can get a clear point of view to the ignition tip. Turn on the heater and listen for the cycles as you watch; Fan, Blower, then you should hear the ignition start clicking as it lights the pilot. If you don't hear any clicking or don't see a small arc at the ignition tip at all, your ignition module is malfunctioning. If you do hear clicking/see arc, this probably isn't the culprit.

Good luck!

I replaced my fan control board because blower would not work but now heat is not coming on


Double check your wiring on the new board, you may need to jump your thermostat line to the "R" terminal on the ignition controller. There are two sides on the ignition controller. One is for line voltage (115-120) and the other is for low voltage (24). Be sure of these connections and it should be good to go.

Engine will not go to high speed fuel oil mist blows out .checked spark arrestor ,muffler,exaust ports.


If the mix is blowing out the muffler than it is flooded either due to improperly adjusted carb, stiff diaghrams in the carb or weak spark. Weak spark could be a bad plug, failing ignition module, or spark ouit of time ( sheared flywheel key).
Bad fuel will also cause this symptom.

The blower fan comes on several minutes before the


Bad fan switch. It may also be called a fan limit switch. If your furnace is less than 5 years old, the switch is part of the circuit board and you will need to replace the board.

Blower comes on and heater don't


Blower comes on then I am assuming no ignition attempt afterwards? If the blower ( Induced Draft Fan) is not being sensed by the safety pressure switch, ignition attempts are aborted until the fan is sensed. If there is a blockage in the vent system, ID blower or sense tubing itself, those would be the obvious starting points to check. If the pressure switch "makes" (closes) then your investigation should lead you to the ignition process. Is there a spark at the pilot burner (if there is one), Is the Hot Surface Ignitor glowing? Is the gas turned on? All can be checked visually.

BLOWER FAN WONT SHUT OFF WHEN THERMOSTATE IS OFF


The compressor coming on when the contact is pushed is o.k. they all do that. As for the blower fan not shutting off, some brands (Payne for example) the heating fan relay is a n.c. (normally closed ) relay. so if the time delay relay or thermal link are bad or not connected, the fan will blow even when it is turned off.
