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!

Rheem 90 Furnace ignites and cycles, blower motor does not turn on


So you turn up the thermostat, the burner ignites, the burner burns for 30seconds or so and then it shuts off. The blower never comes on. It sounds like a bad blower motor or the timer on the solid state control board is defective. On your thermostat do you have a switch that says fan on fan auto? If you do, turn it to fan on. Does the fan come on. If the fan comes on then I would be inclined to think that the blower motor is ok and the control board is defective.

I drained the heater tank I have a leak in the Tube Sheet Coil, but need to check the blower and igniter, if I put water back in the tank under pressure it will be forced back up the blower.


Ignitor already compromised. Blower is probably fine.

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.

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.

The burner never ignites


the clicker, sends a small electric spark (like a little lightning) at the tip of the burner. if it doesn't hit the tip, it wont ignite. check and adjust.

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.
