SOURCE: My heil furnace comes on and lights the pilot but

You need to remove the flame sensor on the far left hand of the burner. In has a single wire going to it in between the jets. I believe it is a white wire. A 1/4" screw holds it in place. It has a white ceramic base with a stainless steel looking probe that protrudes into the flame of the burners. Pull the wire off of it, then remove the flame sensor from the burner assembly.. Use steel wool to clean the metal probe until shiny. Re-install and enjoy your heat.

Yes, inspect the air intake, exhaust pipe, filter and condensate piping for blockage or moisture. Also check for a hole in the hose that goes from the small exhaust blower to the pressure switch or a bad connection on the switch or control board. You may be able to temporalily jump the switch for diagnostic purposes only.

SOURCE: Model GMPN furnace: burners light OK, but shut off

The unit is not sensing a flame. A flame sensor is a piece of metal rod about 1/8" in diameter which tells the unit it is burning. take it off and clean it with steel wool. if that doesn't work you'll need to replace it

On a conventional furnace of today, your furnace may have a flame sensor which is typically located in front of an end burner opposite the ignitor. It is connected by 1 wire. This metal rod needs to be removed by 1/4'' screw in most cases and cleaned. Clean with steel wool or even a clean greenie scrubber will work. Wipe clean and re install. Many problems can cause these symptoms, but this is a very common one.

You have a dirty or bad heat sensor. When you remove the front panel on you furnace you will see a probe that is 2 or 3 inches long that is in the flame when the furnace fires up. If it doesn't detect a certain temperature within the first 30 or 40 seconds it shuts down the furnace. You can either clean the probe off with sandpaper, or purchase a new one. They aren't very expensive and are easy to replace. In my experience it is usually a build up of carbon on the sensor and a good cleaning with sandpaper and alcohol usually takes care of the problem.

Hi,
It appears to be the fan limiter switch. It comes on at a certain temp when heating up and shuts off on the high end of its setting. Once the burners are shut down, the fan continues for a few minutes to cool down the burners. The limiter switch is adjustable but it sounds to me to be defective and should be replaced. Good luck and stay warm, :-)

Heil heater starts/stops before reaching temp


is installed in a vertical up flow or horizontal position , if in horz position you could have a bad or miss positioned roll out switch this is a thermal switch positioned toward the burner edge that if the flame rolls out of burner area trips and then resets as it cools allowing the furnace to re-start until it reaches temperature , something to check .

Furnace burner ignites then goes out


Sound like a thermocouple, or flame sensor.
If it has flame sensor make sure you check micro amps to verify operation, because it might be the board that controls the sensor.
