Question about Heating & Cooling
When you plug in heater the ignitor lights for about 20 seconds then shuts off do you have an explanation for this?
The igniter turns on and if there isn't any fuel flow, will shutdown and go into "lockout." check you have enough fuel in the tank. if YES then take your unit apart and replace the nozzle. there's a bronze filter in the nozzle. mounted on the back of the fan motor is an air generator. this air generator makes about 3.6 lbs of air pressure to pump up fuel to the nozzle from the tank. the nozzle acts like a venturi and creates a suction for the fuel.

1. Thermostat calls for heat. 2. Draft inducer motor starts. 3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes. 4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution:You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem. The furnace's control board might not be supplying the voltage to the ignitor.If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.
