Draft Inducer Motor runs continuously and the furnace does not heat

If the Gas Furnace's Draft Inducer Motor runs continuously and the furnace is not heating, it is most likely "locked out" as a result of a safety device sensing a dangerous or out of ordinary condition. There are a few things you can check. Here is a video explaining how a gas furnace works and demonstrating how to identify some of the most common safety devices that you should check.

Furnace gas valve is not opening


YOUR FURNACE IS IN LOCKOUT MODE DUE TO A SAFETY FEATURE OF UNIT. USUALLY THE HIGH LIMIT HAS BEEN TRIPPED, OR YOU PRESSURE SWITCH FROM DRAFT INDUCER MOTOR FAULTY OR PLUGGED. IT WILL CONTINUE LOCKOUT MODE UNTIL THIS IS FIXED.

Gas was disrupted but now fixed. Can't get pilot light restarted? Obviously some other step needed as a result of gas disruption? Please advise?


Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad ignitor what I see most of the time is the following sequence of operation:


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. Please see "limits, rollout switches & furnace control boards" further down on this page. 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. Please see the pictures below to help you identify a flame sensor.

turns on but no heat


From what I saw when I googled you furnace it has a hot surface igniter. It only gets hot when it's time to light the furnace. You should be able to see it glowing red when the furnace is trying to light. The furnace has a safety feature which shuts the gas valve when it doesn't detect a flame to prevent gas build up in the furnace. There are other safety features also. If the draft inducer motor isn't running the gas valve won't open. Overheat switches some of which have to be reset manually. Adjust the thermostat until it calls for heat then observe what is or isn't happening in the furnace. It will go thru a purge cycle first. The draft inducer motor will run to do this. After the purge the hot surface igniter should get hot a glow, then the gas valve will open and the burner will light. Let me know what you find.

Janitrol/Goodman GMP075-3 Draft Inducer Fan Won't come on


most forced draft fans are powered by 120 volts . close to the fan is usually a plug that unsnaps. create a call for heat after turning off to clear safetys and see if your getting 120 to fan on initial call for heat. if you are then fan draft motor is bad, usually sold as an entire assembly replace exact as it came out. sequence of operation is..... stat calls for heat via common and white wire to furnace , 24 volts. ......board sences call and sends 120 volts to forced draft ........ motor runs and creates pressure on proofing switch,....... switch closes 24 to board and tells it draft fan is on......... board then energizes ignitor,....... after ignitior glows gas valve is opened and burner lights ........ either ignitor or seperate sensor rod tells board the burner lit........ and a few minutes later the fan comes on and hot air is blown out. if a step is missed or doesn't proof the furnace either trys up to three times to light or locks out. turning off power usually resets safetys and it will resume attempts to lite normally.
