SOURCE: GMPN 100-4 furnace. Blower motor runs when not calling for heat.

The board is bad. The unit thinks a flame is present, so it tells the blower to come on. Replace the board.

SOURCE: weatherking furnace is starting and stopping

This just sounds like a couple of problems. First, your blower is designed to only turn on once the heat exchanger heats up, so the flame will be on for a minute or two before the blower starts. it sounds like your blower is cooling down the heat exchanger too fast and causing it to shut off so it can warm up again...check blower speed for heat, it should be the lowest speed (black wire). Blue=medium speed, red= high speed. second problem could be your flame sensor rod is calcified, you just need to locate this and clean it off with some fine sand paper.it is located in the flames near the burners. Also change your filters, for proper air flow through your heat exchanger.

it may be clogged at the barbed fitting on the induced draft motor where the pressuer switch tubing connects. take a paper clip and **** it out make sure you can stick it thru freely till you can feel the Inducer wheel then reconnect and try again.

THE DRAFT BLOWER IS TURNING ON BUT NOT FIRING UP WORKING ALL DAY STOPPED OVERNITE


The induced draft motor has a induced draft proving switch that is a pressure switch , it resembles a silver round flat device about 4 inches across with 2 wires, it will have a tubing attached to it that also is attached to the induced draft assembly housing on a barbed port, this is how the induced draft is "proven" thus giving the A OK to go to the next sequence of operation which is ignition trial period, it will attempt a ignition sequence for about 30 seconds 3 times before it will lock out if it has a circuit board, if so a flashing code will be observed and the legend in the back side of the blower door will tell you the codes meaning.
What is wrong 80% of the time is the barbed port on the induced drafts assembly is obstructed by carbon and not allowing the pressure switch to "sense" / prove the induced draft motor is running. You can connect the pressure switches 2 wires after the induced draft begins, this simulates a operational pressure switch and should begin the ignition phase if all is well, otherwise if all safety's or high limits are closed, then the ignition module is bad.

This is for spark type, if you have a hot surface ignitor look to se if its broken or cracked or has a burned spot visible, if not try testing for 120 volts to it, if you read proper voltage, then the hot surface igniter is bad. 25360510-wil0gxehsfojcry3vcxysbjd-1-0.png

Hello, if the inducer motor is bad then the furnace will not continue further and work, it could be that the bearings are shot on the inducer or it has failed electricly. Best thing to do here is replace the inducer motor.

Hello, sounds like the limit switch is opening on the furnace.Usually when a furnace goes off on its high limit is becuase the airflow is being restricted making the furnace overheat. a limit switch is there to protect the furnaace from overheating, most cuases are either dirt or the blower motor not running up to speed, anything that cuts down on the airflow will cause the high limt switch to open.

The fan motor went out and the furnace is not even 5 years old.


I have an Amana High Efficiency furnace that I purchased 5 years ago this past October (2009). My furnace started making a horrible noise last night and then stopped working. The repair person, told me my draft inducer motor needed replaced, and showed me where the plastic fan blade inside of the inducer was "chewed up." Of course my first question is, "How can a 5 year old furnace need such a costly repair already?" The only answer I received is that it will cost me close to $500.00 to have the situation remedied (service call, parts, labor). I started looking around on the internet today, and discovered that high efficiency furnace inducer motors are usually encased in plastic and the motor fan blades are made of plastic rather than metal like the lower efficiency models. Turns out that these plastic blades over time can't withstand the high heat generated and in time (they estimate 3-4 years) break. The damage to the blades causes an imbalance in the way they spin, which in turn, generates the resulting problem of a damaged draft inducer motor. Appears this is a design flaw. Yeah! I'll say. I spent $3100.00 for a brand new furnace and 5 years later I'm paying another $500.00 and apparently can look forward to doing the same in 3-5 more years! Maybe this answers in part your question?

GMP075-3 intermittantly will run then shut off and not start


The led is flashing your fault code. You can look the code up by looking on the inside of your indoor blower panel. Please let me know what the trouble code is. I am guessing you will get a induced draft fault.

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.
