If you get a flame for about 2-3 seconds, than is goes right out, it would be a flame sensor, get some fine sand paper and clean it reinstall and should work fine, the flame sensor would be on the left hand side normally on goodman , looks like a stright rod with only 1 wire going to it, normally a white wire.

If the burners come on for a few seconds and shut off check the flame sensor near the burners and clean it with steel wool, usually this will fix the problem. The flame sensor is a metal rod that is immersed in the burner flame on the opposite side of the igniter. robhvac47_7.jpg

Set thermostat to auto switch unit to heat. Unit lights runs for a minute then shuts off. Fault light blinks4 times, msg. Open high limit.


Check air filter for blockage, clean off flame rod found in the flame pattern of the last burner that ignites, check high limit switch with multimeter to see if good (found above the burner box). Make sure room air blower turns on within 90 seconds of first flame.

Not staying lit


Remove the front panel and tape down the door safety switch so the unit can turn on when door is off. Turn up thermostat to make sure there is a call for heat. The circuit board should indicate a call for heat with either a blinking light or a solid light. Then the exhaust fan should turn on clearing the venting from any fumes. When the fan has ran for a few seconds, the igniter should start glowing orange. After it reaches a predetermined temperature, the gas valve should open with a click. The flame will start at the burner closest to the igniter and travel away from the igniter. There is a small flame rod located in the flame path on the last burner that tells the circuit board it feels the flame. If the flame goes off within a few seconds of starting, you have a dirty flame rod. Clean it with a scotch-brite pad. Once you get the flame to stay on for 90 seconds or so, the room air blower will turn on. If it tries 2 or 3 times to start but does not, the circuit board will record a code and display it with a blinking light. Look on the door panel for a wiring diagram. There will also be a Diagnostic chart that will tell you what the pattern of blinking lights represent.

Good Luck!

I would guess that the fan off setting on your limit is set a little to high. If you have the manual you can see what it says about changing the running time for the fan after the burner has shut off look on the control board and you should see two switches,one to set the time for burners to fire before main blower starts and one to set time for fan to run after burners shut off. To help with the problem you are describing set fan run time up so fan wii run longer. Hope this helps. Thaks.

Burner ignites and goes out (Goodman Gas-fired furnace)


Hi,
The problem you have is water in the exhaust pipe.
Check to see if the pipe has sagged anywhere or if there is a trap in the line.
If you hear gurgling then it is definetly water....
Some times can be hard to find, even a pipe 1/4 full will cause problems. They are very sensitive to flue problems.
Make sure that the flue pipe either runs back to the furnace or out to the outside, a continuos slope either way witha high spot in the middle.
Also check the bottom drain of the blower if it has one, have had them plug and trap water also..

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

No Heat Goodman GDS80904BNA


If the hot surface ignitor comes on and fires the burners, and then shuts back down, you need to take a look at the flame sensor. It is a ceramic rod with a metal tip that rests in the pilot flame. When heated from burners, it sends a signal to the main control module, circuit board, which ever this unit is equipped with to keep the burners on. It is a safety to shut the burners down if there is a problem. Take some fine steel wool to clean the metal tip on this and this should take care of the problem. If this does not do it, then 99% of the time you have a faulty control board or module. It will have to be replaced.It is where this flame sensor connects.It will continue to drop out of the circuit, and the fan will start and run. You're T-stat is good or the Hot Surface ignitor would not glow. You will need to take as much info you can from the unit, Goodman and the control, all numbers with you.You can purchase this part at a appliance parts house, or air conditioning parts house. Please keep me informed, I would like to hear back from you. I hope this has given you some direction to follow.Good Luck,

The exhaust blower starts for about 15 seconds then shuts off. several minutes later, the same thing happens - over and over


goodman furnance the exhaust fan starts, igniter glows hot, all burners lite up & will burn for about a minute and shuts down . I think it senses the room blower does not start so it shuts down.

REPLACE BLOWER MOTOR

if its spinning free until motor is energized motor may have bad armature or brushes.

If you energize blower and manually give fan motor a spin will it start if so replace cap.

No heat, trouble shooting light has continious flash.


There is a vacuum sensor on most units tied from the exhaust gas fan to the sensor. Does the unit try to start? If the unit's exhaust fails to pull the switch it will turn off after about 30-45 sec after starting. "IT" thinks it's not exhausting and stops to keep from overheating. Do you have this exhaust fan and rubber hose to sensor? Can you see if that fan is turning on start?

Duct fan comes in, igniter lights, but no flame


Remove the front panel. Tape the door switch to the closed position. If the thermostat is calling for heat the furnace should do the following: a light on the circuit board will flash and then the exhaust blower will start. A few seconds later (10-15) you should hear clicking at at the circuit board and an orange glow should be seen thru the small viewing port. A few seconds later the gas valve should open and the orange light will turn blue. If the blue flame only lasts a few seconds and then goes out, their may either be a blockage not allowing the flame to travel to all the burners and not allowing a flame sensor to sence flame, shutting down the unit. After a few cycles of not starting, the circuit board will flash a series of codes that you can read if you look on the back of the front cover. It will give you a starting point where we can research and come up witha more difinitive answer. Let us know what you find for codes.
