Hi!!! If the flame turns on then off and on then you should change your flame sensor on the gas furnace..YEs flame sensor is shorted..The flame sensor is located by the valve burners it has one wire and is white..Good luck..

My goodman GMVC95 furnace circuit board is flashing On 6 I replaced the flame sensor but it's still flashing. Does it have to be manually reset?

Alright, have you checked the low voltage fuse on the circuit board in the blower compartment? Make sure you check the roll out switches as well. If all of these issue appear to be fine then you may have a bad circuit board. There has been a bad batch of circuit boards going around many of the popular furnace brands this winter. Trane Gas Furnaces and Goodman Gas Furnaces have been effected. We sell both brands and have had to replace many circuit boards on new furnaces.

Won't ignite

Be sure that that PVC vent pipe going outside is not plugged or trapped with water. If the vent pressure switch is not tripping the furnace will not ignite. Also be sure that you don't have a gas leak somewhere causing weak gas flow to furnace.

I have a goodman gmp100-4 gas furnace and the gas comes on but shuts off in around 30 seconds, then tries again and the same thing... can i get some help please?

On the last gas venturi tube there should be a flame sensor located in the flame to prove it exsists, if its coroded the spark can,t jump back thru the moisture molecues in the gas to prove it has a flame to tell the circuit board to keep the gas comming. Just reomve the flame snsor and sand itand replace itback. T. Y. V. M.!

Goodman GMNT 60 Furnace. Burners shut off after a minute and will not re-light. Board has one blink code says gas valve or flame sensor problem. Replaced flame sensor. Gas valve has a steady 24 volts and...

No, the board isnt out. The board has a code telling you that its out. Its your flame sensor. You wouldn't have gotten any heat if the gas valve was out. check if that flame sensor goes to another sensor on the same circuit , if it does check that. If it just a one wire sensor make sure its in the right position. If its a one rod flame senor with one wire I would sand it down with sandpaper. if its a two wire senor ohm it out to see if you ger current going through it.

Goodman GMNT furnace goes into 'lock-out'.

The brain has to have constant verification of flame. If the burner ground is corroded then you will get the condition you prescribe.

Adjusting goodman propane burners

Yellow flame can also mean inadequate gas pressure. Do you have a manometer? If not, call your gas company for a check.

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.
