SOURCE: flame sensor on a goodman heater

The flame sensor will be located either left or right of the burners and there will be only one wire leading to it. It is positioned so the flame hits it last. So if you watch your flame spread, it will be on the side last to see flame.

SOURCE: constant high pitched noise emitting from furnace

Hi,
This is probably a dry bearing in the vent motor. Those motors run at high RPM's and can make a deafening high pitched squeal if they become dry and need oiling.
Some of the motors have oil cups on them for dripping oil into and others;s are much more difficult as you need to guess where the bearing is and try to drip oil down into them or run the oil to them.
Any light weight small motor oil ike a sewr machine oil will work.
Many hardwares have small oil bottles with extending spouts made just for oiling motors for just a couple of bucks...

The other thing that can cause this is if the blower wheel is coming loose and has moved to the side and is hitting the side of the blower housing. Take the bottom cover off and check for play or movement side to side in the blower wheel. Spinning it with the power off by hand may give you a clue as you will hear it scraping the side of the housing.

Depending on the age of the furnace you may be able to adjust the cool down. On some furnaces there is a silver box usually made by honeywell. This is your fan limit control. If you take the cover off you will see a dial with different temperature settings with 3 pins in a grove. The first one is fan on with temperature rise this turns the blower on when the furnace starts and warms up. The second is the fan off after furnace shuts down, this would be the one you want to adjust to a higher temperature to keep the blower from blowing cold air. The last pin is the high limit if the furnace gets to this temperature it will shut the furnace off but keep the blower running. Make sure that the thermostat fan option is set to auto and not on.

Good one! Is the flame getting to the flame sensor within the few seconds? Maybe a good cleaning of the burners or flame tray would help. 1.3 ma is enough for the flame rod to tell the board to stay on. Re-do all the ground connections both at the board and furnace cabinet to be safe. Check the polarity of the power going to the furnace. What are the chances the second board is bad?

Goodman furnace gmh95090cxac wont stay lit keeps clicking will lite then clicks back off what would be the problem


Hello, if the burners light but do not stay on for more than 10 seconds, I would clean the flame sensor. The flame sensor is a metal rod that is on the opposite side of the Igniter, sometimes it gets coated by oxidation and does not sense the burner flame and shuts the Furnace down. To clean to kill power to tje furnace, remove flame sensor and clean with a steel wool, then reinstall and start Furnce back up. If this does not work then most likely the Igniter is too weak to ignite the gas and will have ro be replaced.

Goodman furnuce cycling on lights, burner runs 6-12 sec, kicks out exuast fan runs, cycles through and does the same thing after 2-3 minutes, could this be the thermelacouple?


If your furnace has an ehxaust fan, your furnace does not have a thermocouple, it has a flame sensor. The flame sensor is a small metal rod that is in the burner area. It has one wire leading to it. Your problem seems to be flame sensor. If unit does not sense flame, it will kick off the gas valve.
Turn power off, take sensor out, (should be on 1/4" hex screw).. Probably some white film on sensor. Clean with steel wool, or dollar bill if don't have steel wool. Replace sensor.

GOODMAN GAS FURNACE. IGNITOR GLOWS, GAS FIRES FOR 3-4 SECONDS THEN SHUTS OFF..CYCLES OVER AND OVER. SOMETIMES IT STAYS ON...THEN SHUTS OFF BEFORE TEMPERATURE GETS UP TO THE STAT SETTING...


I suspect that the flame is not traveling to all the burners within a given time so the flame sensor is shuting down the gas valve. Clean out the flame rail where the flame travels and carefully brush off the flame rod with an old tooth brush.
