The problem is not constant. Sometimes it works, and sometimes not.

    Mod. GMH950703BXAA...Furnace ignites normally and runs for one minute, then the flame blows out. The ignitor comes on and it relights and runs for another minute or ninety seconds and blows out again. This continues until the set temp is reached. I replaced the thermostat and cleaned the flame sensor but problem still persists.

Sounds like a thermocouple, or flame sensor.

It sounds like the flame sensor is bad. If thats not the case you may need to replace the control board. You should make sure the flame sensor is directly into the flame.

Rheem corsair. Just replaced control board and now igniter come on , burner lights but doesn't stay lit. Took out flame sensor and sanded and replaced. Still same issue . Is the sensor bad or can i


If the sensor does not I.D. a pilot, the furnace would not fire, so your OK to this point. The sensor needs to stay in a flame constantly once the main burners light. Sometimes the draft will cause the flame to waver and cause a shutdown. Also, if the blower fan does not start on time, the furnace will shut down. I would check for wavering first.

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 dependable 92,7years old. Furnace works sometimes. Checked out by qualified technican. no problem found. Constant checks shows troubleshooting light blinks three (3) times. Help please. 3...


This indicates a open limit switch on the furnace, the heat exchanger is getting to hot therefore the limit switch is opening and not allowing the furnace to work properly. Did the techinician check the limit switch on the unit?

Heating problem


It sounds like your flame sensor is bad. It is on the opposite side of your burners from the ignitor. Sometimes you can take steel wool and rub it on the sensor (which looks like a single rod) to clean it for a tempory fix.

Furnace pilot problem


check the pilot gas pressure, might be too weak and blowing out when the blower starts, the clicking noise is the gas valve shutting down when it detecks no pilot flame, that park is normal.

Unable To Keep Pilot Light Lit!


I have a Williams top vent gravity wall furnace (model 5009622) and I had the same problem. I had to take the cover off the furnace -- screw on top and two at the bottom (open the access door and there is one screw on each side) to get to the reset button for the vent safety shutoff system. On my furnace it's on the left side toward the top of the unit. I pressed the little red reset button and it's been working ever since. If your furnace is properly installed and doesn't have bird's nest in the chimney, it should work fine. Good luck!
