Gas Furnace Burners Won T Stay Lit

Why won t my gas burners stay lit.

Gas furnace burners won t stay lit.

It s always good to give your grill a thorough cleaning burners included. Then they go out and the process repeats. This is accomplished by a flame sensor. It is a piece of pipe situated in the flame of the burner.

There is nothing worse than putting food on the grill to come back and find it cold five minutes later. Another issue could be the burners are dirty. After a gas furnace opens the gas valve to allow gas into the combustion chamber the furnace control board will monitor for proper ignition of the gas. The things i ve tried besides reading lots of.

The furnace stays on for a short time 1 to 10 minutes and then goes out. This is the most common furnace problem which also happens to be the easiest thing to fix. The gas valve sends gas to the main burner s which is lit by the pilot light. When the flame is turned on this piece of pipe which is filled with gas heats up and expands.

This continues until i turn the thermostat off. If you have a direct ignition furnace you won t have a pilot light. Are your furnace burners only coming on for a few seconds. Gas furnace burners won t stay lit.

The burner ignites but goes out before your home is heated when the thermostat is turned up the furnace ignites and the burner comes on. The flames and pilot light go out but the fan continues to run. I ve got an older natural gas furnace lennox model g16q3x 50 1 which refuses to stay lit. These furnaces skip steps 3 5 and instead light the burner directly.

If the flame sensor does not detect a flame within 6 seconds after opening the gas valve the ignition cycle is terminated. When the thermostat calls for heat the induction fan goes on the igniter lights the pilot and the burners ignite for a moment. Your furnace will still have a flame sensor but it will be over the burner s flame.
