  • NG Oven won`t heat up?

    Posted by chefhenryclay on September 16, 2023 at 7:28 pm

    My NG oven burner will not work. The pilot flame stays lit but the burner won`t ignite. I checked the wires on the gas valve and all are connected tight. The pilot flame is strong and the temp. dial clicks when you turn it but no burner flame comes on.

    What else comes to mind in order to get this oven back working?

    What make and model of oven?

    Electric or mechanical thermostat?

    Hydraulic or millivolt safety valve?

    Hydraulic or millivolt safety valve? millvolt

    Just a moment...

    I would lean towards a clog in the gas line or a faulty gas valve. a click on the thermostat when you turn the dial means it is calling for heat or you turned it off. depending of the rotation direction.

    Best bet would be using a meter and checking the thermopile millivolts, then verifying that the thermostat is calling when it clicks.

    Ok, the pilot is staying lit, so the safety valve is open. And the thermopile is making power. Now you have to look at the thermostat to be opening main burner gas valve. Now is the main burner valve is 750 millivolt.

    So you’ll need a multimeter to check that the coil is not open and that the thermostat closes and the power output of the thermopile.. Also check the wiring and connections on the main valve and thermostat. Then measure the voltage at the Safety valve with the thermostat turned off. It should be about 750 millivolts DC. Now turn the thermostat up for heat call and measure the voltage at the main valve. Main valve to be above 500 millivolt. If voltage is low, inspect the pilot burner to be adjusted right. You can monitor the voltage as you adjust it. If you have proper voltage, remove the wires of the main valve and ohm the coil winding. Open will be infinity. If it has continuity, reconnect and turn the thermostat up. then tap on the valve from the top with a screwdriver handle to see if it is stuck. If it then opens, order and replace the valve. If you do not have power at the main valve, ohm the thermostat. Off, infinity, on, zero ohms.

    Most often it is electrical connections on the valves.

    You all were correct about the thermopile not opening the gas valve. After receiving very low readings via volt meter from the thermopile connections to the gas valve, I replaced it. Gas oven is back on line! Thx for the advice tech town techs
