Oven Fan Not Working? Gas Oven TroubleshootingOne of the spark ignition switches might be defective. The spark ignition switch sends voltage to the spark module. When the electrical contacts inside the switch close, power flows to the spark module. If the spark ignition switch fails with the electrical contacts closed, the switch will send continuous voltage to the spark module. To determine if any of the spark ignition switches is defective, use a multimeter to test each of the switches for continuity. If a spark ignition switches shows continuity at all settings, replace it.
One of the spark ignition switches might be defective. The spark ignition switch sends voltage to the spark module. When the electrical contacts inside the switch close, power flows to the spark module. If the switch contacts are wet or stuck in a closed position, the switch will send continuous voltage to the spark module, no matter where the dial is set. Each of the switches can be tested individually to determine if they are shorted. If a spark ignition switch is shorted and is not wet, or if drying it out doesn’t solve the problem, replace the switch.
Some burners have a flame sensing circuit that sense the burner flame through the spark electrode circuit. If the burner has a good flame but the igniter keeps sparking the orifice holder may not be damaged and not grounding properly. Inspect the holder to see if it's misaligned and replace with a new one as required.
On some models the spark module will automatically shut off the spark when the burner lights. If the burner cap is not on properly the the gas or flame may not get to the igniter causing continuous sparking. Ensure that the burner cap is on properly.
The spark switches under the burner knobs have to be dry to work properly. If water boils over or is spilt on the spark switches, they can short out, causing the burners to spark even when the switch is turned off. Unplug the Range and let it dry out for a day.
The range's spark module sends pulses to each spark electrode to create a spark to ignite the gas. If the spark module has a flame sensing function it will automatically stop sending pulses to the electrode when the burner lights. If the electrode is defective the spark module will not be able to sense the flame and continue to allow the electrode to spark after the flame has ignited. Inspect the electrode to see if it's visibly damaged or dirty and replace if necessary.
The spark module provides power to each surface burner spark electrode. If the spark module fails, it may cause the burners to spark continuously. However, the spark ignition switch is more likely to be at fault. Before replacing the spark module, first test the spark ignition switch. If the spark ignition switch is working properly, consider replacing the spark module.
If the range's oven burners keep sparking all the time and the spark igniter appears to be in good condition, it's likely the oven control board is not sensing that the burner has lit and is continuing to send voltage to the sparker. Since control boards are difficult to test, you should confirm other more likely defective components are all working properly before considering a control board replacement.
The surface burner cap needs to be in good condition and positioned correctly on the burner base for the gas to be ignited. If the burner cap is rusty or damaged it will not make good contact with the burner base which can cause the burner to spark continuously without igniter the gas.
If the range's oven burners keep sparking all the time and the spark igniter appears to be in good condition, it's likely the control board is not sensing that the burner has lit and is continuing to send voltage to the sparker. Since control boards are difficult to test, you should confirm other more likely defective components are all working properly before considering a control board replacement.
If the range's oven burners keep sparking all the time and the spark igniter appears to be in good condition, it's likely the main control board is not sensing that the burner has lit and is continuing to send voltage to the sparker. Since control boards are difficult to test, you should confirm other more likely defective components are all working properly before considering a control board replacement.
