Jim L. for Model Number WFG510S0AB1 Hi, My oven is not lighting consistently. The spark ignitor will click but not light the oven. Sometimes it will work after the gas dissipates and we try to light it again. Replaced the ignitor with a new one this morning but we have the same issue. Also, once cooking at 450F it heated up and then did not hold temperature and cooled off. Would this be the spark module? This stinks only 13 month old oven?
Answer Jim, The spark module WPW10331686 is one possibility. but you also need to check the gas valve solenoids for resistance and voltage from the module. when the oven is attempting to ignite there should be 8 to 18 volts DC across the gas valve solenoids from the spark module. and each solenoid should have a resistance of 215 ohms resistance across the terminals. You may want to operate the oven for a few minutes before you start testing the voltage and resistances, That way the wek part would have time to malfunction to make the tests a bit easier, and results more accurate.
