Customer Questions and Answers for Cooktop Spark Module by Whirlpool

Deborah, Since the top burners work, gas supply is not the issue. Your range regulator / valve assembly 3196544 doesn't have an isolation valve, so gas supply to the oven burner is not the issue. When you select a temperature on the thermostat or ERC/Clock, the circuit closes and produces 120 VAC to the igniter, the igniter should start to glow, when the igniter glows long enough to produce 2.5 to 3.0 amps (round igniter) usually takes less than 60 seconds, the amperage draw causes the internal bi metal switch, in the safety valve to open and the burner ignites (the igniter produces approx.2300 dgrs. F. if operating properly). If the igniter glows, but does not produce the proper amperage, the burner won't ignite. 95 % of gas oven cooking or temperature issues are attributed to weak or inoperative igniters.
