Customer Questions and Answers for Bake Ignitor by Whirlpool

Jerzy, the spark module WPW10511278 would need to be tested for voltage during a bake cycle. At the connection J1, the red wire at pin 6 would need to be tested for 120 VAC when the unit fails. If there is voltage, the next step would be testing from the red wire at pin 1 to the orange wire at pin 2 for 8 to 18 VDC. If there is not voltage, the spark module has failed. If there is voltage, the safety valve W10919226 would need to be replaced. However, if there was not 120VAC at the first test, the oven sensor W10833885 would need to be tested for resistance when the range is unplugged. It should measure 1100 Ohms at room temperature. If the sensor tests good, the main control WPW10340317 would be the likely cause of failure.
