Component test · Range / OvenInduction boards rectify line voltage to a high DC bus and switch it at high frequency through IGBT transistors into a copper coil. Field work is limited to pan check, codes, input power, coil resistance and visual inspection; board-level repair is not a field job.
Component test · Range / OvenSelf-clean ovens use a small motor or solenoid with cam switches that tell the control the lock position. A lock stuck after self-clean is often a cooled-down timing issue; check the motor, the switches and the control output.
Component test · Range / OvenThe spark module makes a high-voltage pulse when an igniter switch on a valve stem closes. Constant clicking is usually moisture or a stuck switch; no spark is a cracked electrode, bad wire, or module.
