Induction coil and IGBT power board (trained techs)

Induction 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.

Oven keeps heating when turned off or overheats past setpoint

This is a fire hazard: turn the breaker off first, then diagnose. On electronic controls the usual cause is a relay on the control board whose contacts have welded closed. On dial ovens it is a stuck thermostat or selector contact. Less often a shorted sensor or harness is to blame. On gas ovens, a burner that won't shut off is a gas-valve problem and goes to a licensed gas technician.

Gas oven lights then goes out, or keeps re-igniting

First separate normal cycling from a fault: the burner shuts off and relights to hold temperature. On glow-bar (hot-surface) ovens, a weak igniter can glow but pass too little current to hold the safety valve open, so the flame drops out. On direct spark ignition (DSI) ovens the module must sense the flame through the ground path; a poor ground, reversed polarity, a dirty or cracked electrode or a failing DSI module makes it lose the flame and re-spark. The gas valve, pressure and orifices are licensed gas-technician work only.
