The M124, M417, and M437 are among JennAir’s earliest documented microwave ovens, sold under a simple letter-and-number naming convention well before the brand’s current JMC and JMV model numbers. A no-heat complaint on a microwave this age starts with the same two suspects our technicians check on any microwave – the door interlock switches and the magnetron – tested directly with the unit unplugged and the high-voltage capacitor safely discharged first.
