What Does Error H98 Mean?

The H98 error code on your Panasonic microwave combi oven indicates a malfunction in the inverter or magnetron circuit. This typically causes the microwave to start and then stop after 20-30 seconds, with no heating of food. The control board fails to detect a normal operating signal, leading to this internal fault. It's essential to address this issue promptly as it may require professional repair or part replacement.
