Panasonic Microwave H98 error code
The H98 error means your Panasonic microwave detected that the magnetron is not oscillating — no microwave energy is being generated. This is the most common serious error on Panasonic inverter microwaves and indicates that either the power supply has failed or the magnetron itself has stopped working. A power reset sometimes clears H98 if it was caused by a temporary power surge. If H98 returns the magnetron or inverter board will need to be replaced by an authorised service centre.
Common causes
- Power supply to the magnetron has failed
- Magnetron has failed and is no longer generating microwave energy
- Power surge caused a temporary fault in the magnetron circuit
- Inverter board has malfunctioned affecting magnetron operation
How to fix it
-
1
Unplug the microwave for 5 minutes and plug it back in to attempt a reset
-
2
If H98 returns stop using the microwave and contact a qualified technician
-
3
Do not attempt to open or repair the magnetron or inverter circuit — they operate at dangerously high voltages
