Panasonic Panasonic inverter microwaves fault codes
The NN-DF, NN-SD and NN-ST families among others. Inverter models are where the H-code system and the lockout counter live, because they have an inverter power supply rather than a conventional transformer.
Codes on the Panasonic inverter microwaves follow the same Panasonic scheme as the rest of the range. Where a code behaves differently on this generation, the code page says so.

- H97An inverter or magnetron fault — and a counter. Panasonic state three H97 events disable the oven permanently, even after the faulty part has been replaced.Get it checked
- H95Panasonic’s UK support answer puts H95 on the inverter circuit; their service manuals decline to separate it from H97, H98 and H99 at all.Get it checked
- DDemo mode. The appliance lights up, counts down and appears to work while making no microwaves at all, and it survives being delivered to you.Usually simple to fix
- CoolingNothing is wrong. Panasonic publish this one plainly: the fan is clearing heat off the electronics, and the word goes away when it stops.Usually simple to fix
- H99The catch-all. Panasonic UK describe H99 as a general code for a problem with no code of its own; their service manuals file it with the magnetron.Get it checked
- HOTThe cavity is still too warm from the last thing you cooked for an automatic programme. Manual cooking still works, and opening the door speeds it up.Usually simple to fix
- ChildThe child lock. The keypad is dead, the door still opens, and on Panasonic’s UK models three presses of Stop/Cancel clears it — three presses of Start is what set it.Usually simple to fix
- ErrorThe same word means two opposite things on a Panasonic, and when it appeared decides which: a wrong button press, or stop using the appliance.Get it checked
- U14The water tank is empty. A user condition rather than a fault, and only combination steam models have a tank to report on.Usually simple to fix
- U50An overheat message with an unusual twist: on Panasonic multi-ovens the room being warm can cause it, not just the cooking you just did.Usually simple to fix
