FFFF is not mentioned in the user manual, but there may be some helpful information or contact information in it.

PANASONIC Dimension4 NN C988W Operating Manual And Cook Book


This is not certain, but it may be a part that is expensive to replace according to this other web site for a similar model Panasonic oven. That person said their microwave was still working.

Good day, I have a Panasonic Dimension III Microwave/Convection Oven 1983
Model NE-9910A.

I went to use it today and when I entered to nuk my coffee a FFFF display appeared where the clock normally appears. I went and found my operating instruction booklet and it indicated to "stop/reset" which I did. Next it indicates to contact a Panasonic Servicecenter. Can you help me out? ps. It still works great!!!!!

FFFF means that your display control board has an internal short. The only way to fix the problem is to replace the display control board which is no longer available. If you really wanted to fix the microwave you'd need to remove the display board and mail it to a place like Appliancetimers.com to have the part refurbished. The cost to have the part repaired is usually about $200-250 or so.

There is no such mode microwave oven for Panasonic. Your's should be an exact duplicate.

Error Code/Message - Oven - F1 Error Code - F1 E5

Control displaying F1 E5:

There may be a problem with the Oven Control, or the associated wiring.

Power unit down by turning off the circuit breaker(s) for one (1) minute.

Power unit up by turning on the circuit breaker(s).

Monitor the oven for one (1) minute to ensure the error code does not display again.

Verify oven operation.

All electronics work but microwave won't heat.

Hello Karim,

I went to the Panasonic website - - (http://www.panasonic.com/)

Clicking on Commercial Food Service - Customer Service links, I got

If I can be of further assistance, let me know. If this helps or solves the issue, please rate it accordingly.

Thanks in-advance for using Fixya.com,

Not sure of the TT series models but for the NN series models the procedure is as follows:-

If "Child" is displayed in the display window, then the child safety lock is on.

To remove the child safey lock, press the "Stop/Reset" button 3 times in fairly short succession (less than 3 seconds). The time of day or just the Colon sign (:) is then displayed

If you later want to apply the Child safety lock, then, when the time of day (or colon sign) is displayed, press "Start" 3 times (again in short succession).

Hope this helps

In most cases, this is a problem with the inverter or a bad magnetron.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here.
