    Is it possibly shutting off after exactly 22 seconds?

    Do you have your user manual? Is there a section about child locking your microwave?

Hi, there are three issues that will cause a no heat situation in a microwave. these issue are a failed Magnetron, busted cut-off fuse and, failed diode.

I recommend checking all these area that are located inside the microwave for faults.

The most common issue will be a failed Magnetron.

The diode and, fuse will be located on the noise filter assembly.

SOURCE: Panasonic Inverter NN-V673S microwave- shuts off after 2-30 secs

If the screen is showing a fault number or a number you havent seen before then its probably a program fault which can't be fixed. Check that the vent holes on the back of the oven aren't dirty and ensure that the whole oven is clean inside. Sadly it sounds like a program fault which cant usually be fixed by the owner though.
Finding a Panasonic oven repairer in the UK shouldnt be a problem though. My parents had a simlar problem wth their Panasonic Inverter oven, called the UK customer services and Panasonic contacted an authorised repairer in Scotland to visit them. Call customer services on 0844 844 3868.
If the call out charge exceeds £80 then you're probably better off buying a new oven.

I would say either the high voltage transformer or a component on the inverter board has failed.

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.

SOURCE: my microwave says "child" and won't play anymore

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

SOURCE: microwave runs 3 sec then shuts off.

mtystufquit - We've already discussed this by chat & e-mail, and if and when you need further help, please let me know.

"If the digital programmer circuit / controller does not get a feedback signal from the inverter for a period of 3 seconds, the controller will stop the cook cycle."

ddmdavid - you probably have a bad door switch or door switch mount. Please see these links.

Error message "chiLd"


There is a Child Safety lock-out feature on some microwave ovens. This enables the user to lock the keypad to prevent children from playing with the control panel. The model number you have this question posted under has this feature enabled/disabled by pressing and holding the "CLEAR/OFF" button for 3 seconds. However, the display reads "LOC" when the feature is activated. I suspect your model number is different because of the display indication you are receiving. Review your owner/operator manual for how to disable the child lock feature. If you no longer have the owner's manual, or if you still have questions, please post back with your BRAND NAME and MODEL NUMBER, so that I may be able to provide you with better assistance. I hope this helps you.

CHILD SAFETY LOCK


If the model number you have this question posted under is correct, to cancel the child lock safety feature all you need to do is press and hold the zero "0" button for at least 4 seconds. The "LOCKED" indication will go away and you should hear two beeps. The instructions are listed on page 11 of the owner's manual. If you no longer have a manual, you can download or print a copy for FREE at managemyhome.com. Just type in your model number under the "Manuals" link.

If you have questions, or if your model number is different, please let me know. I hope this helps you.

Everything on oven appears to work, but does not heat.


from what your describing it sounds as if you have burnt the antenna off of the end of the magtube if this is the case if your microwave is no longer under warranty due to the cost of the part you may be better off to purchase a new microwave.
