The directions to access the charcoal filter are given in the basic operation manual on page 25 (page 27 of the PDF). First tilt the vent grille louver above the door of the microwave down towards yourself. (The vent grille goes across the entire width of the microwave). Next remove three screws, one on each side and one in the center top of the vent grille. Remove the vent grille. Place your finger under the bottom of the standard charcoal filter in the center of this filter. Use that finger to slide the filter forward. Since the replacement filter gets secured with two screws, remove the screws if you can't slide the filter forward.

The transformer is probably drawing too much power by a low resistance or a short somewhere on the secondary's side. The components on that side include the HV cap, the HV diode, and the magnetron all of which should be tested. I would try the cap first but make sure you discharge it before operating on it.

Purchase a replacement lamp from somewhere like espares or the like. It should be a standard E17 or SES 20Watt bulb.

I don't think the door film is part of the shielding - mostly the shielding is a sheet of perforated metal sandwiched in the door and covering the glass window. I think the glass film is just there to make it seem dark and mysterious until there is something going on inside. Try shining a flashlight through the door and see if there is in fact a perforated sheet... Microwave energy leakage meters are commercially available though they are less used these days as users have increased confidence. When a new microwave is obtained it is a good idea to accurately time the boiling of a measured quantity of water as a performance benchmark and then repeat the experiment at intervals - any significant extension of the time taken signals it is time for maintenance because the lost energy could be due to leakage...

This looks like it. It is a standard Philips compact florescent. You can get them at home Depot, or here https://www.repairclinic.com/PartDetail/Light-Bulb/FFV3420085S/4546044 ..

Hello Two options to try: 1) Press the Clock / Timer button 3 times 2) Unplug, wait a minute, then re-plug to power up with the factory settings. You will need to reset your clock and any favourite settings. This should work with all Panasonic Microwave models. Good luck

replace main board

Inner layer of a microwave door is part of the metal cage that keeps the microwave energy inside and prevents potentially dangerous energy leaks. To clean the inside of the glass the door will need to be dismantled - some doors dismantle easily and some don't and sometimes the door must be removed in order to dismantle... Some doors remove easily and some don't... It is very important the door is reassembled correctly and then tested for energy leakage.

Is there a quick fix to error h97?

Press exit

The most likely repair is a blown fuse or circuit breaker, either to your mains plug, or in the microwave. Test by plugging it into a different circuit. Beyond that, you would be looking at the power cord, then at the power supply circuit. If the clock is not at least displaying, you know it is probably not the controls. Go to Panasonic.com (or your local country equivalent) and click on Support, and you should be able to search for a user manual.

Never disassemble. Capacitors in over can kill if they discharge while working on oven even if oven is unplugged, yes. Unplugged

What does the start button have to do with opening the door?

check ddoor switch after remove cover

your door switch could be faulty

No one can tell you without looking at it. You need to ask yourself how old is, what did you pay for item what does a new similar model cost, You can look at other brands = Ask yourself what do you cook in it, do you need all the features s and the size, Personally i would replace it.

Need more info like the model number which is printed on the back. It should also show the wattage on the same sticker. If you can't find these and it was only a home microwave it was most likely only a 700 or 600 watt.
