    Who Can Fix the Touch Pad Panel for a Panasonic Microwave

    I have a Panasonic RV microwave that is close to 20 years old. The touch pad control panel developed a problem a few years ago that it does not recognize the touch when the inside coach temp reaches about 65 degrees F or lower. That is not an issue in the summer but it is in the fall and winter mornings before the heater and the sun warms things up. The workaround has been to rub the panel surface to heat it up or aim a blow dryer on it for a bit to get it warmer. Then it works like new.

    The panel has no outward physical buttons. It is the typical type with looks to be a smooth plastic sheet with graphics showing the functions and numbers.

    Unfortunately, a replacement part has not been available for years.

    Does anyone know of any electronics repair shop that knows how to repair these types of panels?

    I know some are thinking just go and buy a new microwave. The issues are: One, finding the right physical size. Two, most residential microwaves do not vent out the top which is needed to align with the vent screen in the cabinet. Three, most new models have a much higher power rating and draw to much power for my use. Most of my camping is boondocking off the grid where I have a lot of solar, four batteries and a 2,000 watt inverter. This is a 700 watt microwave and it is a great match with my electrical setup. The lowest possible new models I can find are 900 watt and the case size will require some cabinet work and the inside dimensions are smaller.

    Getting a new 900 watt is plan B but I would much rather get the Panasonic fixed as it is in great shape other than the control panel hassle.

    I checked with Dometic but they do not have replacement models for that class of microwave sold years ago. One would think there would be a replacement market considering how many where sold back then but I guess not.

    Thanks for any help on repair information.

    I can't help with a microwave repair, but if yours is built into the wall and you decide to replace it, you have to be careful that the back of the microwave matches up with the vent in the wall.

      Thank you Don for the advice.

      The microwave is set in what could also serve as a cabinet if it had a door and it is held in place by a metal trim kit that attaches to the front of the cabinet facing. The top part of the trim has slots. The vent is on the top of the microwave and it blows the air forward and that allow the air to exit out of the cabinet through the slots in the top trim piece and into the coach.

      The problem with the microwaves sold for normal home use is they vent out of the side rather than the top. That works fine sitting on a countertop but not if it is set inside a cabinet where is does not line up with a outside vent.

        We had to have our microwave replaced under warranty at six months after purchase. Our dealer had a difficult time finding a replacement that would fit. They ended up removing one from another Montana. Leave it to the RV industry to make a simple fix so complicated.
