Question and Answers


Panasonic Microwave model nn-t990sa


I am sorry you are experiencing difficulties with your Microwave. Microwaves contain high voltage internal components that can retain a lethal electrical charge even when the microwave is completely unplugged. Door repairs and adjustments, even minor ones, can cause microwave leakage and a microwave shielding leakage test must be performed using a survey meter after any microwave service. I strongly suggest that you have this repair handled only by a qualified service technician. I have provided a link To Sears Home Services if you decide to schedule service. If you think it may be cost effective to just replace the unit, I have also provided a link to the Microwave section of to price out what a replacement would cost.

Thanks for contacting I am sorry you are having a problem with the microwave. We do not give out much repair information on microwaves because of the dangers of repairing them. The microwave generates extremely high voltage. The capacitor can store this voltage even when the unit is unplugged. Any repairs to the door or handle could cause leaks in the door. These are all extremely dangerous. I hope you understand our policy on microwaves. Our number one concern is your safety.
