Microwaves contain high-voltage components that can retain a lethal electrical charge of up to 2200 VAC -- even when the microwave is unplugged. Repairs and adjustments, even minor ones such as replacing fuses, can cause microwave leakage. A microwave shielding leakage test should be performed after any microwave service.
It is for these safety reasons that we are unable to guide you in microwave repairs and instead recommend that you carry the unit into a Sears Store or Sears Repair Center for service by a qualified repair technician.
You can visit this website for information on the nearest drop-off locations in your area: Sears Home Services.
We thank you for your understanding in this matter and hope we can help you with other questions and repairs in the future.
