Question and Answers


Ran empty MT4155SPB5 Whirlpool Microwave oven 1.5 cubic foot


Thank you for contacting with your questions about your Whirlpool Microwave. I am so sorry to hear it isn’t working. I know what a time saver the microwave is and know you want to get it working again quickly. In this case, because it stopped working after being run without anything in it, I suggest you have it tested and repaired by a qualified technician.


We do not give advice on repairing microwave ovens because they are inherently dangerous to service. Microwaves contain high voltage internal components that can retain a lethal electrical charge even when the microwave is unplugged from the outlet. You need special equipment to work on a microwave starting with an anti-static wrist strap grounded to the microwave to even test components in it. Even minor door repairs and adjustments can cause microwave leakage, and a microwave shielding leakage test MUST be performed using a survey meter after any microwave service.


For these safety reasons I strongly recommend having this repair completed by a qualified service technician. You can schedule service online at or by calling 1-800-4-MY-HOME (1-800-469-4663). Here at we love to help you with your repairs, but our expert advice is that microwaves are just too dangerous for a do-it-yourself project.


Thank you for your understanding in this matter and I hope we can help you with your future questions and repairs. Thank you for choosing Sears and using our service.
