Richard G Portland , OR September 11, 2015 Appliance: Model EMMERSON 8993SB MICROWAVE OVEN Microwave would not start Found a stuck open interlock switch in the door prtection circuit. I found you eqivalent switch at 20% cost of the Emmerson exact replacement to be as good as the original. I order extras because there is 3 identical interlock swithces in the door protection circuit, you know haw people "slam" the doors shut. Thank you for your expediaence and great odfering of several cost effective substutes. Supertech, AKA techenstein Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
