Whirlpool microwave - not getting power to the cooktop light
Hi there,
I've a Whirlpool Microwave (model MH1150XMQ-1). It is 1.5 years old. Recently the cooktop light bulb quit working and I simply thought it had burned out and went out and replaced it. The new bulb did nothing. Hmmmm. So I opened up the underside panel to check the socket for any problems. Using my circuit tester I determined that there was no power coming through the wires to the cooktop light socket. I plugged the socket into the wires that go to power the turntable and the socket indeed works fine (of course only when the microwave is engaged). So, I'm not getting any juice through the wires that clip to the cooktop light socket. I'm not sure how to open the unit up any further to check to see if something is visibly amiss with the board that feeds to the socket. This unit costs about $150-$170. Is this a problem worth fixing or is it something I can possibly fix on my own? Any input is appreciated. |

It can't be anything major but as someone else noted, microwave ovens are potentially lethal appliances to go inside due to the extremely high voltage and current available. Having said that, if the thing is unplugged for awhile and certain precautions are taken (discharging the high voltage capacitor if that is accessible when checking the light wiring), the problem can probably be found with just a multimeter or by inspection. It may just be a blown fuse. You didn't say whether the original light bulb was actually still good. That would halp narrow the diagnosis. --- sam | Sci.Electronics.Repair FAQ: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Sites: http://www.repairfaq.org/REPAIR/F_mirror.html Important: Anything sent to the email address in the message header above is ignored unless my full name AND either lasers or electronics is included in the subject line.
