Question about Whirlpool MH1140XM Microwave Oven
Manufacturer: Whirlpool Model no: MH1140XMB-1 The other day, I went to replace the range light and ended up breaking the screw connector from the bulb (the installer glued the bulb in place.) so I flipped the relay for the microwave, used my pliers to remove the rest of the bulb, (didn't have a replacement bulb so I just screwed the cover back on.) and then flipped the relay back on. The control panel came up like it had lost power, so I pressed the clock button and re-entered the time. My wife then tried using the oven, and it let her enter the cooktime, and even hit start. At which point the oven should come on, nothing happens, but the timer starts counting down like it's cooking. Upon investigating other functions, it also appears that the vent fan isn't working, and upon checking the voltage to the empty bulb with my multimeter, it was 4VAC, no matter how the switch was set on the control panel. Any tips would be much appreciated.
This is a problem with the control panel assembly, which we repair nationwide for $32.50 postpaid. Sometimes the bulbs short when they fail, and that damages the control board. This also can happen when bulbs are removed or installed without first unlugging the oven or turning off the breaker.
