Why won't my interior microwave light turn off and my microwave won't start?

It sounds to me that your door switches aren't working.Your oven is protected by a couple of switches that engage when you open or close the door.They control a couple of safety features and also your interior light.One of them seems defective.

My whirlpool microwave combo #4450785A stopped working the light went out and it says door on it please help it is not starting and says door

The door latch could be defective. Your microwave is designed to operate only when the door is securely latched closed.

Simple issue here,there is a micro switch that shuts the light off when you close the door ,it may also open a circuit depending on yuor particular switch that lets the microwave think the door is open.Not hard to fix if you are handy,remove the screws to the sheet metal cover ,locate the switch and make sure that the switch is being made when you close the door.Could just be it is loose,could be the pin that hits this switch is missing,broke or out of adjustment.In any event,do this with no power on ,also these devices can still store power so be careful here .If you are not careful you could get seriously hurt so remove plug and or call someone that has some electrical experience this is totally at your own risk.

Whirlpool Microwave Oven (Model MH1140XMQ-0) interior light will not turn off

ther is only 2 causes for this. one is that the door latch has failed and the only way to repair is to get the entire door assembly. the other is a switch that is on the inide of the unit just behind the user control. i do stress that, if you pull the outer cover off to access the inner switch, you need to be very careful about what you touch, and unplug the unit. there is a capacitor inside the unit that will shock you and it does hurt. the high voltage side of your microwave is about 20,000 volts

Start button an 1/2 buttons on keypad no work in my GE JVM150H microwave. Interior light also stays on.

The door has latch switches that are part of the protection and operation when door is closed, is the new door identical and switches match up {same number} if everything checks and the door switches are all working, the door needs to be checked for alignment, if it's out a small margin the switches will not operate properly.

F6 appears on my Whirlpool Over Oven Microwave, Model GH7145XFB0. It will not let me perform the self-diagnostic test. When the door is closed, the light goes out and the unit begins the "cooking process"....

If it starts cooking as soon as you close the door,try unplugging it for a minute then try again. If it does the same its probably a defective triac or relay which is inside the microwave.

Door-activated power switch is loose and/or has a short

Fixed this problem! The door latches were greasy and sticking in the closed position (i.e., pushed down so not latching and engaging fully when the door was closed) and this created the problems described above. Solution was to squirt some Windex into the latch holes to dissolve the grease. The switches popped back into position (must be spring-loaded) and the door closed and latched properly, allowing the oven to function properly. I swabbed out the hole with a q-tip, let it dry for 20 minutes and all is well.

Interior light won't go off

Asta, the cavity light runs through the secondary door switch which is the top one. Sometimes during shipping these switches get knocked loose from there mounting and the oven starts doing some funky things. You can remove the control panel and get a look at these switches, they will be to the left. See if they are all secure in their mounts. Also check the p-4 harness on the board, re-set it. This is where the cavity light relay harness is. If it's new, call for warranty service...high voltage here, be back.
