Question about In Microwave Ovens
Posted by Richard Mason on
SOURCE: Microwave won't start
If you're saying that the inside light won't come on when you opoen the door, then you probably have a bad door switch, most likely the upper one. The most common causes are opening the door while it's cooking instead of hitting the STOP pad first, broken switch mounts, and damage to or slamming the door. These switches are locally available at appliance parts companies. I have a helpful text file with critical safety information and info on diagnosing and replacing door switches. You can find it by doing a search on Yahoo.com (not Google) for microwave doorsw.txt

I would first suggest unplugging the oven for a few minutes to give it a reset. On Whirlpool brand microwaves, you will hear a series of beeps when you hit START if one of the following is true: - the control panel is not programmed correctly - the door is not shut - there is a problem with the door latch system - there is a problem with the control panel If you do not have your owner's manual, you can download it here: http://www.whirlpool.com/custserv/literature_search_results.jsp?searchTerm=RMC275PD#literror It doesn't sound like the control panel is locked. When the control panel lock is activated, you will see "Loc" and a lock symbol in the display and only the clock, timer, and oven light will operate. If that does not solve the problem, then you have oneof the other problems as listed above. If you need further help, please reply / add a comment here.

is usually caused by either a bad door switch, a loose door switch
mount (which are pretty simple problems to fix) or occasionally a
problem on the control panel.
Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.
Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.
There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.
The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.
Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.
One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.
If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.
You can find helpful exploded view diagrams and order parts by entering your full model number here.
There may also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.
If you only need a switch, you can order one from us for $5 postpaid.
If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.
We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Replace the fuse with a ceramic fuse from Home depot! costs less than $3 and it will fix the problem. I had all the same problems as everyone else, you name it my microwave had it! you must remember replace it with a ceramic fuse! not a glass one. I know people say its the switchboard and all that nonsence but I promise you, the fuse plays a majoe roll in the microwave not working properly. Even though it doesnt look broken, a junky fuse can cause your appliance to do very strange things. I replaced mine 6 months ago and it works like its fresh out of the box.

Tips for a great answer:
Hey JT Tai, I appreciate your post!
The symbol at the top left hand side of your display could be child lock symbol or vent symbol. If it is the child lock you should be able to press and hold the stop/cancel button down for 3 seconds to release the child lock.
If the light is on for the vent I would seek assistance from a professional for proper diagnosis and repair to be completed on your microwave. I hope this is helpful. -Matt
