When door is shut light is still on and wont operate


The switch is either broken and stuck in the on position or the pin on the door that pushes the switch to the closed position has been worn or broken. Check the alignment of the door to make sure that it is closing correctly.

The part that holds the door switches inside the oven is broken; can the part be replaced


Yes this can be stuck using a instant glue if the broken pieces can be found. Usually this needs to hold the switch and lock in alignment.
So try this out , you can remove the front panel and get access to this assembly.

Door catch broken - door will not close. no sign of a broken piece. There was a bang and the catch just doesn't hold at all. door swings open


Door catches.

One of the latches has broken off and is not lifting the other latch clear of the housing. Remove from any power source, remove the cover of the cabinet. Slacken off the clamp mechanism and ease the clamp over the guide to allow the door to open. When a new door lever is in place, the door may be easily adjusted by slackening off the screws that clamp the door catch/actuators in place whilst holding the door closed and then tightening the screws. The rear of the door may be adjusted by slackening the lower door hinge screws and adjusting as required.
I hope that helps.



Door switches

If one of the door interlock switches is not switching properly, that can cause the turntable/light to come on even though the "Starts" button has not been depressed due to the wiring of the switches.
Check for faulty door switches and/or contaminated actuators.
I hope that helps.

The door is shut tight. the light stays on so u cant use it. i have unplugged it let it sit plugged back in same thing. model r-1460a


The problem is almost certainly a broken upper door switch mount .

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.

If the switch mount is broken, it's usually more economical and safer to add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Then you can see the switches and mounts.

If you only need a switch, you can order a universal type here for $5 postpaid.

Microwave lights up and counts down, but does not operate


You have a failed secondary interlock (bottom door switch) or its mount is loose or broken.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually 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.

MICROWAVE TURNTABLE


Does it turn for just a moment or does it keep turning?

If it's just for a moment, that's normal.

If it stays on, either your top or bottom door switch is sticking or it's door switch mount is loose or broken.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

One test that sometimes helps is to gently lift up 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.

Microwave automatically comes "on" when door is closed, but no heat.


I have the R-1460 in the same series with the identical symptoms. After reading MicrowaveSvc's solution I started taking apart to view the door switches and found the upper door switch to be the problem, but not a switch failure a support failure. A small bottom plastic support post that holds the switch in place was broken (probably from repeated use/abuse) allowing the switch to move when the door hooks were engaged, thus not actuating the button switch. Since the problem was mechanical rather than an electrical bad switch, I made a small support arm for the switch from an old plastic mechanical pencil and glued it in place to hold the switch in its correct position. Problem solved, microwave works! Thanks to MicrowaveSvc's description of door switches.

Smasung MW7490w door/turntable problem


It's probably a defective door switch, probably the upper one, or the mount which holds the switch is broken. Opening the door while cooking (without first hitting the STOP button) is the primary cause of door switch failure. There are plastic mounts inside the microwave which hold the door switches and onto which the door hooks latch 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. Usually it's not a loose screw, but instead a broken tab on the switch holder, allowing the switch to rotate just out of position.
