Re: running with door open

I would say you have a failing door switch or the mount which holds your door switch is loose or broken. In most designs, it is the upper door switch that will produce these very symptoms when it is intermittent or its mount is broken or loose. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. Slamming the door, damage during shipping or transportation and sloppy manufacturing techniques or materials are the primary causes of trouble with the door switch mounts.

My microwave keep working when I open the door and it is stopping when I close the door.Then working normal but I cannot keep my door open, it keeps running. What can I do??

First, It is very very dangerous for a microwave to run with door open. The door is also a shield to protect you from the microwave radiation. There should be a safety interlock to prevent this from happening. DO NOT USE the microwave! Seek out professional repair or replace the unit.

Runs when door is closed,stops when open!Checked the three door switches;all good.The mw is 5 years old so anyone have suggestions as i would be thanking U in advance

It is possible that a relay on the control board has stuck in the closed position. You can try tapping the relays on the main control board and this sometimes breaks them free. It still may be one of the door switches but I would suspect the control board or possibly a stuck start pad on the touch panel.

Why microwave won't stop running unless door is open ?

Is it actually heating or just making noise and acting like it's heating? (put a cup of water inside and close the door.) IF it's actually heating, then you have a shorted relay on the main control board, and you will have to replace the board. IF it's just making noise like it's working, but it's not heating, then the problem is 1 of the door switches is not working right (it's either stuck open or stuck closed).

Kenmore 401.80083700 won't turn off

It is one of two things, a defective door switch, or the keypad control board has failed.

Model R-1460, when I shut the door it runs but doesn't heat up. What needs to be done to fix it?

Do you mean that when you close the door, the fan comes on? If so, it sounds like a bad door switch. Probably the secondary interlock switch.
This failure is caused by opening the door when the unit is in cook mode. On ALL microwaves, not just one or two brands.......
Be sure to push the stop button before opening the door to add or stir... Or wait for the cook cycle to end. (This is why microwaves have a two step function on the stop/clear button. Hit stop once to stop cook mode and twice to reset timer).
You should use an ohm meter to check all 3 switches. The switch can be either stuck 'closed' or physically closed but not 'making' electrically.

My spacemaker just stopped heating food. What do

This is a microwave, correct?

I suspect the door lock interface switch(es) are burned out. Unplug it, be mindful of the 25,000 volts in the silver thing. Check the micro switches (look where the door closes on the top right side, probably) two positions, normally open or normally closed. check them for proper operation.

Micro switches are the most common of microwave failures because most of us open the door while the machine is running causing arc at the switch and burning up the little contacts.

Turntable won't stop

Sounds like a door switch problem or stuck relay contacts on the control PCB. Do the light and fan run too or just the T/T??
