When I program a time and press start it does not work. Then if I open and close the door it runs.

1. Defective control board
2. Defective door interlock

have you pressed the stop button twice when the door is closed to exit the program set for cooking

Probably one of the door switches.

There probably is a bad micro switch that needs to be changed.

The sensor errors are probably just from opening the door and interrupting the sensor cook cycle.

By the way, you should always press "Stop" before opening the door of a running microwave. Otherwise, the door switches will prematurely fail.

I would first check the door switches and their mounts. See this help file.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.



You can also download manuals, installations info, and parts lists here.

Remove the plug from the wall outlet and wait about 10 seconds before re-inserting it. The plug must be firmly inserted to transfer electricity to the appliance.


Open your home's circuit breaker box and reset the breaker if it has tripped and is set to the "Off" position. Simply slide the breaker over to the "On" position to fix a breaker that has tripped.


Plug a different appliance into the same outlet to make sure the outlet you are using is functional. Plug the microwave into a different outlet to see if this yields different results.


Press on the microwave door to ensure it is completely closed. The microwave will not function until the door is fully shut.


Press the "Start" pad on the display panel after setting the time. Failing to press this will result in the microwave not knowing that it should start.


Press the "Stop/Reset" pad on the panel if a program different from the program you want to run has already been entered into the system.


Press the "Clock" pad three times to turn off the demo mode. The demo mode will not allow the appliance to turn on and cook as it should.

This is a list of possible causes. 1. Defective triac or relay 2. controller is confused (pull power cord for a minute and see if it resets) 3.Defective controller or touchpad.

Did you pressed the stop/clear button? or disconnect the micro.. for a couple of hours and try again?
