Question about Whirlpool MH1141XM Microwave Oven
Where do I send the control panel if I would like that repaired?
Posted on Sep 08, 2008
This is usually caused by either a bad door switch, a loose door switch mount, 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. Other times, 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 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.

Tips for a great answer:
Check the mains power to the microwave before you check for power to the unit. If the program controller is not working , check
power - step down supply, the pads are responding- if not faulty pads- or the
door switches, if the switch contact are not good then it will not trigger the
processor to switch on the waveguides. If the lights or fan work without any
display or action of program being triggered to start then it can be a possible
fault on the main board or the processor. Sometimes insect secretion can short
the board and display panel and so the processor can work in such an erratic
manner. If so clean, solder and reset the board. Now identify the parts by

If there is no heating
please do not switch on unless you have confirmed the fault. It is possible
that the Magnetron is faulty, the temperature cut off is faulty or the main
capacitor is short. It is also quite possible that insect can get into the oven
and create soft spots. When you switch on these will create a short and make
the voltage jump and in the long run damage the magnetron. Check this link to
know how a microwave works:
So Remove cover after disconnecting , check for dirt/moisture in
the cabin, if so wipe clean and dry, check the magnetron and area clean and use
an jet air to clean off. Check the wave guide covers, if food had deposited
then it must be checked or replaced. See link: http://www.espares.co.uk/advice/microwave/a/5/1146/how-to-replace-a-microwave-guide-cover.html
