Question about Sharp R-1405 / R-140 Microwave Oven
I have found out that if I press ******* the upper right part of the door while at the same time pressing up on the bottom of the door, then everything seems to work OK. Does this mean that I need a new door switch? If so, How do I get at the switch to replace it? And where do I get a new switch? Thanks, Glenn
It may be a loose or broken door switch mount or possibly a bad switch.
I have attached (via e-mail) our safety, disassembly & door switch files.
Essentially you make sure it's *unplugged*, then remove the outer cover.
Then you can see inside behind the control panel where the door latches go into the chassis.
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.
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.
Just opening and closing the door a few times while observing closely will show you where the problem is.
I stock these switches and I can send you one for $6.00, or you can get one from a local appliance parts store, or some hardware stores and home centers like Home Depot or Lowe's.
Once you've looked all this over, please let me know if I can help further.
