Question about Sharp R-403HW Microwave Oven
Hi... i was boiling some water and had the microwave set at 5 mins. with about 1:30 mins to go the microwave fan and turntable stopped working.
the timer and light still work... just not the turntable and fan. i've noticed that if i press upwards on the door and hold it, everything starts working as normal... if i let go, the timer continues counting down and light stays on, but that's it.
the door looks fine, cosmetically speaking... so what could be the problem?
This is usually caused by either a bad door switch or a loose door switch mount.
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 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.
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.
