The coupler just slips onto the turntable motor but they can be hard to remove. Try prying from opposite sides of the coupler but be careful not to damage the area around the coupler.

Yep--customer service

Sounds like a broken touch panel. Many of the pads are connected in a line and if a trace breaks you lose all the pads ran on that common trace. Are you looking to repair this your self? If not, you will need to find someone who services sharp or carries parts for them in your area

Changing the light bulb on your Sharp carousel microwave will allow you to have needed light inside the oven. Microwaves are not designed for consumers to change the light bulb due to manufacturer liability, but it can be done. Following the proper steps will ensure a successful installation. Step 1 Unplug the Sharp carousel microwave from the electrical outlet. Step 2 Locate the screws around the outer cover of the Sharp carousel microwave and unscrew all the screws. Step 3 Lift off the covering. Step 4 Locate the bulb and unscrew. Screw in your new bulb. Step 5 Replace the cover and screw back tightly. Once done, test your new bulb.

Before you invest too much time, look and see if the touch pad is still available. Sharp is pretty quick to discontinue parts right after about 5 years. There is a place called encompass parts. They are a distributer for Sharp, you micght check with them.

Un plug for a few minutes, plug back in, set the clock ( time of day) try again.

check the relays on the PCB, don't do it on the board but remove them outside and check properly.

Timer section is fubar. Reset the electronics to factory defaults and see if that cures the issue. If not, the timer section needs to be replaced.

internal short will do that could be a transformer or magnatron
