Replacing inverter board for my sharp R-2130JS microwave

http://kitchen.manualsonline.com/manuals/mfg/sharp/r1850a_16.html

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.

The clock is part of the control board and cannot be repaired as a separate item. Most replacement control boards costs as much as
a new microwave.

No heat can be a bad inverter board (power supply) or a diode or the Magnetron itself.

The problem maybe the magnetron, or the inverter board if 7 years old or less, and possibly the keypad control board, by the time you add parts and labour cheaper to replace the microwave oven in the long run.

How do I set the clock on my Smart Microwave Oven?

This model uses an inverter to product high voltage.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Sharp-authorized servicer.

Don't use it! Unplug it and take it back to the dealer-sounds like a loose wire or short.
