Question about Sharp Microwave Ovens
Sounds like an electrolytic blew, but it could be any nuber i=of things. Usually when one element fails, others are damaged and are failing as well, such as the magnetron.
If it is an inexpensive table-top microwave, it would be less expensive to replace it with a new one.

Waleed, Since the microwave is going through all its motions we can feel safe that the oven and magnetron thermostats are ok. If they were bad you would not have a display. Just inside the control panel to the left, you have 3 switches which the door activates. A primary (top switch) a secondary (bottom switch) and a monitor switch (middle). If the primary or secondary switch is not closing when the door is shut, you high voltage side will not activate, therefore no heat. If the monitor switch failed or found either the primary or secondary switch closed with the door open, it would blow the main fuse and the oven would be dead. Therefore Im leaning on either the primary or secondary switch not operating correctly. When checking these switches, unplug and discharge the capacitor. This is high voltage. Good luck

In most cases, this is a problem with the inverter or a bad magnetron.
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 Panasonic-authorized servicer. You can find one here.

SOURCE: Error code ee1 on sharp r-22at
EE1 on a Sharp commercial microwave is magnetron 1-related failure.
It may be a bad connection or relay on the control board, a bad magnetron, a bad high voltage diode, etc. - anything in the high voltage circuit for the #1 magnetron.
We have the service / repair manual for a similar model and have uploaded it to our site here to help you.
It will give you safety info, step by step help in disassembly and troubleshooting tips, but do not rely on the part numbers shown in that manual.
You can find part numbers and order parts from Encompass here or you can call them toll-free at 866-779-5835.
Most computers will open the manual automatically, but you may need the free Adobe Reader

Hello, I just purchased a Sharp Carousell II convection microwave oven, also built in 1990, serial number 212806. I think the model number is R18244, but part of it is worn off. Can anyone tell me how to get a manual for it? I have never cooked with a convection oven before.
