You can fix it without the aid of a repairman. Simply unplug the microwave and remove the outer casing. There should be a few screws around the bottom edge and back panel. Once you have the unit open, look for where the power cord comes in. There should be a circuit board with a fuse mounted to it. This is your input line filter. The fuse should be a 20 amp appliance fuse that you can pick up at any hardware store (Lowe's and Home Depot both carry them). DO NOT op test with the outer casing removed. Potentials of about 14,000 volts are present in the high voltage network of a microwave oven. Close the unit up BEFORE you power it back up. Let me know if this helps.

It sounds like the keypad is worn out. The fact that you can get them to work sometimes by what direction you push on them, tells me that the contacts are not working correctly.
Did you have this problem prior to the fuse blowing or did it start after you replaced the fuse?
I don't believe the fuse blowing is related to the keypad problem. I also don't believe that you have a microprocessor problem because you say that the function buttons work but the number keys don't work right. If the microprocessor was faulty, it would not be able to read any of the keys.
The fact that the number keys are not working doesn't surprise me. When you go to cook something, you will press the number keys several times, while only pressing start or stop once. This is why your number keys have worn out first. These keys have a limited number of cycles (presses) and it sounds like its time for a new keypad.
Please let me know if I can be of further assistance to you.

SOURCE: keeps blowing fuses
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
Here is a link you or someone you know can use to test it, but please read the safety info:
You can order Panasonic parts from Tritronics here or by calling 866-779-5835, but if you don't find what you're looking for there, try here.

Chances are that either the diode or capacitor are shorted. Be very careful, the capacitor can store a charge and should be discharged first for safety. Hope that helps...
