A "zapping noise" usually indicates a problem in the high voltage circuit. If it's an inverter oven, it should have provided you with a fault code. If a non-inverter, the most likely causes are a shorted high voltage rectifier or bad magnetron. But there are many other possible causes.

Found this Panasonic post in the Samsung section!
If it moves just a tiny bit when the door opens and then stops, that's normal.
If it keeps running when the door is open, that's usually due to a bad door switch or broken / loose door switch mount.
If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and
disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk

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.

If everything works, but the microwave oven does not heat, this is commonly caused by a failed magnetron. The magnetron is essentially, the heart of the oven. This is what produces the RF energy that heats your food.
Here's what you need to determine whether or not its worth fixing:
1. You will need to uninstall the oven from over the range in order to replace the part (you will need to do this anyway, if you decide to buy a replacement oven).
2. You will need to ensure the oven is UNPLUGGED before servicing anything inside the cabinet. You will need to remove the exterior case in order to access the magnetron. There are several websites that you can use that illustrate how the oven is assembled:
searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
If you've never repaired an appliance on your own before, a microwave oven is usually not a recommended appliance to start with. Some models can be rather involved in taking apart.
3, The magnetron replacement part number for the model you have listed is WB27X10305. The average cost is about $80. NOTE: I found the part listed for the best price at appliancepartspros.com at a cost of $76.
You need to decide whether or not $80 and the amount of labor involved is worth the effort as opposed to replacing the entire oven at a higher cost and less labor (other than the installation). Review the parts illustrations at the recommended websites to see if this is something that you may be able easily take apart and reassemble.
If you have any questions, please post back and let me know. I hope you find this information helpful
CAUTION: DO NOT operate a microwave oven with the exterior cover off. The voltage inside the High Voltage network where the magnetron is installed can exceed 3,000 volts.
Testimonial: "Hi jsrock516 - thanks for your expert information. I don't think this is something we can fix on our own and as you said probably cheaper to replace. "
