I suspect the magnetron or high voltage transformer, and either part's cost or labor would probably be about the same as the cost of a new comparable unit.

SOURCE: Microwave does not heat food placed in the center of the turntable. Leaves a cold spot in the middle of the food.

This is normal. That's why I always recommend to my customers that the food be placed slightly off-center on the turntable. An analogy I refer to is stirring paint: If you stir paint with a stick by simply rotating the stick in the center of the can, it's far less effective than pulling the stick around an imaginary circle halfway bewteen the center and the edge.

check the protector connected at the capacitor and at the magnetron coil windings, check using an ohm meter.,meter should read to zero

I have the same problem. Everything seems to work except it doesn't heat up food.
I remember last time when it was working. I pressed the start botton before I closed the door. So it didn't start automatically, and I pushed start and it worked(it still heat up the food), but it doesn't work now. Help Please!!!
I have a Whirlpool Gold GH5184XPQ.

Thanks in advance

It's most likely the Magnetron. The are not very easy to install and quite expensive. Older models magnetrons cost about 80 bucks from GE. It's probably not something you would want to try and repair yourself. Call a GE service person.
