Question about Frigidaire FMT144G1 Microwave Oven
The microwave has a high voltage transformer that raises the 115V coming from your wall up to about 3000V that then powers a magnetron tube responsible for heating your food. If their is a short, this transformer will discharge making aloud pop and often fry anything it discharges into. Because this is more than enough to kill somebody, there is a fuse that will blow. As a result, while the fan and light are working and as a result your microwave appears to run normally, in actually it's just the fan and the light. Anything the would make heat is disabled and potentially damaged.
Two issues you would need to address this. First, the fuse will have to be replaced. Secondly, you will need to identify where your short is. Personally I recommend taking it to a certified repairman, or buying a new one.
