microwave will not heat food

Unless an expensive unit replacing the Magnatron and or Inverter that powers the unit will cost more than replacing the unit itself.

OC, Over current

99% of the time you have over current with a Microwave, it is typically the Magnatron, then the HV transformer, as first suspect. If you plugged the unit directly into the wall outlet it would probably blow a fuse. The Magnatron is the large item that makes the Microwaves.

You are speaking of an Inverter so you probably have the Microwave in an RV. RV Microwaves are typically expensive because they fit in small places and it you may want to have it repaired.

I have a whirlpool model MH7140XFQ and we got a guy to come and look at it and he said the Mag. tube and the circuit bars were broken. Which would be more expensive to change the broken things or just change the microwave

He is referring to the magnatron tube which is the heart of the microwave. Probably more expense than you would want to put in to it.I would recommend replacement unless it is a high end model. Hope this helps

I think I broke my baby...

If it's dead, it's probably a blown fuse or maybe a blown thermalcouple fuse. a bad magnatron won't make the unit apear dead unless its blowing fuses.

Hope that helps..
