Microwave won't heat.

sounds like possible magnatron or diode thats the case its not worth repairing. but if your handy then google model nuber and get the part be extreamly careful because of the power capacitor holds extream volts. turn off and allow to sit 15min before working on

The problem is the magnetron, or the inverter board, "if 7 years old or less"

The problem is in the magnetron, "heart of the microwave oven" or the inverter board if the system is less than 7 years old.

That pop was the magnetron frying. This is a repairable problem, but feirly expensive, around $300 if you have it done by a professional.

Please rate my response if it was helpful to you.

Thanks, Repairman45.

Suggest you pull the plug out, remove outer cover and place a cup of water into the micro. Set power to minimum then switch on and take note if the fan works or not. If not, switch off immediately and have it replaced(magnatron will burn out if left to run without fan.)

Usually when it doesn't het there is a problem with either the magnetron or one of the power tranistors. You would have to get a shop to tell you what the problem is as it can be a few things. If you have warrenty either maytags or from the store just find out from the store/maytag where the repair depot is. They will either repair or replace it. If no warrenty then don;t do anything without getting an estimate. It may be just as cheap to buy a new microwave.

If it's less than one year old, it would be fully covered under warranty and you should contact the manufacturer to get it fixed free.

Some have longer warranties, and that will be covered in your owner's manual.

if everything works except the heating, it is most likely the mag tube is on its way out.........that is the most common reason for it not too cook.......since the microwave is a GE and it is 3.5 years old, i would say you are better off buying a new microwave, the mag tube starts at around $70.00 and up + the labor it costs too have a service person put it in........around another $60.00
