Question about Maytag Microwave Ovens
The interior (cooling) fan is critical to keep the magnetron cool. If it fails the magnetron will overheat.
This can cause it to trip the thermostat or thermal fuse, which will make the oven dead. If the magnetron is overheated too long of too often, it will be destroyed.
By contrast, the hood / exhaust / vent fan is important for keeping steam and grease out of the controls of your microwave.
The hood fan can fail due to problems with the motor or the control panel.
If you or someone you know wants to look into this, we have critical safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa.
We even have a video on our site that shows you how to safely & easily remove the control panel assembly in less than 5 minutes so you can check out your oven.
You can usually find helpful exploded view diagrams and order parts by entering your full model number here.
There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.
