Making a sound (I think from the fan) when operating

The only cause of clunking I can think of is the turntable motor not engaging the drive spindle of the platter properly. Remove the platter and see if the noise goes away.

No. That's just the way that model sounds.

I would try troubleshooting the "defrost circuit". The behavior sounds like the microwave is cooking in the defrost mode, where it actively cooks then stops allowing the food to rotate and the heat to spread then actively cooking again.

when microwave is running the fan sounds like it is grinding

It sounds like from the description when it is running the noise comes from the magnetron, some microwaves are louder than others, but this could be an early sign the magnetron is going.

this sounds like the magentron may be going. have you had any issues with it not heating? check your warranty book, some mags have a 3-5 year warranty, otherwise it's probably not worth repairing.

The fan blades may need cleaning or the fan motor may need it's bearings lubricated.

This can be caused when the internal cooling fan is not running or by a magnetron that is failing.

When I say internal cooling fan, I do not mean the hood vent exhaust fan which you can turn on and off manually.

I'm instead talking about the internal fan which comes on automatically whenever you microwave.

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

It is vital that the cooling fan runs, or the magnetron will be destroyed.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

You can 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.

All the good stuff is on the right side so it could be a lot of problems... most likely it is a the high voltage capacitor. does the microwave work at all? let me know and I maybe able to help?
