They all come in standard widths. Any 30" microwave should be fine.

Whirlpool MH2175XST
1.7 Cu. Ft. Over-the-Range Microwave with 1,000 Cooking Watts, Warm Hold Cycle and Sensor Cooking Cycles: Bisque 4.6 quick specs
Style: Over the Range
Width: 29 7/8 Inch
Depth: 15 3/4 Inch
Height: 17 1/8 Inch

On this microwave, you just need to enter the correct cooking time and power level. This will clear the previous time and power level that you entered. (This works since you need to use the Options button to do multi-stage cooking.)

The manual for the Whirlpool WMH53521HZ is available on the product site: https://www.whirlpool.com/kitchen/cooking/microwaves/over-the-range/p.2.1-cu.-ft.-over-the-range-microwave-with-steam-cooking.wmh53521hz.html . Scroll down to the Manuals & Guides section or use the link and expand the section.

I hope this helps.

(Note: the -4 indicates a minor difference between versions. Sometimes it indicates the color of the microwave.)

It could be the possibility of the bulb about to go out or dust in the fan

its the high tension fuse .9 size its long

If the sound is a bit like angry bees but muffled, then the magnetron is on its way out.
Sorry.

It depends on if it is just a loose component that needs tightened up or if it has started failing. it will require some investigation and trial and error to resolve. I have had some success in resolving vibrations and some were real challenges. It is a matter of isolating the noise maker and seeing what can be done.

The magnatron may need replaced..(this is what makes it cook)

as it is over the range it may be goop from cooking that has it stuck in place, its like hard glue.
some kind of spray to eat grease may be what you need.

PLease open the housing of turn table motor at bottom of the oven and check for the AC input voltages on motor terminals as specified on sticker on motor. for no heating please check fuse between high voltage transformer and high voltage capacitor. Also check high voltage Diode and Magnetron.Please please don't try to measure voltage on terminals of magnetron.
