The handle on this over-the-range Maytag Microwave shows as never having been sold separate. No part number was on the lookup. The door DE94-01381M is a Samsung number so Maytag must have bought them from that manufacturer and put their name on it. We found the part #! Microwave MMV5207BCS - the door - DE94-01381M is no longer avail. You can use WPW10187840 handle only, successfully. We found it and were willing to take a chance at our expense if it did not work out. Our wonderful customer has confirmed that it fit great and saved him having to buy a new microwave and installing a new mounting bracket.
Awesome to know that a repair is still possible thanks to your research. Many thanks
