Whirlpool WP4452396 Microwave Door Torsion Spring (Right Hand) OEM Part

Removed the Microwave from the wall, then had to almost completely disassemble the sheet metal surrounding the microwave unit itself. Lots of screws and wires to work around. Takes 2 people to remove the microwave and set it on a stand outside of the wall unit. Once you get to the light bulb, the replacement is easy, just very challenging to get to the light bulb.

Ordered the correct parts, which arrived in 2 days. Took a couple of hours as this sucker is a huge pain, but some offered tips did help. Second time these have broken on this oven....

One of the most difficult parts is simply locating the correct replacement parts. Your website helped me though I tried unsuccessfully to locate a stronger replacement.You simply require a good phillips screwdriver - I find the socket style with replaceable bits work better. To change the springs and lite bulb you need to first remove the 2 side SS trim pieces and then the bottom SS trim piece. Then you have access to the 2 screws on the bottom that retain the entire microwave. removing them allows you to slide out the entire microwave a few inches. aT THIS POINT FWD YOU NEED TO SUPPORT THE DOOR ITSELF AS IT CAN BE DAMAGED. Then there are 2 screw inside the oven door on top and 2 more outside on the bottom holding the door brackets. removing them all allows the outer SS face to come off and allows access to the 2 bottom plastic trim screws. Removing these you can remove the trim and get to the torsion springs.These are difficult to describe but you should be able to look at the old ones to see how they fit to install the new ones - a pair of needle nose pliers helped here. The lite bulb is reached by sliding out the unit more and lifting off the insulation - it has spring retainers that are fairly straight forward,

Replaced broken spring

Fix was easy and the part was exactly what I needed.
