Torsion Spring - Stainless Steel - Left Side WP4452395

All screws easily accessible except for one on bottom of door. It was tough to remove, even tougher to reinstall. Took some time and a unique combination of patience and small tools.

My biggest problem was getting parts. I ordered what was shown in the exploded view - a spring. I received one spring. When I took the door apart I found 2 springs both different (a left and a right). Only one was broken and the spring I received just happened to be the wrong one. It took a phone to work things out and get the other spring shipped.

It would be good if the exploded view showed both springs. It would be better if the part number would just include both springs. Come on, handling, packaging and shipping costs more than these simple springs. If one spring breaks there's a chance the other is about to go. Shipping the pair to customers so we can replace both just makes sense to me.

In another post it recommends replacing both right and left torsion bars. I took that advice and when it was taken apart it was apparent there had been stress put on the left hand spring, so glad I bought both. When the torsion bars arrived do not be alarmed one (right) is a much larger diameter than the left, went together easily. I thought taking the plastic guard off between the oven and the microwave first allowed me to see how the springs were installed and then I just kept all the screws separate to install back the way it came apart. Another set of hands did make this a much easier job. when you reinstall the bars it seems really tight but after putting the door back on and after opening a dozen times it feels like new again.

This was the 3rd time that our microwave door springs broke. Was tired of paying $100s to local appliance repair companies. Keep in mind that the form factor of the springs are not the coil type but rather straight rods in design, slightly short of the width of the microwave door. STEP 1 - remove the two (2) screws from the upper rear (interior side) of the microwave door. The front of the door panel can then be removed. STEP 2 - remove the black lower (plastic) vent cover located directly below the microwave door (4 screws). STEP 3 - remove the black plastic inner unit that surrounds the inner microwave door glass (there are 2 screws at the bottom). STEP 4 - Once this part is removed you will see two (2) horizontal springs that crisscross at the bottom of the microwave door. Take a photo of the spring positions for reference. STEP 5 - remove the broken springs, replace with your new springs and reassemble in reverse order.

Watched a U-Tube video that was helpful but did not address how fragile the plastic door frame was that the exterior glass front sat in / mounted to. The plastic door frame holes did not have metal inserts and plastic door holes were enlarged/stripped. Had to use larger screws. Also the plastic door frame was fragile and cracked in a couple locations. Luckily I was able to use duck tape to firm up the cracks in the plastic door frame. I tried to replace the plastic door frame but was not in stock/available.
That said easy to install the two Torsion Springs.
