Torsion Spring - Black/White/Biscuit - Right side WP4451009

Remove side deco strips to remove screws that hold to cabinet. Pull microwave out and set on saw horses (power cable should be long enough to do this). Remove screws to top cover and lift enough to remove all connectors from the front panel pcb. Remove grounding wires from next top lid. Remove connectors from transformer on rigt side and the two connectionss at the rear fan assy. Remove top cover/vent assy. Remove the next top cover to get access to the light bulb assy. Use a cloth or kleenex while handling the new bulb as you replace it. The clip thta holds the bulb is easily released and use reverse procedure when assembling. For springs those can be replaced without removing the microwave from the cabinet. Remove the 2 screws that hold the door together accessed from the inside of the door at top. Pull door up to release from the clip at the bottom. Remove the broken spring and replace with new one. Use a screwdriver to help twist the torsion spring to clip into place. Replace door assy in reverse order.

A screw on the botton of the door was very inaccessible and difficult to remove. The rest of the process was flawless.

Just had to remove the screws holding the outer part of the door on (didn't have to take off the entire door). Using the other door spring (most models have two that cross) as an example, the new spring was fairly easy to place. Only problem is that the new spring was made from a smaller gauge metal and is not nearly as strong as the original, making the door feel heavier when opening/closing than before. The difference with and without the 2nd spring is barely noticeable. Had I known that they were making the parts cheaper now, I would'nt have bothered fixing it at all.

Removed door to see what happened to the spring, ordered new spring and door frame on line and replaced parts. Had to replace door frame as it broke while removing it.
