Product review (3 stars): Frustrated that I even have to replace this
This is a frustrating purchase.  This door spring should not need replacement in the first place.  I had to order twice to get the correct part because first supplier substituted an incorrect part.  Need to use screw driver (2P) to take flapper off from left door, to then insert spring into its place.  This OEM part is not 100% perfect because the coil diameter is slightly larger than the original but my guess is the original was too thin, which is why they break.  The rest of the unit is fine
