TLDR; What is the best way to splice wires together that will be moving?
I purchased a Kenmore Elite 106.51773510 refrigerator in March 2017. I had a few issues with the ice maker during my first year of ownership that were covered under warranty (turned out to be alignment issues and NOT an icemaker issue). Last week, I was surprised (and frustrated) to find out that the ice maker stopped working again. I investigated the issue and was able to locate the root cause of the problem. The wiring harness that comes from underneath the freezer door and goes up through the door and connects to the icemaker (and other components) is broken. See attached photo for reference.
I was able to conclude on the root cause of the failure for this wiring harness. When the freezer door is opened and closed, the wiring harness is pinched and folded over. Over time it has broken (think bending a metal hanger over and over again until the metal fatigues and breaks).
At this point in time, I have identified that the wiring hardness is NOT available for purchase and the only way to repair this failure is to replace the door which costs about $1200. The wiring harness is permanently installed in the door. But replacing the door with the SAME wiring harness will result in the same failure over time.
So what I am looking for here is some assistance on fixing this issue. The only economical solution that I can come up with is to splice the wires together. But when splicing these wires together, should I solder the wires or butt splice them. When I complete the repair, I am going to have to extend the wires underneath the refrigerator in order to eliminate the pinch point. Any suggestions or feedback is much appreciated.
Update 2019.05.01: I have purchased the following materials from a local electronics store for repair.
This is the plan.
- Stagger cut the wires (to allow for space for the butt joints)
- Complete butt joints on staggered cuts
- Shrink wrap each wire
- Shrink wrap the whole wire
- Re-route the wires to eliminate the pinching
