Replacement Observation

Wasnt completely sure this would match at first since the original component had worn out over time. Thankfully took around thirty minutes from start to finish and everything is working again.

Repair Note
5
After dealing with a situation where the older unit needed replacement part, we installed this replacement part. Everything powered back on correctly afterward. Worth verifying model number before ordering though.

Ended up ordering this because the appliance suddenly stopped working properly. Mounting holes lined up correctly during install. Appliance has been running normally since then. Would probably order again if needed.
