Installation Experience

After dealing with a situation where the appliance suddenly stopped working properly, we installed this replacement part. Repair solved the original problem. Would probably order again if needed.

Repair Outcome

The original component had worn out over time on our appliance ended up being caused by a failing part. Took around thirty minutes from start to finish and the replacement solved it.
