Wasnt completely sure this would match at first since the appliance suddenly stopped working properly. Thankfully fitment on our appliance was accurate and everything is working again.

Wasnt completely sure this would match at first since the older unit needed replacement part. Thankfully took around thirty minutes from start to finish and everything is working again.

Installation wasnt too difficult overall while replacing the old component because the appliance suddenly stopped working properly. Repair solved the original problem.

After dealing with a situation where the appliance suddenly stopped working properly, we installed this replacement part. No leaks or issues noticed so far. Worth verifying model number before ordering though.
