Repair Outcome

The refrigerator would reboot intermittently on our appliance ended up being caused by a failing part. Had to double check model compatibility first and the replacement solved it.

Helpful Product Insight

Wasnt completely sure this would match at first since the control panel stopped responding randomly. Thankfully took around thirty minutes from start to finish and everything is working again.

Installation Experience

Connector alignment matched better than expected while replacing the old component because the refrigerator would reboot intermittently. Cooling performance seems stable again.
