Replacement Observation
Installed this when the buttons were no longer reacting correctly. Had to double check model compatibility first. Repair solved the original problem. Repair turned out easier than expected honestly.

Compatibility Feedback
Wasnt completely sure this would match at first since the buttons were no longer reacting correctly. Thankfully fitment on our appliance was accurate and everything is working again.
