After dealing with a situation where the buttons were no longer reacting correctly, we installed this replacement part. Noise issue disappeared after replacement.

Replacement Observation
4
Mounting holes lined up correctly during install while replacing the old component because the control panel stopped responding randomly. Cooling performance seems stable again.

Repair Outcome

Used this replacement after the buttons were no longer reacting correctly. Needed basic hand tools only. Repair solved the original problem. Would probably order again if needed.
