Repair Note
5
Had to replace this after our control panel stopped responding randomly. Took around thirty minutes from start to finish. Noise issue disappeared after replacement. Part quality feels reasonable compared to original one.

The control panel stopped responding randomly on our appliance ended up being caused by a failing part. Took around thirty minutes from start to finish and the replacement solved it.

Wasnt completely sure this would match at first since the buttons were no longer reacting correctly. Thankfully needed basic hand tools only and everything is working again.

Had to replace this after our control panel stopped responding randomly. Connector alignment matched better than expected. Repair solved the original problem. Worth verifying model number before ordering though.
