Samsung ME16A4021AS Repair Guide
A value-tier Samsung over-the-range microwave with a ceramic enamel cavity. The enamel wipes clean easily, which meaningfully reduces the arcing calls these units generate.

Tech notes
Clean around the keypad before quoting a panel on SE or 5E. Grease creeping under the membrane holds a key down and produces exactly this code on a healthy panel.
