Samsung ME21M706BAG Repair Guide
A large-capacity over-the-range microwave with sensor cooking and a ceramic enamel cavity. The enamel interior genuinely helps — it wipes clean rather than holding baked-on splatter, and clean cavities arc far less often than neglected ones.
Common problems & typical repair costs
| Problem | Likely cause | Typical fix | OEM part # | Typical cost |
|---|---|---|---|---|
| No heat with everything else normal | Magnetron or high-voltage diode | Professional high-voltage repair | — | $180–$430 |
| Dead unit, blown fuse | Door interlock switch failure | Replace interlock set and fuse | — | $120–$280 |
| Panel showing a stuck-key error | Grease under the touch membrane from the cooktop below | Deep-clean the panel; replace the membrane if it persists | — | $0–$390 |
| Sensor cooking inaccurate | Humidity sensor fouled | Clean the sensor and exhaust path | — | $0–$300 |
| Weak extraction over the cooktop | Filters loaded or ducting restricted | Clean filters; verify duct and damper | — | $0–$220 |

Tech notes
SE and 5E on Samsung over-the-range microwaves are so often grease-related that cleaning around the keypad should always precede a panel quote. The unit sits directly in the steam from everything cooked below it for years.
