Service Assembly W11552018

If your microwave isn’t responding to commands or isn’t heating properly, the control board may need to be replaced. This replacement board measures about 4 inches by 8.25 inches and is responsible for managing cooking times, power levels, and other key functions. Common signs of failure include error messages, cycles that won’t start or finish, or a burning smell from inside the unit. Installing a new control board can restore your microwave’s performance—just be sure to unplug the appliance before beginning any repairs.
