Maytag Refrigerator MSD2356AEB Freezer section too warm

Adaptive defrost control board.

This evaporator fan motor circulates cold air across the evaporator coils and through the freezer and fresh-food sections to maintain even temperatures. Replacing a failed or noisy motor restores proper airflow and dependable cooling performance.

• Drives the evaporator fan blade to move air over the coils and throughout the cabinet
• Helps maintain consistent temperatures between freezer and refrigerator compartments
• Failure symptoms include weak/no airflow, the fan not running, loud squealing/rumbling, or the fresh-food section warming up
• Poor airflow can also lead to frost or ice buildup on the freezer back panel

• Disconnect power before servicing; wear cut-resistant gloves and eye protection
• Access the motor behind the freezer's rear panel; use caution around sharp metal and evaporator fins
• Note wire positions; transfer the fan blade and any brackets/grommets from the original motor; secure wiring connections
• Ensure the blade spins freely; engage the door switch when testing and strong airflow after reassembly

This assembly contains the evaporator defrost heater and temperature thermostat that remove frost from the evaporator coil to help restore normal cooling. Replaces failed defrost components to help the fridge complete defrost cycles and reduce ice buildup. What it does:

• Heats the evaporator during defrost cycles so accumulated frost melts away
• Uses a temperature thermostat to open/close the heater circuit at the correct temperature
• Commonly replaces failed defrost parts when frost builds on the evaporator or the refrigerator runs continuously
• Helps restore normal airflow and cooling when defrost cycle has stopped functioning

• One defrost heater and thermostat assembly

• Disconnect power to the appliance before starting any repair
• Handle the evaporator and fins carefully to avoid damage; keep electrical connections secure and dry
• Follow the manufacturer instructions for routing and mounting the assembly
