Maytag Refrigerator MSB2154GRQ Freezer section too warm

The Run Capacitor is an OEM part for Whirlpool refrigerators. It is responsible for helping the compressor motor start and run efficiently by providing an extra electrical boost. This component ensures that the refrigerator operates smoothly and maintains the correct temperature by stabilizing the compressor's performance.

Causes of a bad run capacitor can include electrical surges, age-related wear, or overheating. When the capacitor fails, the compressor may struggle to start or run continuously, leading to inefficient cooling or a non-functional refrigerator.

Symptoms of a bad run capacitor include:

• The refrigerator not cooling properly
• The compressor not starting or running intermittently
• Unusual clicking noises from the refrigerator

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

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

Kit was recently redesigned by manufacturer. Photo shows older design. Instructions included.

Due to manufacturer changes this kit includes PTC start device, overload, electrical cover, jumper wire and instructions.

This refrigerator defrost heater and thermostat assembly restores proper automatic defrosting. The heater melts ice buildup on the evaporator, while the thermostat shuts off power at the right temperature to protect components and keep cooling consistent.

• Heats the evaporator during the defrost cycle to clear frost and ice
• Thermostat opens the circuit as the coil warms, preventing overheating
• Helps restore airflow across the coil and stable fridge/freezer temperatures
• Common symptoms: heavy frost behind the freezer panel, poor cooling or warm temps, fan noise from ice contact, unit not defrosting

• Disconnect power before servicing; remove freezer shelves/bins and the rear panel to access the evaporator
• Carefully defrost built-up ice; note original wire routing and clip locations
• Transfer any brackets/clips and mount the new assembly in the same positions
• Ensure connectors are fully seated and wires are clear of the fan and moving parts before restoring power
