Important Tips for Maytag Models

  • Maytag acknowledges temperature fluctuations as a common issue and recommends understanding potential causes and solutions.

Possible Causes

Poor internal air circulation within the fridge

How to Identify: Food or containers blocking air vents, noticeable temperature differences between areas/shelves

Part: Air vents and internal airflow pathways

Faulty or miscalibrated thermostat/temperature sensor

How to Identify: Temperature readings differ from an independent thermometer and fluctuate without change in fridge use; fridge struggles to maintain setpoint over time

Part: Thermostat/temperature sensor

Dust‑clogged condenser coils or impaired heat dissipation

How to Identify: Fridge runs longer cycles, coils visibly dusty, appliance feels hotter than usual at the back/bottom

Part: Condenser coils

Defective evaporator or condenser fan

How to Identify: Unusual fan noise or lack of airflow, inconsistent cooling especially after door openings

Part: Evaporator fan / condenser fan

Frequent door openings or poor door seal

How to Identify: Warm air entering when door is opened often, compromised gasket allowing air exchange

Part: Door gasket / user interaction
