Common Issues Reported by Users

  • Faulty temperature control thermostat
  • Blocked air vents or improper airflow
  • Defective evaporator fan motor

User Suggested Solutions

  1. Check and replace the temperature control thermostat if faulty. To do this, unplug the refrigerator, locate the thermostat (usually inside the fridge), and test it with a multimeter. If it shows no continuity, replace it with a new one.

  2. Inspect and clear any blocked air vents. Ensure that nothing is obstructing the airflow inside the fridge. If the vents are blocked, remove any items and clean the area to allow proper air circulation.

  3. Test the evaporator fan motor by listening for its operation when the fridge is running. If it is not running, replace the fan motor. This involves unplugging the fridge, removing the back panel inside the freezer, and replacing the fan motor.
