Cooling circuit
The compressor circulates refrigerant through the condenser, expansion path and evaporator to move heat outside.
REFRIGERATOR CARE
Reliable cooling starts with the right diagnosis.
From weak cooling and heavy frost to leakage and unusual noise, we inspect the full refrigeration, airflow and control system before suggesting a repair.
REFRIGERATOR SYSTEMS
Every cooling problem has a path to inspect
Temperature depends on sealed refrigeration, moving air, defrost control, door sealing and electronic sensing working together.
Air circulation
Evaporator and condenser fans maintain airflow. Ice, dust or fan failure can reduce cooling.
Defrost system
The heater, sensor and timer/control prevent the evaporator from becoming blocked by frost.
Temperature sensing
Thermistors report compartment temperature so the PCB can operate the compressor and fans correctly.
Door sealing
A damaged gasket or uneven door allows warm moist air inside, increasing frost and power use.
Drainage
Defrost water travels through a drain channel to an evaporation tray. Blockage can create internal leakage.
COMMON PROBLEMS
What we check during refrigerator service
- Not cooling: temperature settings, airflow, fans, start circuit and compressor operation.
- Heavy frost: door sealing, defrost heater, sensor and control timing.
- Water leakage: defrost drain, tray, water line and internal condensation.
- Unusual noise: fan blades, compressor mounting, vibration and ice contact.
- Continuous running: gasket leakage, dirty condenser, sensor accuracy and cooling efficiency.
