When the freezer becomes extremely cold while the fridge starts freezing items like vegetables or drinks, it indicates a problem with the shared cooling system. This often results in wasted food and higher energy bills.
What usually causes it
Malfunctioning thermostat or temperature sensor
The thermostat may be reading the fridge compartment incorrectly, forcing the cooling system to overcompensate. This can lead to an overcooled freezer and frozen fridge food.
Replacement costs £60–£150.
Damaged damper or air control
The damper valve controls how much cold air reaches the fridge. If stuck open, cold air floods the fridge and freezes items while the freezer becomes overly cold.
Repair costs £70–£150.
Control board errors
Modern fridges use electronic boards to regulate temperature. If the board malfunctions, it may send incorrect signals to the compressor or fan.
Replacement typically costs £150–£300.
