Older fridge develops a thick sheet of freezer ice
A manual-defrost model may require scheduled defrosting, whereas sudden heavy buildup can also indicate poor door sealing.

What your refrigerator symptoms may mean in Lyttelton
Frost-free model warms every few days
Recurring evaporator icing may indicate heater, sensor, air circulation or door-seal faults.
Thermostat knob turns but does not change temperature
The sensing bulb, thermostat contacts or controls may be defective, but calibration and actual cooling performance should be verified.
Interior light fails while cooling continues
A switch or lamp circuit may be separate from refrigeration controls. We avoid treating a lighting complaint as proof the compressor is faulty.
TECHNICAL APPROACH
Diagnosing and repairing your fridge
Establish the cause
Our inspection starts with the refrigerator’s actual design: manual-defrost, cycle-defrost and frost-free systems do not behave identically. We test faults against the correct baseline.
Select the appropriate repair
After finding the cause, we discuss suitable repairs and available parts. We check the specific malfunction, including temperature response and any repeated ice formation.

OPERATING CONDITIONS
A fridge repair should restore reliable temperature
What else can affect cooling?
Manual-defrost and frost-free models should not receive identical diagnoses. The type of frost, frequency of formation and original design determine whether the ice indicates a defect.
Protect food while cooling is unreliable
Move perishable food to working refrigeration if cooling fails. After repair, verify temperatures under ordinary use.
DEEPER REPAIR GUIDANCE
Why fridge design matters before diagnosing frost
A manual-defrost freezer can accumulate some ice as part of normal operation, while a frost-free cabinet should manage evaporator defrost automatically. Treating both in the same way can lead to unnecessary parts or overlooked door problems. The control method also differs: a traditional mechanical thermostat responds differently from an electronic sensor and module. We identify the type before testing heaters, fans and temperature controls. On older models, any replacement thermostat must have the correct electrical and sensing characteristics; a vaguely similar control may not maintain the intended cabinet temperature. Evidence from a measured operating cycle is more useful than changing the dial repeatedly. A fridge that still lights up but stops cooling requires a different path from one whose only complaint is an interior lamp.
