Customer observations (examples)

• Larder/fridge section freezing — salad, drinks, or dairy items in the fridge compartment becoming partially frozen.
• Back wall icing — large blocks or sheets of ice building up on the rear wall/evaporator panel.
• Fresh products frozen solid — fruit, veg, or fresh meat unintentionally frozen in the fridge section.
• Very low temperatures on a thermometer placed mid‑shelf (e.g. -0c).
• Motor seemingly continuous — a steady hum/vibration for long periods without normal cycling off.

If you can, note approximate cabinet temperature (centre shelf), where the ice forms, and whether the motor appears to run continuously.

Thermostat replacement

Uh‑oh! It looks like there may be a problem with your thermostat.

You can verify a potential thermostat issue if you notice any of the following:

• Over‑cooling while the motor runs continuously — stored products become excessively cold or almost frozen.

If you’re facing these symptoms, replacing the thermostat is often a straightforward and cost‑effective fix that keeps older units running well.

Quick checks

• Confirm the thermostat knob isn’t set to maximum by mistake (turn down slightly and monitor).
• Ensure items aren’t pressed tightly against the back wall.
• After any adjustment, allow the appliance a few hours to stabilise before re‑checking.

Customer observations (examples)

• Food not cold enough — milk/soft drinks not chilled; frozen products defrosted.
• High cabinet temperatures — thermometer on centre shelf reading well above normal (e.g. > +15°C in a larder section).
• Frequent door openings/large warm loads — temperature rises and takes a long time to recover.
• Compressor behaviour — runs continuously without any cooling.
• Unusual frost pattern — ice on one small area, or no light frosting where usually expected.

If possible, note cabinet temperature (centre shelf), how often the motor runs, and any unusual noises.

Quick checks

• Thermostat setting — ensure it’s not set too warm; turn to a cooler setting and allow several hours to stabilise.
• Ventilation (installation) — ensure adequate ventilation; avoid enclosing the compressor space on non-integrated units.
• Warm product — avoid loading large amounts of room‑temperature food at once; chill in stages if possible.

Is the appliance operating in a high ambient temperature?

High ambient indicator: Treat the surrounding air as "high" at approximately +25°C or above (inside the room/cupboard/galley around the appliance).

Tip: Maximise energy efficiency by avoiding overloading with warm fresh food, especially during hot weather. Keep the interior well‑organised to reduce running time, ease strain on the appliance, and promote optimal performance while minimising power use.

Common observations in high ambient

• Longer run times — motor runs for extended periods to remove heat.
• Slow pull‑down after loading warm items.
• Warmer compressor and hot condenser surfaces.
• Frequent door openings quickly raise cabinet temperature.
• Under‑cooling complaints during heatwaves despite motor running.

Quick checks & good practice

• Stagger warm loads — avoid filling the cabinet with room‑temperature food all at once; chill in stages.
• Organise interior — keep items clear of the back wall and internal airflow paths between products.
• Improve ventilation — ensure installation allows for clear ventilation to the top and both sides of the appliance; provide a minimum clearance of around 25 mm on non‑integrated appliances.
• Location — if possible, keep the appliance away from direct sun or heat sources; ensure adequate clearance around cabinetry.
• Door discipline — minimise open time; check gaskets seal properly.
• Thermostat — set appropriately; allow several hours for changes to stabilise.
