How These Products Work

Refrigeration systems rely on several key components to maintain consistent, safe operating temperatures:

  • Defrost heating elements remove ice build-up on evaporators, preventing airflow blockages and improving cooling efficiency.
  • Drain-line heaters stop drain pipes freezing, preventing water blockages and leaks inside the unit.
  • Thermostats and temperature sensors regulate internal temperatures, triggering cooling cycles as needed.
  • Fan motors circulate cold air throughout the cabinet, ensuring even cooling.
  • Compressor crankcase heaters maintain compressor efficiency in low temperatures by preventing refrigerant migration.

Each refrigeration spare plays a crucial role in maintaining reliable temperature control, ensuring food safety compliance and protecting perishable goods.

Ideal Use / Application

These refrigeration spares are ideal for:

  • Commercial kitchens in restaurants, pubs, cafés and hotels
  • Retail environments such as supermarkets and convenience stores
  • Cold-chain facilities and food storage warehouses
  • Catering operations using chilled food prep areas or mobile refrigeration
  • Maintenance engineers responsible for repair and servicing of commercial cooling equipment

Whether for scheduled maintenance or emergency breakdowns, these parts ensure essential refrigeration equipment stays operational and efficient.

Important Considerations & Safety Notes

  • Only qualified refrigeration engineers should install electrical or mechanical refrigeration parts.
  • Incorrect installation can cause temperature instability, equipment failure, or safety hazards.
  • Always check compatibility using your equipment’s model number and manufacturer specifications.
  • Replace parts at the first signs of wear - issues like ice build-up, unstable temperatures or frequent cycling often indicate a component fault.
  • After replacing components, ensure the equipment is tested, calibrated and checked for correct operation.
  • Never bypass or modify safety devices such as thermostats or overload protectors.

Customer Reviews

"Good replacement

30 year old Zanussi fridge in the shed used as a spare at Christmas decided last year to either freeze everything or to thaw it. It was ready for its final journey to the recycling centre until the brother in law revived his much newer Bush fridge with a replacement thermostat. I copied and the result is a Zanussi fit for another 30 years, I hope. A bit of a fiddle to do but not too bad for an amateur."
