Priority attendance

Long Freeze Cycles

Freeze cycles take far longer than the manufacturer's timing.

We diagnose in order of likelihood rather than replacing parts speculatively, starting with the water circuit and harvest cycle before any sealed-system work is quoted.

What we check first

Likely causes

  • Dirty condenser or high ambient
  • Scaled evaporator
  • Low charge or restricted metering device
  • Water temperature too high
  • Failing compressor performance

How it is tested

Diagnostic sequence

  • Clean condenser and re-time the cycle
  • Descale the water circuit
  • Read pressures, superheat and subcooling
  • Log inlet water temperature
  • Assess compressor differential

FAQs

Frequently asked questions

What causes long freeze cycles?

The usual causes are dirty condenser or high ambient, scaled evaporator, low charge or restricted metering device, water temperature too high. Which one applies is settled on site by measurement, not guesswork.

How quickly can you attend in Johannesburg?

Priority attendance applies to this fault. Call-outs are run from the central Johannesburg base, which keeps attendance windows short for kitchens in the northern and central suburbs. Call 069 268 0988 for the next available slot.

How is it diagnosed?

Clean condenser and re-time the cycle; Descale the water circuit; Read pressures, superheat and subcooling; Log inlet water temperature; Assess compressor differential.

Is this common on block ice machines?

Block plant is the slowest ice to make and the slowest to melt, which is why it survives in transport and fishing duty. On block ice machines in Johannesburg we see this fault regularly, usually alongside overdue descaling.

Which service will fix it?

Ice Machine Replacement normally resolves it. One to three days depending on access and configuration.

Can we keep operating in the meantime?

Sometimes — where the fault is a water-side problem the machine can often be run on reduced output until parts arrive. Where a compressor or leak is involved we advise buying in bagged ice while the repair is completed.
