Evaporator plate replacement where scale pitting, refrigerant leaks or physical damage stop a plate from releasing ice cleanly. In Kengies this is luxury gated estates work on evaporator assembly systems, attended within about 65 minutes of dispatch.On Sub-Zero equipment specifically — built-in refrigeration columns, wine storage and integrated units — the faults we see most in Kengies are evaporator fan failure in freezer section and control board and sensor faults.Every visit starts with a full diagnostic and a written quote before any part is fitted.Complex intercom access. Ice Machine Repairs bookings in Kengies are logged against Block 12 so we can allow for power availability on site.

Refrigerant data
| Gas | Classification | Suction pressure | Discharge pressure | Typical use |
|---|---|---|---|---|
| R134a | HFC (A1) | 80-140 kPa at -5 degrees C evaporating | 900-1 200 kPa at 45 degrees C ambient | Wine cellars, display cabinets, medium-temperature commercial refrigeration and some heat pumps. |
| R404A | HFC blend (near-azeotropic) | 40-60 kPa (approx. 2-4 bar) | 1500-1900 kPa | Older commercial ice machines, cube makers, ice bins and blast chillers |
| R448A | HFO/HFC blend (low GWP) | 50-75 kPa | 1600-2000 kPa | Modern commercial ice machines, cube and flake units, coldroom retrofits |
Common questions
Can a built-in Sub-Zero be repaired without removing the joinery in Kengies?
In most cases yes. The units are designed to be serviced from the front through the grille and toe panel; full de-racking is only needed for sealed system work.
Do you charge a callout fee?
A standard callout and diagnostic fee applies and is quoted upfront. It is credited against the repair when you accept the quote.
There is water on the floor under my ice machine, can you find the leak?
We trace it wet rather than guessing: inlet valve weep, split distribution tube, blocked machine drain or a backed-up bin drain all present the same way. The water side is pressure-tested before we recommission.
How urgent is a slow harvest cycle?
Treat it as urgent. A stalling harvest leaves the plate frozen solid, output collapses and the compressor runs against high head pressure, which is how a cheap solenoid fault turns into a compressor replacement.
