Common questions
Why is ice building up at the back of my Defy fridge in Sandhurst?
That is almost always a defrost circuit failure: the heater, bimetal or defrost sensor. The ice blocks the evaporator, airflow drops and the fridge compartment warms up while the compressor runs constantly.
How quickly can a coldroom be back at temperature?
Once the fault is cleared, a well-insulated coldroom pulls back down within two to four hours. We advise on stock protection during that window.
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.
