Common questions
Why is ice building up at the back of my Defy fridge in Sunninghill Office Park?
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.
What temperature and humidity should a wine cellar hold?
Twelve to fourteen degrees Celsius at 60 to 70 percent relative humidity. Drift outside that band usually means a failed humidistat, a leaking vapour barrier or a unit sized for a smaller cellar.
Can you work after trading hours?
Yes. Retail, restaurant and office work is routinely scheduled at night or early morning under a permit-to-work so trading is not interrupted.
