Common questions
What does an E1 or E4 error mean on a Samsung aircon in Kyalami Business Park?
E1 is a room temperature sensor error and E4 is an evaporator sensor error. Both are usually a failed thermistor or a connector that has corroded on the indoor board, and both are inexpensive parts once the correct one is identified.
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.
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.
