Australian Whitegoods Questions? Ask a Technician for Answers ASAP
Hi, welcome to Just Answer. My name is ***** ***** I look forward to helping you! If the main board was replaced with no results, there is likely a problem with the relay on the compressor. When it stops cooling, do you hear a humming or buzzing sound, followed by a heavy click? What do you have to do to get the unit cooling again?
If the temperature is returning to room temp, there is a problem other than the beeping. I will place your question back to the list for others to see, maybe another will be better suited to assist you at this point.
