Hey,
About a year ago I purchased a custom cold plunge from the Australian company Odin. I had no previous problems with the tub and it worked great. Recently when I attempt to power on the tub using the controls on the converter, it will turn on for a few seconds and then trip and turn off. I tried resetting the outlet and even called an electrician to come replace the outlet which changed nothing. At this point I am assuming it is a problem related to the converter. It has ample space for ventilation and still powers on for those few seconds when plugged in. Sadly Odin has since gone out of business, being a small specialized company. If anyone has a recommendation please let me know.
