Our spa has been working fine until yesterday when it began continuously trying circulate, then stutters (constantly trying to start but stopping) then goes quiet. It’s been been below zero for week here in Minnesota and won’t warm up until the end of next week. The water temperature is at 95 degrees so it’s not going to freeze but I’m worried the motor will go out and the it will. We put a space heater by the control panel, which is Balboa. See pictures. We can’t get a service call in this cold. What do we do?
