DIAGNOSIS A complete power loss indicates a tripped thermal overload protector or a faulty power supply connection.
FIX First, check the power source. Unplug the cord from both the wall outlet and the back of the Opal unit. Wait 30 seconds. Firmly reconnect the cord to the machine, then to the wall outlet. Listen for a single beep and watch for the control panel to illuminate.
IF THAT DIDN'T WORK The internal thermal overload has likely tripped due to overheating. Unplug the machine. Move it to a well-ventilated area. Allow it to cool for at least 2 hours. Plug back in. If it powers on, the issue was overheating from poor air circulation around the rear vents.
HEADS UP The rear of the unit must have a minimum of 5 inches of clearance from the wall. Blocked vents cause the compressor to overheat and trigger a safety shutdown.
