Last season my spa's GFCI plug mysteriously melted late in the season so I really wasn't paying attention. I got a new plug but the spa trips off on startup. The heater pumps water then the blower comes on for a second and it trips. I took the panel off, took a blow dryer to the inside to eliminate condensation along with each plug and outlet (male/female) and even tried starting unplugging the ozonator, blower, pump, and heater. Still it trps once either the pump or blower is selected. At least after drying it out with the hair dryer now the heater will stay on until the spa attempts to cycle and the blower and / or pump comes on - then it goes off. Any ideas?
