I have a Balboa CL501x1 . NO heat. I have 120 volts on the heater. SHould be 240. NO error codes on the display. I get the 120v from the right side of the board. I have 120v immediately after turning on the breaker. During the 6 second trial, the heat light comes on, but I still have only 120v at the heater, and no amp draw. Heater is 4kw and shows 14.5ohms. I've checked the back of the board. There was one post that was cold, but that was re-soldered. I'm thinking the board is bad. Any ideas?
