I have a Hot Springs Landmark hot tub, bought new in 2002. Not getting power to the heater. Well, first the heater relay board shorted out and blew. I bought a new heater board and installed it today, but the heater is still not working. The no fault heater seems ok, tested it with meter and got about 10 ohms between wires. The circulation pump is running. On the main board the green light is on and the red light is on. Still getting no voltage to the heater though. Could the new board be bad or maybe a relay on main board. Anyone have any ideas on what could be the problem. Thanks.
