Hello Todd, sounds like a power supply issue. Those unit have 2 separate power supplies in them, 1 for 24 volts and the second for all other control power. You can try to repair yourself but I would not recommend it as they incorporate many surface mount devices that require special equipment and skills to replace them. Give us a call at 800-575-5562 and ask for service. They will issue you an RMA number to send it in with. We will give you a free estimate of repair time and cost usually within 24 hours of receiving it. Good luck and thanks for asking Galco.
