Hello everybody, I'm new here. My Son just bought a used Whitfield Profile 30. I believe the old owner used a thermostat. I have not tried to put a thermostat on it (will try later today) but when we jumpered the terminals in the back, it makes the control board flash on and off about every second with a slight ticking noise. Does anybody know what this means and have we blown the control board? We took the jumper off and the lights come on the panel, but nothing happens, no motors, fans, anything. Just steady lights. Prior to this the fans would at least come on. Any help would be appreciated. Thanks in advance.
