Arrived on site for no cooling. Went to check out the thermostat the thermostat had no power to it. Took off the thermostat and checked for voltage from R and C, got nothing tried jumping in G to R,, no reaction. Went upstairs to the Attic. Popped open the panel to check for power. L1 and L2 was giving 240 volts. Notice that the plug connected from L1 and L2 to the system was deteriorated. Check if the Transformer was receiving anything, no voltage was detected and Transformer. Checked if the fan blades of the blower wheel move freely, they did. Unrelated but found another issue in the attic, the boiler water outtake was leaking, about a drop of water every minute. Made sure the valve was shut tightly but it kept dripping.
