Came out today for a thermostat not operating properly. Upon inspection I found that the thermostat needed batteries. I installed new batteries (homeowner supplied) in the thermostat. The thermostat display light up right away. I called for ac and the thermostat clicked over but the system still would not operate. I took a look at the condenser and found that the low voltage wire was damaged most likely from the gardener weed whacking. I cut out the damaged section and wired the system back to normal. After a slight time delay the system fired up right away. The system is operating properly at this time.
