Responded to a service call from a club member regarding a Nest thermostat showing error code E298—No Power. The homeowner noted that while they could still adjust the temperature on the thermostat, the heating system wasn’t responding. This issue started about 15 minutes prior to the call and was the first occurrence, with the system having been serviced during a tune-up in August and running efficiently since. Our technician inspected the wiring, checked the control board, and verified proper communication between the thermostat and the system. After addressing the connection issue, the system responded correctly, restoring full heating control. Another Churchville home back to reliable comfort.
