We have a Carrier Termoidistat thermostate, about 9 years

Customer Question

We have a Carrier Termoidistat thermostate, about 9 years old. The system was not on. We walked by the thermostat and it was blank. We checked the breaker. It was on. What would cause a thermostat to go blank if it is not the breaker and the system was not on. It is a wired not battery operated system.
JA: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?
Customer: That is my question. Can it be simple and just a thermostat problem or is it always a larger HVAC problem
JA: Do you plan on doing the work yourself?
Customer: Only if it is simple and not a safety issue not to call a heating contractor.
JA: Anything else we should know to help you best?
Customer: The system was not on when the thermostat went blank.
