Seeing the screen of their smart thermostat go blank may cause homeowners in Harlem, GA some worry and consternation. Various explanations exist for this behavior, some of which are bigger issues than others. Here are some potential reasons why your thermostat’s screen would have suddenly gone blank.
Dead Batteries
The simplest explanation of all for this is that the batteries in your thermostat have run out of juice. Remove the old batteries, and replace them with new ones. Full functionality may immediately return.
If, instead of using batteries, your HVAC system draws power directly from your HVAC system, then it may have a loose wire and/or have tripped the circuit breaker.
Faulty Electrical Wiring
Because wires connect your thermostat to your HVAC system and enable communication between the two, the source of your trouble may reside in them. Some of these wires may be old, frayed, torn or otherwise useless. An HVAC technician will need to carefully inspect your wiring and replace whichever lines happen to be faulty.
Activating the Circuit Breaker
Despite charged batteries and robust electrical wiring, power may still fail to reach your thermostat. If so, something may be causing your thermostat and HVAC system to trip your circuit breaker.
If you’ve had the same circuit breaker or electrical panel for 30 or 40 years, then it may be too old to handle the amount of electrical power that your HVAC system needs to carry out ordinary operations. On the other hand, perhaps an airflow obstruction or mechanical mishap is causing your HVAC system to pull in larger-than-usual amounts of power.
Depending on the ultimate cause of the problem, you’ll either have to replace your breaker or fix your HVAC system. Annual maintenance can prevent many of the issues that might cause your HVAC system to trigger your breaker.
