Your thermostat is a powerful tool that can offer invaluable help for staying cool and comfortable in Marrero, LA this summer. Nevertheless, it can sometimes malfunction, and its screen can lose power. Here are a few reasons why your thermostat’s screen may have gone blank.
Dead Batteries
The simplest explanation for a blank thermostat screen is dead batteries. If batteries can no longer bring power to the device, then you won’t be able to see a screen display. The solution to this problem is equally simple: Replace the batteries. If your thermostat is hard-wired, one of the electrical wires may hve become loose. This is something a technician checks during maintenance.
Tripping the Circuit Breaker
Your HVAC system may be inadvertently activating your circuit breaker. If this happens, the breaker will immediately cut off electrical power to all parts of your HVAC system, including your thermostat. Various things may cause your HVAC system to trip your breaker, but since its compressor consumes more energy than of its other parts, you may want to ask a technician to check it for problems.
Another possibility is that your breaker is simply too old and dysfunctional to handle the power load that a newer HVAC system requires. In that case, you’ll have no choice but to replace the breaker.
Old Thermostat
Finally, your thermostat’s screen may have gone black because the device itself is too old and can no longer function. Newer smart thermostats may function reliably for about 10 years, while manual thermostats may be able, despite their significantly lower efficiency levels, to do so for much longer. Of course, if you don’t take care to provide your device with regular maintenance, it may fail considerably sooner.
The list of explanations we’ve given here is far from exhaustive. Your thermostat can malfunction and create trouble for you in Marrero, LA in many other ways. For help dealing with all these issues, call Caribbean Breeze Heating & Cooling today, and ask for our AC-related services.
