Just because you’re experiencing issues with your HVAC thermostat doesn’t mean there’s any problem with the rest of your HVAC system. In reality, blank thermostat screens are a common issue often easily fixed. Here are a few potential reasons your HVAC thermostat has a blank screen in Pinecrest, FL:
Loose Wiring
A recently installed thermostat may have a blank display if it’s struggling with loose or damaged wires. There’s also a risk that rodents in the walls damaged the wiring. It’s best to leave all electrical work to professional service technicians rather than risk shocking yourself.
Dead Batteries
Some thermostats don’t come with a common wire connection, meaning they use batteries as their only power source. When the batteries die, the entire thermostat turns off. Fortunately, there’s often an indicator on the display that tells you when the device has low power.
Tripped Circuit Breaker
If your thermostat doesn’t need batteries, that means it’s hooked up directly to your home’s electrical system. So when a circuit trips because someone plugged in one too many electronics, your thermostat will lose power and go blank.
Tripped Float Switch
Newer HVAC systems come with safety sensors like the float switch that turns off the thermostat if it detects moisture. In some cases, these switches can misinterpret their surroundings and malfunction. Routine maintenance during the year will minimize your chances of high-moisture problems like clogged condensate lines.
Outdated Thermostat
Finally, if you’ve tried to locate the problem and can’t find anything wrong, your HVAC thermostat may just need replacing. Older devices can suddenly stop working due to their many worn-out and compromised parts.
Your HVAC thermostat display may go blank if it has loose wires or dead batteries. It could also have lost power due to a tripped circuit breaker or float switch. Call RCI Air Conditioning Company to schedule a commercial or residential HVAC service appointment in Pinecrest, FL.
