Your thermostat is integral to managing your heating, ventilation and air conditioning (HVAC) system. In this article, we’ll explore common reasons why your thermostat screen could go blank and how you can rectify the situation.
6 common reasons your thermostat screen is blank:
The solution could be as simple as changing the batteries. While a battery change differs by the model as the removable battery compartments are different, it becomes pretty straightforward when you gain access to the batteries.
Thermostat batteries usually last a while before needing a change, except in cases of battery drain or your device shipping with defective batteries. As a result, you might need to opt for a battery change.
Doing so allows you to rule out the battery if the problem is unyielding after the swap.
And other times, the answer is simply flicking a switch. Chances are that your thermostat is on the same circuit breaker with a device that draws too much power. A surge from the high-power device can cause the breaker to cut off power to your thermostat, resulting in a blank screen.
So, flip the switch.
Higher-end thermostats feature safety switches that cut off power when damage is detected on your air conditioning or heating unit. One common cause is the evaporator coils freezing, resulting in excess condensation that drains from the AC system. The safety switch ensures no further damage to your unit pending when you can self-diagnose or inform a professional.
This safeguard protects your HVAC system from damage and unwanted access. An open access door can be easily overlooked, especially slightly ajar. But when you consider that dust and other debris can get in and cause serious damage, it starts to look like a more serious problem. The problem becomes exaggerated if you have curious children ready to fiddle with anything in sight.
For these reasons, some HAVC manufacturers created a system that blanks out your thermostat screen to call your attention when your access door is not satisfactorily closed.
Suppose you installed your HVAC system without experience installing home appliances. In that case, it is only a matter of time before your thermostat screen goes blank. The outcome would be the same if you left the installation in the hands of inexperienced technicians. As a result, it is crucial to have your system installed and maintained by professionals with a proven track record.
If all else fails, the thermostat will need to be repaired or replaced. An HVAC expert can inspect the thermostat and provide the best option.
