What a Blank Thermostat Screen Means

When your HVAC’s thermostat is in good working condition, you can easily adjust the indoor temperature in your Las Vegas, Nevada, home. However, your thermostat will eventually show signs of wear and may begin to malfunction over time. One common problem is nothing showing on the device. A blank thermostat display can result from several issues, many of which require only a simple fix. Find out some of the reasons your thermostat’s screen could go blank and what you can do.

Batteries Are Dead

While some HVAC thermostats run on the main power supply in homes, others use batteries that you will need to replace approximately once a year. If your thermostat runs on batteries and has a blank display, you may be able to get it working again by simply replacing old batteries.

Tripped Circuit Breaker

Your HVAC thermostat may be on the same circuit breaker as other devices that use a lot of power. If the breaker trips, it may cut off power to the thermostat, resulting in a blank screen. All you need to do to fix the problem is flip the circuit breaker switch on again.

Safety Switch Was Activated

Some HVAC systems will automatically activate a safety switch when they detect problems, in turn, shutting off the thermostat. During the warmer months, this can happen when the condensate pan overflows. Regardless of what problem triggers the safety switch, you should contact our service specialists for an inspection as soon as possible.

Your Thermostat Is Too Old

Your thermostat can last a long time. However, how well you use and care for the device are important factors. On average, a thermostat can work well for up to 15 years before you start to encounter problems. If you think age is a factor, our service specialists will help you to determine if you need a replacement.

If your thermostat is showing a blank screen, you won’t be able to make adjustments to the device or your system won’t work at all. Give us a call for repairs so that we can restore comfort as quickly as possible. If you need help with any HVAC thermostat problem, contact Johnny On The Spot at(725) 977-9461.
