Why is My Thermostat Blank?

a blank thermostat

A thermostat is an important device that allows you to set the temperature of your HVAC system. If it
stops working, you won’t be able to switch the heating or air conditioning on or off either. This makes it essential that your thermostat always stays in working condition. However, sometimes it can go blank.

So, what might be the cause of a blank thermostat? Let’s find out!

Top 4 Reasons Your Thermostat is Blank

Here are the 4 most common reasons why a thermostat goes blank:

1. Dead Batteries

In most cases, the batteries may be the culprit. While you may think you’re dealing with a broken
thermostat, chances are, the device only needs a fresh set of batteries. Simply replace them, and your
thermostat should work without any issues.

2. Breaker Trip

Check your breaker if you’ve replaced the batteries and the thermostat is still blank. In most homes,
thermostats are connected to the main electrical system. Consequently, they may cause the breaker to
trip.

If the breaker tripped, switch it back on, and the power to your thermostat will be restored.

3. Tripped Safety Switch

A transformer sends voltage that runs through your thermostat. But in the case of a blank thermostat, it might be possible that the transformer stops sending the voltage due to an underlying problem with the HVAC system.

Check your heating and air conditioning systems to see if the safety switch has tripped. In most cases,
the safety switch is tripped when excess moisture or an abnormally high temperature is detected. This is done to ensure your system does not sustain any irreparable damage.

In this case, it is best that you call in a professional and let them inspect your HVAC system and
thermostat. They can help find the root cause of the problem and make the necessary repairs to fix
them.

4. Broken Thermostat

Most thermostats have a life of approximately 10 years. However, this duration can vary. If nothing else seems to be wrong, chances are you have a broken thermostat.

In this case, your thermostat will need to be replaced entirely. But just to be sure, you should contact
your HVAC professional.
