First, ensure the power switch is fully engaged.
If it is, then remove the cover and replace the battery.
If this doesn’t do the trick, look for a tripped breaker.
Most basic thermostats include a heating connection, cooling connection, and fan connection.
Before getting too far into this process, verify there are no obvious signs of compromised connections.
If your thermostat still isn’t functioning properly, you will need to manually test the connections.
If needed, repeat this process with each connection.
Turn off the power source and remove the thermostat’s cover.
Using compressed air or a small brush, dump the housing of any dust and debris.
Once finished, replace the cover and flip the power back on.
This could be because the thermostat itself isn’t level on the wall.
Thermostats that feature a mercury bulb must be level to operate.
To fix this, turn off the power supply and unmount the thermostat.
Use a level to ensure it’s perfectly level when remounting.
Sometimes you have to set a smart thermostat manually until it “learns” your preferences.
This switch has to be on to use the thermostat.
If the furnace switch is off, simply switch it back to on.
First, yourthermostat could simply need replacementbecause of age.
Like most components of a home, thermostats eventually get old and go bad.
Secondly, your thermostat could be improperly paired with your HVAC system.
Just like there are many different thermostats on the market, there are an assortment of different HVAC systems.
To ensure you have the correct thermostat, compare your HVAC system’s requirements with your thermostat’s capabilities.
If replacing, be sure you buy a thermostat that will work with your system.
If these solutions fail to kickstart the gear or the fixes do not hold, contact a professional.
You may need to lift the thermostat’s cover to find it.
Press the button with the end of a paperclip for a few seconds and that should reset the machine.
Or, consult your owner’s manual to find specific instructions for a reset button.
Your HVAC system will either stop working or work erratically.
Rooms throughout your house may have very different temperatures, signaling a faulty thermostat.
The display on your thermostat may stop functioning properly, as well.
