Check to see if the thermostat is turned on

If your thermostat isn’t working, the first thing you should do is ensure that the unit’s turned on. It seems like a no-brainer, but sometimes people forget to turn their thermostats on, or they accidentally turn them off. 

If the thermostat is turned off, simply turn it on and set it to your desired temperature. If the thermostat is turned on but the temperature isn’t changing, there could be an issue with the unit’s power supply. 

If the power supply appears to be fine, then there may be an issue with the thermostat itself. In this case, you’ll need to call a professional for help.

Make sure the batteries are not dead

If the unit’s batteries are dead, you can try replacing them and see if that solves the problem. If your thermostat isn’t working after changing the batteries, you may need to reset it. 

To do this, turn off the power to the unit at the breaker box and then remove the faceplate of the thermostat. Once you have access to the wiring, locate the “R” terminal and disconnect it from the “RC” or “RH” terminal. After a minute or so, reconnect the wires and turn the power back on. This should reset the thermostat and cause it to start working again. 

See if there is a power outage in your area

check to see if there is a power outage in your area. If there is no power, then your thermostat will not be able to function. If this is the case, you’ll need to wait until power is restored before your thermostat will work again. 

However, if your thermostat still isn’t working, then you may need to replace the unit. Thermostats don’t typically last forever, so it’s not uncommon for them to need to be replaced every few years.

Call a professional to help you fix the problem

There are a lot of different parts to a thermostat and trying to fix it yourself can be dangerous. 

A professional will be able to quickly diagnose the problem and get your thermostat up and running again. In the meantime, you can try to keep your home at a comfortable temperature by opening or closing windows and using fans. You should also avoid using any appliances that generate heat, as this could make the problem worse. 

By following these simple steps, you can minimize the discomfort caused by a broken thermostat and make sure that your home stays safe and comfortable.
