Why is the thermostat not reaching set temperature and what is the solution?
Size of the Thermostat
It is really important to check whether the size of the thermostat is appropriate for your home. Small thermostats might not function for bigger homes. It will be difficult for the device to cover the entire area and you will notice the thermostat not reaching set temperature. Also, the HVAC system might not be able to operate in your entire house.

Wrong location of the thermostat
If you face any issue with your thermostat not reaching a set temperature, it could be a problem with the location of the thermostat. For example, if the device is placed near the kitchen where the temperature is higher due to cooking and heating, then the display might read higher than usual. Installing the device at an ideal location, away from all heating and cooling, will help the thermostat to function up to the mark.
With the location, there are some practical things to be taken into consideration. Appliances like a hairdryer should not be kept or used near the device.
Dirt in your device will prevent the thermostat not reaching set temperature. You will have a hard time reading the correct temperature. In such a case, remove the cover and brush the dust away. You can also use a compressed air spray while doing so. However, cleaning is easy but the thermostat is an extensively sensitive device. Therefore it is recommended to hire a professional for gentle cleaning.
Cleaning should be done regularly, to prevent the dysfunction of the thermostat. Use a soft tip brush to remove the dust. While doing this make sure you don’t mess with the wires or any other delicate components inside the device. Do not use a vacuum cleaner to clean the thermostat.
The thermostat will face issues if the wires are loose. It could cause problems with the display or thermostat not reaching the set temperature. It is important to make sure that the wiring is securely connected. With loose wiring, corrosion might also be one of the causes.
Avoid cleaning with the brush as much as possible because this might loosen the wirings. A cotton swab will be a better replacement for harder-to-reach places. The swab can also be used for clearing corrosion.
Thermostat is unlevel
Another reason for the thermostat not reaching set temperature is that the device is unleveled. It can show incorrect reading if it is not in level with the wall. If not mounted properly, the pin connection between the device and the back slab will be disturbed which will lead to dysfunction of the thermostat. You need to fix and level the device properly on the wall for the device to function correctly.
The backplate should be squared to the wall with the help of screws. Try to replace the faceplate and check if the device works fine.
Other reasons to contemplate
Apart from the above-mentioned reasons, you should consider a few other things when the thermostat does not reach the set temperature.
- Check if batteries are dying
- Consider how old the thermostat is
- Broken or damaged sensors
- The air conditioner or furnace might be spoilt
- The fan dysfunctions and pumps due to warm air
- Uneven mercury switch
