5 Reasons Your Thermostat is not reaching Set Temperature

During cold winter days, we all want to get in a warm house and rest, but If the thermostat in your house doesn’t reach the set temperature; resting might not be very easy. When a thermostat does not function properly, it may mean that there is an issue with its heating system, or the thermostat itself. It could also be due to several other reasons.


Doing quick research to determine the problem before consulting HVAC repair professionals is the right thing to do. You get to find the problems and save some money as well. In this article, we would look at the possible reasons why your thermostat does not reach the set temperature and the possible solutions.

Why Your Thermostat Doesn’t Reach the Set Temperature

1. Size of Thermostat:
The size of your thermostat is the number one reason why this issue could happen. If the thermostat temperature is too small for a home or not designed to cover an area size, it might not reach the set temperature.

Solution
Get a thermostat
that suits the size of your home or apartment. If you are clueless about how to do this, get professional help and advice.

2. A Broken Thermostat:
Your thermostat could be broken, and show the set temperature on its screen, but not reach it.

Solution
If yours is a thermostat that comes with programmable features, it will turn itself off at inappropriate times. If not, use a thermometer to check the degree of air surrounding the thermostat to determine if what it shows on the screen is right or wrong.

3. A Dysfunctional Fan:
The fan of the thermostat and its dysfunctions is another reason. The fan and furnace relation is important when checking if the thermostat works well or not, due to the warm air it pumps.

Solution
You should switch off the fan after two minutes of switching off the furnace. If this is not done, the fan will keep pumping cold air, breaking the balance of your thermostat in the process.

4. Frozen Thermostat:
Another reason is the thermostat being frozen. These days, almost all thermostats are smart. And you may experience problems with the touch screen of your thermostat if there is a problem with the static electricity around it. The thermostat’s display may freeze and stop sending data updates that you need on the screen. When this happens, if the thermostat doesn’t reach the set temperature, you wouldn’t notice.

Solution
When this occurs, you should try rebooting the thermostat. Please turn it off for several seconds, wait, and then switch on to see what happens.

5. Loss of Power:
Your thermostat may lose its power. When this occurs, it may prevent the thermostat from reaching the set temperature. You would know that the thermostat has lost its power when the screen is dark or blank, when you cannot see the status on the screen, or when the condenser and furnace are not working.

Solution
Before calling for professional help, check if the thermostat system and furnace are getting power. If they are not, it may be time to repair them.
