When your heating stops working, you are probably tempted to go straight to the heating unit and see what’s wrong, or call a professional to do it for you. No one can blame you for these actions. After all, if the heat stops working, it’s reasonable to assume that the heater is the cause. Believe it or not, however, this isn’t always the case. Read on to find out how the thermostat can affect your heating.
The thermostat is like the central nervous system of your heating system. It is responsible for everything your heater does, from when it turns on to when it turns off and everything in-between. Modern thermostats are primarily constructed of a sensor, control circuit, and user interface.
Once the desired temperature is set, the thermostat waits until the sensor registers a rise or drop from that temperature. Once the sensor registers a temperature change, the control circuit orders the heating system to start up. Once the temperature rises back to where it should be, the thermostat turns the heating system off. Incidentally, this is why it doesn’t warm the house faster if you turn the thermostat up higher. The temperature of the air the heating system produces is always the same. A higher thermostat temperature will just cause the system to work longer before turning off.
When you call an HVAC technician to your home to find out what’s wrong with your heating system, he or she will almost always check the thermostat first. That’s because, as mentioned previously, the thermostat is indispensable to the heating system’s operation. If the thermostat’s sensor is malfunctioning, the heater might never turn on. If the control circuit is broken, the heater might never turn off and vice versa. Even if the heating system itself is in absolutely perfect condition, a broken thermostat can prevent it from working. So, the next time your heater is having issues, don’t automatically assume there’s something wrong with it. Check the thermostat first, then call a professional.
