When it comes to keeping a thermostat in good working order, there are a few key points to consider. To begin with, the thermostat should be placed in an area where natural air currents can be detected, such as hot air rising and cold air descending. If the thermostat is blocked by furniture or other objects, it will not be able to accurately measure the temperature. Furthermore, the thermostat must be connected to several essential electrical connections in order to function properly.
These connections include a heating connection, a cooling connection, and a fan connection. If any of these connections are loose, corroded, or otherwise damaged, the thermostat will not be able to communicate with the air conditioning system.
