Your thermostat serves as the \u201cbrain\u201d of your HVAC systems, enabling you to choose when your heating or cooling unit turns on and what temperature your home will be. Ideally, your thermostat will never interfere with the performance of your furnace. The components in your heater will function as they\u2019re supposed to regardless of what temperature you set your thermostat at, after all.<\/p>\n
However, problems with your thermostat can impact your ability to control <\/em>your furnace, and as such can be just as aggravating a problem as a malfunctioning heater. Keep reading to learn more about how a faulty thermostat can affect your entire heating system.<\/p>\n When your thermostat isn\u2019t working as it should, your heater won\u2019t receive the signals it is supposed to in order to turn on when it should and\/or turn off when it\u2019s supposed to. As a result, you\u2019re stuck with an uncomfortable home, and you\u2019ll also be wasting money on higher electric bills.<\/p>\n If your thermostat misreads the temperature, for instance, it may signal your heater to turn on during an already hot day\u2014turning your home into a sauna and wasting precious energy to do it. On the same token, the temperatures may drop but your thermostat will fail to recognize it and your heater won\u2019t turn on as early as it should, leaving you with no heat at all.<\/p>\n Another problem that a faulty thermostat may cause is a heater that cycles on and off rapidly. This process is called short cycling. <\/em>Unfortunately, most of your furnace\u2019s energy is spent on cycling on and off, so if it\u2019s doing it too much then your furnace will fail to work as efficiently as it should, and wear down faster.<\/p>\nYour Furnace Won\u2019t Turn On or Off<\/h3>\n
