Your thermostat controls your heater. On its own, your furnace or heat pump doesn’t detect the temperature in the room. If it did, your house would always have a weird temperature because the devices are away from the center of your home. If you look at where your thermostat is, you’ll see how it’s mostly central to the rest of your home.
That’s because it needs to detect the most common temperature in the home so it knows whether or not it needs to send a signal to the heater or not. It simply sends an on or off signal, the heater responds, then waits for further instruction. So how do you know if you need heater repair or if it’s the thermostat? Let’s help you find out.
