How To Check If A Thermostat Is Working

A thermostat is a device that detects temperature changes to keep the temperature of an enclosed area constant. If you think your furnace is not working properly, it’s essential to check the thermostat first. A furnace that doesn’t turn on is usually due to an issue with the thermostat. If you are facing these issues, our team of qualified professionals provide the most reliable furnace repair in Los Angeles, CA.

Here’s how to test if your thermostat is working:

  • Power supply to the thermostat:
    When your thermostat’s screen goes blank, this is a significant sign that something is wrong. It should typically display the room temperature and information about your programmed schedule. If the screen is dark, the batteries are likely dead, or the thermostat is experiencing a major malfunction.
  • Responsive thermostat:
    The thermostat should respond almost instantly when you change the temperature. A quiet clicking sound will most likely be heard, followed by air moving through the ductwork. If you don’t hear or feel anything after a minute or two, your thermostat may not be working and needs a replacement.
  • Thermostat neglecting programmed settings:
    A programmable thermostat is intended to remember your settings and schedule over time. Your settings should not be “forgotten” until you decide to change them. So, if the thermostat isn’t following your schedule, it may be worn out and need to be replaced or repaired.
  • The thermostat does not correspond to room temperature:
    A properly functioning thermostat should display an accurate temperature of what it feels like inside your home. However, your thermostat isn’t measuring the temperature if the room feels much hotter or colder than the display temperature.
  • Short cycling:
    Short cycling is when your HVAC system turns off before completing a full heating or cooling cycle. Short cycling consumes a lot of energy and wears out HVAC components much faster than a system that can complete full cycles. If you are experiencing this, your thermostat is not working properly.
  • Air conditioner or furnace will not turn on:
    A faulty thermostat can prevent your heater or air conditioner from turning on. This usually indicates that the wiring has failed. Electrical wires typically transmit messages from the thermostat to the HVAC unit, such as when to turn it on and what temperature to set your house. If the wires malfunction, your thermostat will be disconnected from the AC and furnace, rendering them unable to function.
  • Inconsistent heating or cooling:
    If the thermostat is malfunctioning, it might not be able to accurately control the temperature in your home. This can lead to inconsistent heating or cooling, with some areas of the home being too hot or too cold while others are comfortable. If you are experiencing inconsistent heating or cooling, it is important to diagnose and fix the problem as soon as possible to ensure that your home is comfortable and energy efficient.
