Why Does Your Furnace Shut Off Before Reaching Temperature?

Why Does Your Furnace Shut Off Before Reaching Temperature?

When you discover your home’s temperature is uneven, check to see whether your heater is constantly going on and off. If the run-time appears to be shorter than usual, the heater may be deferred to ­short-cycling.

Short-cycling occurs when a heater does not finish its normal heating cycle and shuts off too soon. A furnace or heat pump’s whole heating cycle takes about 15 minutes or more. No matter how low you set the thermostat, if your heater continues turning off after only five minutes, it’s too short.

Short Cycling Causes

  • Blocked Air Filter
  • This is one of the most common causes of HVAC system failure. The furnace may switch off as a safety precaution if the filter is substantially blocked with dust and debris. All you have to do here is replace the dirty filter. Depending on how often you use the heater and the filter’s intensity, we recommend changing it every 1 to 3 months. If it’s been more than 3 months since you changed the heater, it is advisable to call a heating contractor in Los Angeles and get it changed.

  • The Thermostat that doesn’t Work
  • Your heater may continue turning on and off because your thermostat is giving false signals. It’s possible that the thermostat is sensing temperatures erroneously or that there’s a problem with the heater’s control board. Technicians can re-calibrate the thermostat or make other repairs to ensure that the heater is operating properly.

  • Flame Sensor that has been Corroded
  • This holds true for gas furnaces, the most prevalent type of heating equipment. When the gas valve is open, the flame sensor determines if the burners are on. If the sensor detects no flames, the gas will be turned off, preventing an accumulation of unburned gas in the combustion chamber. The flame sensor can’t detect fire when it’s covered in dirt or debris. It will continually close the gas valve, causing the furnace to shut down.

  • Heater with a Large Capacity
  • An improper installation is the most serious issue that will cause a furnace to continuously switch off. When a heater is too strong for a home, it heats the living spaces too quickly, causing the thermostat to turn off the heater too soon.

    In this instance, the only thing you can do is arrange a heating installation in Los Angeles for a new heating system to be installed, this time by a skilled specialist who will ensure that the heater is the correct size.

  • Overheating
  • Your furnace may overheat and shut down if temperature-monitoring components are defective. One of the most common causes of short cycling is frequent overheating. The majority of modern furnaces will have a temperature-controlling safety feature built-in.

    Short cycling can also be caused by a malfunctioning heat exchanger. In the worst-case situation, a damaged heat exchanger will leak heat into other furnace components. Be quick to call a heating contractor in Los Angeles and get the problem fixed.
