  • The best first step to take is to check your furnace’s air filter. If you find that it’s dirty, this means that air isn’t being able to properly move throughout the furnace itself. As a result, the temperature inside the furnace will increase while the limit switch proceeds to shut down all heating cycles in the event that the unit ends up becoming too hot. Air filters should always be replaced, on average, monthly, with the dirty ones being properly disposed of. From there, your furnace should restart once it has had time to cool down.
  • It’s also a good idea to check the fan setting on your thermostat. If the blower fan of your furnace is set to run on a continuous basis, this means that it will still run even when the system isn’t doing anything to produce heat. This means that cold air could be blowing from your furnace due to not double-checking the current settings. Take the time to look over your thermostat’s fan setting and make sure it’s set to auto instead of on. The auto setting will indicate that your furnace should run the fan only during a heating cycle and not push any amount of cold air through your vents in between.
