Your furnace keeps your house comfortable during the frigid winter months, so it’s disconcerting when something is off. One routine complaint is a furnace that continually turns on and turns off over and over. This operating error is known as short cycling. It stresses equipment and might result in costly repairs or even early failure.
Short cycling can be the result of for varying reasons. Before you request furnace repair, research the possible causes and how to resolve the issue.
The HVAC filter attracts airborne dust, hair and other substances that could wreak havoc on furnace. If you don’t get a new filter regularly, it can become dirty and decrease the airflow. When this takes place, a safety mechanism switches off the furnace to avoid overheating. Inspect the filter, and if it’s dirty, replace it. Going forward, replace the filter every 30 to 90 days to keep your furnace from short cycling.
A dirty filter isn’t the only issue that can reduce airflow and overheat your furnace. Walk around your house and look for shut or crowded air vents. For recommended system balance and performance, keep all registers open, even in unoccupied rooms.
The furnace blower has blades that distribute air through the ductwork. If they are caked with dirt, the air won’t move correctly, causing overheating and short cycling. Regularly replacing the filter is the simplest method to avoid a dirty blower wheel. If the blades are already dirty, request furnace maintenance to have them cleaned.
Check your thermostat next. This is the brain of your HVAC system and instructs the furnace on what to do. Ensure the thermostat is set to heating mode and auto fan with the desired temperature showing on the screen. Try replacing the batteries. Also, check whether the thermostat is in bright sunlight or near a heat source that could affect the temperature reading. If you rely on a smart thermostat, go to the manufacturer’s site for troubleshooting tips.
The flame sensor turns off the gas valve when no burner flame going. The sensor can’t detect the flame if it’s coated in soot, so the gas switches off sooner and the furnace shuts off. Leave the work of repairing a dirty flame sensor to an Expert like Atmostemp Service Experts.
