Your furnace keeps your house warm during the frigid winter months, so it’s annoying when something is wrong. One frequent issue is a furnace that endlessly turns on and turns off over and over. This issue is called short cycling. It stresses your furnace and might cause costly repairs or even early failure.
Short cycling can be the result of for a few reasons. Before you book furnace repair, research the possible causes and how to resolve the issue.
The HVAC filter catches airborne dust, hair and other substances that could wreak havoc on furnace. If you don’t change the filter frequently, it can eventually be filthy and decrease the airflow. When this takes place, a safety device turns off the furnace to stop 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 residence and look for unopened or blocked air vents. For recommended system balance and performance, keep all registers open, even in unoccupied rooms.
The furnace blower has blades that push air through the ductwork. If they are covered in dirt, the air won’t move correctly, causing overheating and short cycling. Routinely replacing the filter is the simplest approach to avoid a dirty blower wheel. If the blades are already dirty, book furnace maintenance to have them cleaned.
Check your thermostat next. This is the core of your HVAC system and tells the furnace what to do. Ensure the thermostat is on heating mode and auto fan with the desired temperature showing on the screen. Try putting in new batteries. Also, check whether the thermostat is in bright sunlight or near a heat source that could affect the temperature reading. If you have 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 turns off sooner and the furnace shuts off. Leave the work of fixing a dirty flame sensor to a pro like Golden Seal Service Experts.
When it involves heating and cooling equipment, larger isn’t always best. An oversized system warms up your home too fast, causing intolerable temperature swings and short cycling. The only way to resolve this issue is to request new furnace installation.
