Your furnace keeps your you cozy during the chilly winter months, so it’s frustrating when something is off. One routine complaint is a furnace that continuously switches on and shuts back off again. This operating error is known as short cycling. It overworks your furnace and might lead to expensive repairs or even earlier than normal failure.
Short cycling can be the result of for several reasons. Before you schedule furnace repair, research the possible causes and how to fix the situation.
1. Dirty Air Filter
The HVAC filter traps airborne dust, hair and other debris that could wreak havoc on furnace. If you don’t get a new filter frequently, it can eventually be filthy and decrease the airflow. When this takes place, a safety mechanism shuts off the furnace to prevent getting too warm. Inspect the filter, and if it’s dirty, install a new one. Going forward, replace the filter every 30 to 90 days to keep your furnace from short cycling.
2. Obstructed Air Vents
A dirty filter isn’t the only trouble that can restrict airflow and overheat your furnace. Walk around your residence and be on the lookout for for unopened or blocked air vents. For proper system balance and performance, keep all registers open, even in unoccupied rooms.
3. Dirty Blower Wheel
The furnace blower consists of blades that distribute air through the ductwork. If they are covered in dirt, the air won’t travel properly, leading to overheating and short cycling. Regularly putting in a new the filter is the simplest way to prevent a dirty blower wheel. If the blades are already dirty, book furnace maintenance to have them cleaned.
4. Faulty Thermostat
Check your thermostat next. This is the core of your HVAC system and instructs the furnace on what to do. Double-check the thermostat is set to heating mode and auto fan with the desired temperature shown on the screen. Try replacing the batteries. Also, check whether the thermostat is in bright sunlight or near a heat source that could impact the temperature reading. If you rely on a smart thermostat, go to the manufacturer’s site for troubleshooting tips.
5. Soot-Covered Flame Sensor
The flame sensor is responsible for turning off the gas valve when no burner flame on. The sensor can’t find the flame if it’s covered in soot, so the gas shuts off sooner and the furnace shuts down. Leave the job of cleaning a dirty flame sensor to an Expert like Coastal Service Experts.
6. Oversized Furnace
When it involves home comfort equipment, bigger isn’t always better. A larger system warms up your residence too fast, causing intolerable temperature swings and short cycling. The only way to take care of this issue is to request new furnace installation.
