Your furnace keeps your house comfortable during the frigid winter months, so it’s annoying when something isn’t quite right. One frequent situation is a furnace that continually kicks on and turns off all the time. This operating error is called short cycling. It stresses your furnace and might result in expensive repairs or even earlier than normal breakdowns.
Short cycling can be the result of for varying reasons. Before you request furnace repair, review the potential causes and how to take care of the issue.
1. Dirty Air Filter
The HVAC filter catches airborne dust, hair and other debris that could damage the furnace. If you don’t get a new filter regularly, it can eventually be dirty and decrease the airflow. When this takes place, a safety mechanism switches off the furnace to stop getting too hot. Pull Out the filter, and if it’s dirty, replace it. From here on out, install a new filter every 30 to 90 days to prevent your furnace from short cycling.
2. Blocked Air Vents
A dirty filter isn’t the only trouble that can lower airflow and overheat your furnace. Walk around your house and check for unopened or crowded air vents. For adequate system balance and performance, keep all registers open, even in empty rooms.
3. Dirty Blower Wheel
The furnace blower has blades that distribute air through the ductwork. If they are caked with dirt, the air won’t travel right, leading to overheating and short cycling. Routinely changing the filter is the simplest way to stop a dirty blower wheel. If the blades are already dirty, request furnace maintenance to have them cleaned.
4. Faulty Thermostat
Check your thermostat next. This is the cortex 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 displayed on the screen. Try replacing the batteries. Also, check whether the thermostat is in direct 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.
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 coated in soot, so the gas switches off sooner and the furnace turns off. Leave the work of repairing a faulty flame sensor to an Expert like Knochelmann Service Experts.
6. Oversized Furnace
When it comes to HVAC equipment, bigger isn’t always right. A larger system heats up your residence too rapidly, causing unpleasant temperature swings and short cycling. The only way to resolve this problem is to request new furnace installation.
