6 Reasons Why Your Furnace Keeps Shutting Off and How to Take Care of It
Your furnace keeps your family warm during the chilly winter months, so it’s disconcerting when something isn’t quite right. One frequent complaint is a furnace that continually kicks on and turns off again. This issue is called short cycling. It strains equipment and could result in costly repairs or even earlier than normal failure.
Short cycling can be the result of for a few reasons. Before you request furnace repair, read about the probable causes and how to fix the problem.
1. Clogged Air Filter
The HVAC filter traps airborne dust, hair and other substances that could cause problems for furnace. If you don’t change the filter often enough, it can eventually be filthy and decrease the airflow. When this takes place, a safety mechanism switches off the furnace to prevent overheating. Check 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. Obstructed Air Vents
A dirty filter isn’t the only thing that can lower airflow and overheat your furnace. Walk around your residence and look for unopened or blocked air vents. For adequate system balance and performance, keep all registers open, even in empty rooms.
3. Dirty Blower Wheel
The furnace blower uses blades that distribute air through the ductwork. If they are dirty, the air won’t travel correctly, creating overheating and short cycling. Regularly putting in a new the filter is the easiest approach to avoid 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 brain of your HVAC system and gives the furnace instructions 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 putting in new batteries. Also, check whether the thermostat is in bright sunlight or near a heat source that could influence the temperature reading. If you rely on a smart thermostat, visit the manufacturer’s site for troubleshooting tips.
5. Dirty Flame Sensor
The flame sensor switches off the gas valve when no burner flame going. The sensor can’t sense the flame if it’s covered in soot, so the gas switches off too soon and the furnace shuts down. Leave the work of cleaning a faulty flame sensor to a professional like Winnipeg Supply Service Experts.
6. Oversized Furnace
When it comes to HVAC equipment, oversized isn’t always better. A larger system adds warmth to your house too quickly, causing intolerable temperature fluctuations and short cycling. The only way to fix this situation is to do new furnace installation.
