Your furnace keeps your you warm during the frigid winter months, so it’s annoying when something is off. One common situation is a furnace that endlessly switches on and shuts back off over and over. This operating error is known as short cycling. It strains your furnace and could lead to pricey repairs or even premature replacement.
Short cycling can be the result of for a few reasons. Before you schedule furnace repair, read about the likely causes and how to resolve the situation.
1. Filthy Air Filter
The HVAC filter attracts airborne dust, hair and other debris that could wreak havoc on furnace. If you don’t get a new filter frequently, it can get filthy and block the airflow. When this occurs, a safety feature shuts off the furnace to stop overheating. Pull Out the filter, and if it’s dirty, get a new one. From now on, get a new filter every 30 to 90 days to keep 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 home and check for shut or blocked air vents. For recommended system balance and performance, keep all registers open, even in empty rooms.
3. Dirty Blower Wheel
The furnace blower consists of blades that move air through the ductwork. If they are dirty, the air won’t travel right, causing overheating and short cycling. Regularly putting in a new the filter is the simplest way to avoid a dirty blower wheel. If the blades are already dirty, schedule furnace maintenance to have them cleaned.
4. Faulty Thermostat
Inspect 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 showing on the screen. Try putting in new batteries. Also, check whether the thermostat is in direct sunlight or near a heat source that could influence the temperature reading. If you use a smart thermostat, check the manufacturer’s site for troubleshooting tips.
5. Sooty Flame Sensor
The flame sensor switches off the gas valve when no burner flame on. The sensor can’t detect the flame if it’s sooty, so the gas turns off too soon and the furnace shuts down. Leave the work of repairing a faulty flame sensor to a pro like Roland J. Down Service Experts .
6. Oversized Furnace
When it involves heating and cooling equipment, oversized isn’t always better. A larger system warms up your residence too fast, creating unpleasant temperature changes and short cycling. The only way to fix this issue is to schedule new furnace installation.
