If your furnace is constantly switching on and off in short bursts instead of running full heating cycles, it’s likely experiencing short cycling. This issue not only leads to uneven heating but can also drive up energy costs and put unnecessary strain on your system. Homeowners in Bensenville, IL, should understand why short cycling happens and what steps can be taken to fix it. Let’s break it down. Here are some common reasons your furnace is short cycling.
1. Overheating Due to Restricted Airflow
When airflow is blocked—often due to dirty filters, closed vents, or clogged ductwork—the furnace can overheat. As a safety measure, the system automatically shuts down to prevent damage.
2. Thermostat Issues
A faulty or poorly placed thermostat can cause incorrect temperature readings, making the furnace turn off too soon. If your thermostat is near a heat source (like direct sunlight or an appliance), it may be tricking your system into thinking the house is warmer than it really is.
3. An Oversized Furnace
Bigger isn’t always better. If your furnace is too large for your home, it heats up too quickly and shuts off before properly distributing warm air. This results in inconsistent temperatures and wasted energy.
4. A Dirty or Malfunctioning Flame Sensor
The flame sensor’s job is to ensure the burner is operating safely. If it gets dirty or malfunctions, the furnace may shut off as a precaution—even when there isn’t a real issue.
5. A Blocked Exhaust Flue
Your furnace needs a clear path to vent out gases. If the exhaust flue is blocked—whether by debris, ice, or even small animals—the system will shut down to prevent dangerous gas buildup.
