Does Your Furnace Cycle Off and On Too Frequently?

Throughout winter, you rely on your furnace to keep your home warm in Bryson City, NC. If you notice your furnace short cycling or turning on and off too much, you likely have a problem that requires professional heating services. Below are some common causes of short cycling and what’s necessary to fix the problem.

Clogged Air Filter

Clogged air filters cause airflow restriction. When air can’t cycle through the system unobstructed, this causes the furnace to turn on and off more frequently. Fortunately, you can quickly solve this issue by replacing your furnace’s air filter.

Dirty Flame Sensor

If you have a natural gas or propane-powered furnace, it has a flame sensor. This sensor is responsible for turning on the flame that produces the gas. Sometimes, cleaning the sensor is enough to fix the problem. However, in the case of a malfunctioning sensor, you need to replace it to prevent the furnace from turning off prematurely. Always contact a qualified service technician to clean or repair the sensor.

Blower Motor Issues

Short cycling can be one of the first signs your blower motor is failing. Reasons for a failing blower motor include bad wiring, an unstable ground connection, or a bad speed control module. Blower motor issues affect airflow and performance, which is why you don’t want this issue to persist. Contact a qualified service technician for an inspection and get to the bottom of what’s causing the short cycling.

Other reasons your furnace might turn on and off frequently include:

• Thermostat issues
• Dirty ductwork
• Leaky ductwork
