Furnace short-cycling on and off — Los Angeles, California
A furnace that starts, runs for only a few minutes, shuts off, and restarts repeatedly is short-cycling. This wastes energy, strains the blower motor and heat exchanger, and leaves the house underheated. Common causes are a dirty air filter restricting airflow, an overheating limit switch tripping, a malfunctioning flame sensor, a thermostat placed near a heat source, or an oversized unit. An HVAC technician can diagnose the trigger, clean or replace the flame sensor, check the heat exchanger, and ensure proper airflow.
