Rheem Rheem R96V 96% AFUE Two-Stage Variable Speed Upflow Gas Furnace SHORT CYCLE Error Fix: Furnace Short Cycling — Shuts Off Too Soon

The furnace starts heating, runs for a few minutes, then shuts off before the house reaches the setpoint. This cycle repeats. The most common cause is a dirty air filter that restricts airflow across the heat exchanger, causing the high-limit switch to trip from overheating. Replace the air filter immediately. Other causes: undersized ductwork or too many closed registers (restricting return or supply air), a failed blower motor run capacitor (blower runs at reduced speed, insufficient airflow), an oversized furnace for the duct system, or a faulty thermostat sending intermittent signals. If the furnace consistently runs for exactly the same short period before shutting off, the high-limit switch is likely tripping — check airflow first.
