As an expert in HVAC systems, I've encountered various issues that homeowners face with their heating systems, and short cycling is one of the more common problems. When a furnace short cycles, it means the furnace is turning on and off more frequently than it should, which is not only inefficient but can also be a sign of a more serious issue.
Short cycling can be caused by several factors, and one of the primary reasons is overheating issues. The heat exchanger, a critical component of a gas furnace, is responsible for transferring heat to your home's air. When this part overheats, it can lead to the furnace shutting down as a protective measure to prevent further damage. Overheating can be a result of several factors, including:
1. Faulty Gas Valve: If the gas valve is not functioning correctly, it can cause too much gas to flow into the furnace, leading to overheating.
2. Improper Airflow: Inadequate airflow can prevent the heat exchanger from transferring heat efficiently. This can cause heat to accumulate within the heat exchanger, eventually causing it to overheat.
3. Dirty Air Filter: A clogged air filter can restrict airflow, leading to the same problem of insufficient heat transfer and potential overheating.
4. Duct Issues: Leaky or undersized ducts can restrict the flow of heated air, causing the furnace to work harder and potentially overheat.
5. Thermostat Problems: An incorrectly set or malfunctioning thermostat can also lead to short cycling by not accurately reflecting the room's temperature.
When a furnace short cycles due to overheating, it's crucial to address the underlying cause to prevent damage to the heat exchanger or other components. Regular maintenance, such as cleaning or replacing the air filter and checking for duct leaks, can help prevent short cycling. Additionally, having a professional inspect and service your furnace annually can identify and correct potential issues before they lead to more significant problems.
Now, let's move on to the translation.

#1: Overheating issues. When your gas furnace's heat exchanger--the part that heats your home's air--overheats, your furnace will shut down to protect it from further damage. ... Low airflow means the heat exchanger can't transfer enough heat, and when that heat builds up, it could cause your furnace to short cycle.Oct 11, 2017
