A properly functioning furnace should cycle only 3-8 times each hour, depending on the state of your furnace system, the outside temperature, and other factors. You might have a furnace issue if your furnace cycles too frequently or runs for a few minutes before turning off. Your energy costs can be higher than they need to be, if your heating and cooling system regularly cycles on and off.
What Does A Furnace's Short Cycling Mean?
- Unclean Air Filter
A dirty air filter most frequently causes short cycling. The proper airflow to the heat exchanger won’t be possible if your air filter is clogged with dirt. It may lead to the furnace overheating, in which case the high-limit switch must intervene by turning the furnace off.
The cycle will continue after it cools and restarts. Short cycling of this kind can be easily avoided by regularly replacing the air filter in your furnace. The furnace needs to be cleaned or replaced every month to ensure it operates at its best.
- Issues Of The Parts
Your heat exchangers won’t be warming air if your blower motor is out, and the furnace may shut off. The mechanism turns the furnace off if the air temperature rises too high and may be broken, causing an early shutdown of the furnace. Your vent may be obstructed, preventing heated gasses from leaving the system correctly.
You can have a problem with your furnace if the vent isn’t functioning correctly or the ignition mechanism isn’t producing a flame in 4 seconds. A faulty ignitor or a dirty or damaged flame sensor (thermocouple) could be to blame. If you think this is the issue, have an expert for furnace repair in Twentynine Palms inspect the problem.
