What makes AC compressor kick on and off?

Short cycling, when the compressor constantly shuts on and off, is one of the most common air conditioning problems. Several conditions cause short cycling, including a faulty or obstructed thermostat, leaking refrigerant, icy coils or an HVAC system that is too big for the building in which it is installed.

Why does my AC keep turning off after a few seconds?

Got a central air conditioner that turns on and off every few seconds or minutes? This is called “short cycling” (because normally the AC has a regular on and off “cycle” that varies with the outside temperature.) Short cycling wears out the outside unit’s compressor.

Why does my AC compressor keep turning off?

If your AC is low on refrigerant (which means there’s a leak somewhere), then the resulting pressure change can trigger a safety switch that shuts down an important part called the compressor. If your compressor shuts down, your AC will stop cooling your home’s air.

What causes AC compressor to short cycle?

As we said above, short-cycling is often the symptom of a problem—this problem could be from any of the following circumstances: A clogged air filter. An oversized or undersized air conditioner. Low refrigerant charge due to leaks.

Can a bad thermostat cause short cycling?

A broken or poorly placed thermostat can cause short cycling. A thermostat positioned near a heat source or in direct sunlight can warm too quickly, signaling your furnace to shut off before the entire home is adequately warmed. This sometimes causes short cycling, depending on your temperature setting.
