How do I fix my short cycling compressor?
How To Stop and Prevent Short-Cycling
- Check your air filter. Believe it or not, a clogged air filter can cause a wide variety of air conditioning issues.
- Check your thermostat placement.
- Check your air conditioner’s refrigerant levels.
- Replace the low-pressure control switch.
- Check the compressor.
What causes an air compressor to short cycle?
Pressure or temperature control differential is too small: When the pressure controller’s low pressure differential is set too tight, it can cause the compressor to short cycle. When your temperature and pressure differential is too small you’ll take longer to achieve set point and use more energy use in the process.
What causes a compressor to short?
Compressor burnout is a very specific mode of failure that may be caused by high temperatures in the motor windings or discharge area of the compressor. High temperatures break down the motor winding insulation, which may cause a loss of electrical resistance and result in a short to the ground or even an open winding.
What is the reason for short cycling?
Frozen evaporator coils are a common cause of short cycling. Sometimes, air conditioners freeze up when they’re running while it’s too cold outside, usually at night. In other cases, freezing may be caused by a dirty filter or a mechanical problem.
Can a faulty thermostat cause short cycling?
Your thermostat could also cause the HVAC system to cycle on and off rapidly, a process known as short cycling. Your furnace or central air conditioner spends a good amount of energy simply turning on and off, which is why you want yours to run for at least 15 minutes at a time before shutting off.
How do I stop short cycling?
Will compressor run with bad capacitor?
The most common problem that bad capacitors can cause is “hard starting.” This is when the compressor of an AC has difficulty starting up, stutters trying to turn on, and then shuts off a short while later. Before a capacitor fails, it may start begin to make a clicking noise.

How to Tell if Your Furnace is Short-Cycling & What to Do
- It’s overheating.
- Having a bad flame sensor.
- Your furnace filter is dirty.
- Blocked heat grates.
- Blocked exhaust vent.
- Your thermostat mounted in the wrong location.
- The furnace that is too big for your home.
