Dual-run capacitors feature a run capacitor, and they feature a start capacitor. You can use a dual-run capacitor in place of separate run and start capacitors. Start capacitors provide the motor to which they are connected an initial jolt of electricity. The motor will then begin to spin. Run capacitors provide the motor with supplemental electricity when needed. Motors don''t always
Dual run capacitors are commonly used in HVAC (heating, ventilation, and air conditioning) units. Dual capacitors have three terminals, unlike regular run capacitors, which have only two. Electrically, they are the same as run capacitors that have two terminals. Using a dual run capacitor allows you to save space if you have a small mounting
Dual run capacitors are essential components in many air conditioning and HVAC systems. They serve a dual purpose by providing electrical boosts to both the compressor and the fan motor.

What Does a Dual Run Capacitor Do?
It is important to ensure that the Dual Run Capacitor selected matches the specifications of the HVAC system’s compressor and fan motors, power supply, and space available. An incorrect match of voltage, frequency, case style or terminal type may cause the HVAC system to malfunction or fail.
To spot a dual run capacitor that operates both the compressor and the fan motor, look for three terminals on the capacitor: one will be marked "common" or may be marked with a red dot to indicate that role.
The dual ratings in a single can provide two capacitors - one may be used as a fan capacitor and the other as a compressor or motor run capacitor. Three terminals allow one terminal to act as a common while the other two are connected to the individual capacitors. Trust the wiring diagram. Here is a typical SF type capacitor specification sheet:
Type SF dual rated oil filled motor run capacitors made with self-healing metallized polypropylene film are commonly used in air conditioning, motors and compressor applications. The dual ratings in a single can provide two capacitors - one may be used as a fan capacitor and the other as a compressor or motor run capacitor.
However, replacing both is a better option (especially if you have hired an HVAC technician) since capacitors are cheap but technicians are expensive, and it will be just a matter of time before the other capacitor fails as well. A good HVAC technician will even recommend replacing both single run capacitors with a dual run capacitor.
