FAQs about Dual Current Capacitor Repair
What is a dual run capacitor?
One sends the initial jolt of electricity to start the unit while the other keeps the unit running. Newer AC units and heat pumps use a dual run capacitor or dual capacitor. This capacitor handles both the start and run functions. It essentially contains two capacitors in one canister. HVAC capacitors are measured in voltage and microfarads (MFD).
Can a dual run capacitor be replaced?
When replacing an old capacitor, the capacitance ratings on the new capacitor must EXACTLY match the ones from the old capacitor. For example, if your old capacitor was rated for 45/5 uF, then the new capacitor must have the same exact 45/5 uF rating. A dual-run capacitor also has a voltage rating. The voltage rating is either 370 VAC or 440 VAC.
What happens if a dual run capacitor goes bad?
A dual run capacitor helps your AC's compressor and condenser fan motor turn on. If your dual run capacitor goes bad, then one or both of these components won't turn on. A dual run capacitor is actually two capacitors combined into a single package – one capacitor is for your compressor, and the other is for your condenser fan motor.
What is AC dual capacitor wiring?
AC Dual Capacitor Wiring: A dual capacitor combines both the start and run capacitor in one unit. The wiring is more complex but offers the benefit of a single component handling both tasks. Typically, the three terminals on a dual capacitor connect to the compressor, fan motor, and common wiring, each serving a specific function.
How do you test a dual run capacitor?
To test a dual run capacitor, you need to disconnect it from your AC unit, discharge the capacitor, and then use a multimeter to test it. Switch your multimeter to its capacitance testing setting and put the probes between the “COMMON” and “FAN” terminals to test the capacitance of the condenser fan side of the capacitor, as shown below.
Do dual run capacitors have a voltage rating?
A dual-run capacitor also has a voltage rating. The voltage rating is either 370 VAC or 440 VAC. The voltage rating on your new capacitor needs to meet or exceed the voltage of the capacitor that you're replacing. For example, if your old capacitor is 370 VAC, then you can use either a 370 VAC or a 440 VAC capacitor to replace it.

Causes of capacitor casing warping
The classic capacitor failure mechanism is dielectric breakdown. The dielectric in the capacitor is subjected to the full potential to which the device is charged and, due to small capacitor physical sizes, high electrical stresses are common. Dielectric breakdowns may develop after many hours of satisfactory operation. Open capacitors usually occur as a result of overstress in an application. For instance, operation of DC rated capacitors at high AC current levels can cause a localized heating at the end terminations. The localized heating is.
