Our take on the Dual Run Capacitor Round CBB65 40/10uF MFD 370V AC 40/85/21 Aluminum Case for Air Conditioner Compressor Motor Heat Pump Condenser

This is a round CBB65 dual run capacitor with a 40 µF compressor section (HERM) and a 10 µF fan section (FAN) on a shared common terminal, rated 370V AC. The aluminum case measures about 4.9 inches tall by 2.2 inches across, and each of the three terminals takes four spade pins. It is a direct replacement part for a weak or bulging dual capacitor in a residential AC condenser, heat pump or compressor motor. Compared with single-section capacitors it saves wiring because one can serves both the compressor and the condenser fan. Buyers judge it on whether the microfarad ratings measure close to spec and whether it lasts past a few summers; the 370V rating suits most US residential units, while 440V-rated capacitors give more headroom on 240V systems.

Pros
  • One can covers both compressor (40 µF) and fan (10 µF)
  • ±5% tolerance on capacitance
  • TUV recognized
  • Aluminum case resists heat and corrosion
  • Standard 4-pin-per-terminal layout fits common quick-connect leads
Cons
  • 370V rating is below the 440V some 240V systems specify
  • Round 2.2-inch diameter will not fit every mounting bracket
  • No discharge resistor or bleed-down built in
  • Must be discharged and matched to the old label before fitting

What reviewers say

Owners of this type of CBB65 capacitor generally report it restores cooling after a swap and holds its microfarad value. Complaints center on short service life in hot condenser cabinets and on units arriving out of tolerance.

What people mention
  • Capacitance accuracyMixedSome buyers measure close to 40/10 µF; others find a section reading outside the ±5% tolerance.
  • Service lifeCriticisedSeveral owners report failure within one or two cooling seasons, especially in hot condenser cabinets.
  • Fit and sizeMixedThe round 2.2-inch case fits many mounts but not all, so buyers check the old capacitor's dimensions first.
  • Terminal layoutPraisedThe HERM, FAN and C labels and four pins per terminal make wiring straightforward for DIY replacement.
  • Build qualityMixedThe aluminum case feels solid, but some units arrive with a bulged top or leak.

About the Dual Run Capacitor Round CBB65 40/10uF MFD 370V AC 40/85/21 Aluminum Case for Air Conditioner Compressor Motor Heat Pump Condenser

Features:

This CBB65 dual run capacitor has characteristics of low loss, heat resistance, anti-overvoltage shock, excellent electrical performance and long service life; TUV recognized.

There are 3 terminals (HERM/ FAN/C) on the top of the dual run capacitor, 4 pins per terminal. "HERM" for the air compressor, "FAN" for the fan, "C" for the common line.

This run capacitor is applied to starting and working of a single-phase motor in a 50Hz/60Hz AC electric power system.

The CBB65 capacitor is widely used for air conditioners, air compressors, motors, refrigerators, heat pump condensers, HVAC, generators, illuminating lamps, fans, etc.

Note:

If the capacitor of your motor and air compressor is burnt out or weak, you need to replace it with a new one.

Questions and answers

Will this replace my old 40/10 µF capacitor?
Yes, if your old dual capacitor is rated 40 µF plus 10 µF at 370V AC or higher and fits the same round 2.2-inch footprint. Match the HERM, FAN and C wires to the same terminals on the new part.
Is 370V enough, or do I need 440V?
370V AC is the common rating for US residential condensers and heat pumps. If your old label says 440V, buy a 440V-rated capacitor instead; a higher voltage rating is safe, a lower one is not.
How do I know which terminal is which?
HERM is the compressor, FAN is the condenser fan motor and C is the common line from the contactor. The labels are stamped on the top next to the terminals.
Can I install it myself?
Only if you shut off power at the disconnect and discharge the old capacitor first, since it can hold a charge. If you are not comfortable working inside the unit, have an HVAC tech fit it.
What is in the box?
One CBB65 dual run capacitor. Spade connectors, mounting brackets and wiring are not included.
Does it work for heat pumps and refrigeration?
Yes, it suits single-phase 50/60 Hz motors in heat pumps, compressors, refrigerators and similar HVAC equipment, as long as the ratings match.
