Our take on the BOJACK 30+3 uF ±6% 30/3 MFD 370/440 VAC CBB65B Dual Run Start Round Capacitor for Condenser Straight Cool or Heat Pump Air Conditioner AC Motor and Fan Starting

This is a dual run capacitor for air conditioner condenser units and heat pumps: 30 uF for the compressor and 3 uF for the fan, in one round CBB65B can. It is rated 370/440 VAC with ±6% tolerance, so it covers both common residential voltage ratings. It suits a DIY repair of a unit that hums, starts hard or won't spin the fan, when the old capacitor's label matches these values. Against single-value capacitors, one dual can replaces two parts and saves wiring space; the trade-off is that both sections must match your unit's ratings exactly.

Pros
  • Two capacitances in one round can: 30 uF compressor, 3 uF fan
  • 370/440 VAC rating covers both common residential ratings
  • ±6% tolerance is typical for run capacitors
  • CBB65B round metal case fits standard capacitor straps and brackets
  • Simple two-terminal-plus-common wiring layout
Cons
  • Must match the old capacitor's uF values exactly; wrong values strain the motor
  • No discharge resistor or bleed-down built in, so it needs manual discharging before handling
  • Round can only fits mounts sized for its diameter
  • Brand and date markings are minimal, so verifying specs falls on the buyer

Questions and answers

Will this replace my old 30/3 capacitor?
Only if your old capacitor is labeled 30+3 uF (or 30/3 MFD) and 370 or 440 VAC. Match both numbers; a different fan value, such as 30+5, needs a different part.
What do the two numbers mean?
30 uF is the compressor section and 3 uF is the fan section. Each connects to its own terminal plus the common terminal.
Does 370/440 VAC mean it works on either voltage?
Yes. The 440 VAC rating covers 370 VAC systems, so it works on both common residential ratings.
Can I use it on a heat pump?
Yes, if the heat pump's condenser uses a 30+3 uF dual run capacitor at 370/440 VAC. Check the label on the old part first.
Do I need to discharge it before removing it?
Yes. Capacitors hold a charge after power is off. Shut off power at the breaker and discharge the terminals with an insulated resistor before touching it.
What is in the box?
The capacitor itself. Wiring and mounting hardware are not included, so reuse the existing strap and wires.
