A CBB61 capacitor helps a ceiling fan’s motor start and run smoothly. It creates a phase shift between motor windings so the motor can develop starting torque and maintain speed. Many CBB61 capacitors contain single or multiple microfarad (µF) values, and the fan’s control (pull chain, wall switch, or remote) selects different values to set low, medium, or high speeds.

• Supports smoother startup on AC fan motors.
• Provides different µF values to adjust fan speed.
• Works with the fan’s existing speed control system.

When a capacitor weakens, you might notice humming, sluggish speeds, or the fan needing a gentle push to get going. Matching the correct CBB61 ratings can help restore expected performance.

Start by reading the printing on your old capacitor and match those details closely.

1. Microfarad (µF) value(s): Match each value exactly (e.g., 4.5µF+5µF+6µF). For single-value units, match the single µF.
2. Voltage rating: Choose the same or higher rating shown on your original. Using a lower rating isn’t recommended.
3. Wire count and configuration: Match 2-, 3-, 4-, or 5-wire designs and follow the wiring diagram on the label.
4. Physical size/case style: Ensure the CBB61 case fits inside the fan housing and bracket.

Walmart offers a range of CBB61 ceiling fan capacitors with different µF and wire options. If your wiring or labels don’t match, consider guidance from a qualified electrician for safe installation.

Several clues can point to a weak or failed CBB61 capacitor:

• Fan won’t start unless you give the blades a push.
• Only some speeds work, or speeds feel slower than normal.
• Noticeable humming or new buzzing sounds from the motor.
• Motor feels unusually warm during use.
• Visible damage: swelling, cracks, or a burnt odor from the capacitor’s case.

To confirm, you can remove power, disconnect the capacitor, and test it with a multimeter that measures capacitance. Compare readings to the µF value(s) printed on the label; if they’re significantly off, replacement may help. Always switch off power at the breaker, and contact a licensed electrician if you’re unsure.

CBB61 capacitors used in ceiling fans are non-polarized AC capacitors, so there’s no positive or negative side. Orientation in the mounting bracket doesn’t matter; what matters is connecting the correct wires to the correct circuits per your fan’s design.

• Follow the diagram printed on the capacitor and your fan’s manual.
• On multi-value capacitors, each lead corresponds to a specific capacitance section—keep those connections consistent.
• Before removal, take a clear photo or label wires so they return to the same points.

Turn off power at the breaker before handling any wiring. If colors or terminals don’t match your original setup, consulting a qualified electrician can help prevent miswiring.

Wire count indicates how many capacitance sections are inside and how your fan uses them.

• 2-wire: Single µF value for a basic start/run function.
• 3-wire: Two capacitance values share a common lead, often used to select between speeds.
• 4-/5-wire: Multiple µF values (for example, 4.5µF+5µF+6µF) provide more speed options via separate leads.

It’s advisable to choose the same wire count and µF combination printed on your original capacitor. Using a different configuration may not match your fan’s switch or control, which can affect speed selection. Matching the setup helps the pull chain, wall control, or remote work as intended.
