Ice O Matic 9181009-09 Capacitor Reference

What This Capacitor Does

A run capacitor delivers a continuous phase shift to help electric motors operate efficiently. It supplies steady electrical assistance while the motor turns.

A single run capacitor uses two terminals to connect into the motor circuit. If the part fails or loses its strength, the motor might struggle to start, overheat, or simply hum without spinning.

Understanding the 9181009-09 Specifications

When reading the label on part number 9181009-09, each printed specification defines how the component functions within your electrical circuit.

Always match these electrical ratings closely to ensure the motor operates as designed.

• Capacitance: 15.0uF. This rating must match the requirements of the motor circuit.
• Voltage: 440V. Replacement capacitors must have the same voltage rating or a higher one.
• Frequency: 50/60HZ. This indicates the alternating current power line frequency the unit accepts.
• Height: 5 in / 12.70 cm.
• Length: 9 in / 22.86 cm.
• Width: 6 in / 15.24 cm.

How to Confirm a Replacement Matches

Capacitor microfarads, written as uF or MFD, must always be the same as the rating on your old part. For this unit, the circuit requires 15.0uF.

Voltage must be the same or higher. For example, a 440 V capacitor can replace a 370 V one, but never the other way around.

The physical shape and size also matter. Capacitors are commonly round or oval. Pick the shape and dimensions that securely fit inside your equipment mounting bracket.

Signs of Failure and Safe Replacement Steps

A fan or motor that hums but will not spin is often caused by a bad capacitor rather than a bad motor. Physical bulging, leaking fluid, or a total loss of motor rotation can also indicate failure.

1. Shut off electrical power at the breaker box and any disconnect switch.
2. Use a meter to test for power and confirm the circuit is dead.
3. Discharge the capacitor terminals using an insulated tool before touching them.
4. Take a photo of the wire connections for reference.
5. Move wires one at a time to the same spots on the replacement unit.
6. Secure the capacitor into the mounting bracket and restore power to test operation.

Read your old part

1. Look at the label on your existing part to verify the part number is 9181009-09.
2. Check that the capacitance rating on the old unit reads 15.0uF or 15 MFD.
3. Confirm the voltage rating is 440V or that your system calls for 440V or lower.
4. Measure the bracket space to ensure the 5 in / 12.70 cm height, 9 in / 22.86 cm length, and 6 in / 15.24 cm width fit properly.
