Capacitors give motors the push they need to start and help them run steady. If you are holding an old part with this number, checking the printed details helps ensure a safe, accurate match.

Safety first. Turn off power at the breaker and outdoor disconnect, then test for power before touching any wires. A capacitor can hold a charge even with the power off. It must be discharged with an insulated tool before anyone touches its terminals. Take a photo of every wire before removing the old part so you can place each wire on the correct terminal.

What this capacitor does

A capacitor provides an electrical boost to motor windings. It gives the motor a push to start up and helps keep it running smoothly during normal operation.

When a capacitor gets weak or fails completely, connected motors may struggle. A fan motor that hums but will not spin is often caused by a bad capacitor rather than a bad motor.

Understanding the part specs

Every capacitor has physical and electrical limits. Replacement parts must fit the existing mounting bracket and match the circuit demands.

Part number 1067-00001-00 lists the following physical measurements and electrical ratings:

  • Voltage: 120Vac
  • Height: 1.95 in / 4.95 cm
  • Length: 5.1 in / 12.95 cm
  • Width: 2.05 in / 5.21 cm

Confirming the right match

Matching a capacitor requires checking capacitance, voltage, and physical size. The microfarad rating, written as µF, MFD, or uF, must match your old part exactly.

Voltage ratings can be the same or higher, but never lower. For example, a 440 V capacitor can replace a 370 V capacitor, but never the other way around. Also check the physical shape, whether round or oval, so the unit fits securely inside your equipment mounting bracket.

Safe replacement steps

Replacing a capacitor is straightforward if you handle electrical safety properly. Never touch the terminal posts until the unit has been safely discharged.

  1. Shut off electrical power at the main breaker box and the equipment disconnect switch.
  2. Test the circuit with a voltage meter to make sure no power is present.
  3. Discharge the capacitor terminals using an insulated tool before touching them.
  4. Take a clear photo of the wiring setup to document where each wire connects.
  5. Move wires one at a time from the old terminals to the matching spots on the replacement unit.
  6. Mount the capacitor securely in its bracket and close all service panels before restoring power.

Read your old part

  1. Read the printed part number on the old capacitor label to confirm it shows 1067-00001-00.
  2. Verify the voltage rating on your original part matches the 120Vac rating.
  3. Check the µF rating to ensure it matches the microfarad value listed on your original part.
  4. Measure the old case dimensions against the height of 1.95 in / 4.95 cm, length of 5.1 in / 12.95 cm, and width of 2.05 in / 5.21 cm.
  5. Confirm the shape matches your equipment bracket so the new part mounts securely.

When to call a pro

Hire a licensed HVAC technician for any step you are not sure you can do safely. If you cannot test for voltage, discharge the capacitor safely, or identify the wiring connections, stop and call a professional.

Questions

Can a capacitor hold power when the unit is unplugged?

Yes. A capacitor can hold a charge even with the power off. It must always be discharged with an insulated tool before anyone touches the terminals.

Why does my fan motor hum but refuse to spin?

A fan that hums but will not spin is often caused by a bad capacitor rather than a bad motor. When the capacitor fails, it cannot provide the electrical push the motor needs to start turning.

Can I use a capacitor with a higher voltage rating?

Yes. Volts must be the same or higher. For example, a 440 V capacitor can replace a 370 V one, but you must never use a part with a lower voltage rating.

Does the shape of the capacitor affect how it works?

Round and oval capacitors with the same electrical ratings do the same job. You simply need to pick the physical shape that fits your mounting bracket.
