About the Dual Run Capacitor 55/5 MFD 370/440V Round

Where the Dual Run Capacitor 55/5 MFD 370/440V Round fits

Replacement parts have to match the original ratings exactly, not just look the same. For the Dual Run Capacitor 55/5 MFD 370/440V Round that means checking the electrical values and the physical fit against the original part number or the unit data plate before it goes in — a capacitor of the wrong microfarad rating or a motor with the wrong rotation will shorten the life of everything around it.

Most equipment failures are a single inexpensive part — a capacitor, a contactor, an ignitor, a flame sensor, a blower motor. Keeping the exact replacement on the truck turns a callback into a same-visit fix, which is why we stock the common failure parts for the equipment we sell.

What to check before you order

• Original part number or the equipment model number for cross-reference.
• Electrical ratings: voltage, amps, microfarads, horsepower, RPM and rotation as applicable.
• Physical fit: frame size, shaft, mounting and connector type.
• Power off and capacitors discharged before any replacement.

Installation and service notes

Photograph the wiring before removing the old part, transfer wires one at a time, and check that mounting and clearances match. Run the equipment through a full cycle after the swap and verify amperage against the data plate — a replacement that draws high current on day one is a sign of a mismatch or another failing component.
