Oval Single

Oval single-section capacitors are compact motor run components used on blower motors, condenser fan motors, and certain compressor applications. Their slim oval profile fits tight compartments and common strap brackets, making them an easy drop-in for many residential and light commercial systems.

Whether you are a DIY-capable homeowner, licensed contractor, property manager, or maintaining light commercial equipment, these capacitors restore proper startup torque and smooth operation when a fan or compressor struggles to start. Use them for replacing single-section oval motor run/start capacitors, blower or condenser fan capacitors, and to bring back dependable startup performance.

Selection is simple: match the microfarad (µF) rating and use an equal or higher voltage rating. These parts are not selected by SEER2, BTU, tonnage, or refrigerant; instead, go by the values on your old part or the motor/compressor nameplate. Also consider terminal style, case size for your bracket, tolerance, and temperature rating. Always disconnect power and discharge the capacitor safely before handling.

We stock popular values from leading names at a great price, typically $15-$65. Browse by brand-focused subcategories like Generic, ICM, Mars, and Supco to find a fast, in-stock replacement that keeps your system running.

Frequently Asked Questions

  • What is an oval single-section capacitor used for in HVAC systems?

    It provides phase shift and steady power for PSC blower and condenser fan motors, and some compressor applications.

  • How do I match the microfarad (µF) rating and voltage when replacing?

    Match the µF exactly (within tolerance) and choose an equal or higher voltage rating-never lower.

  • Are oval single capacitors interchangeable with round versions?

    Yes, if µF and voltage match and space/mounting allow; you may need a different strap or bracket.

  • What symptoms indicate a failing HVAC capacitor?

    Slow or non-starting fan, humming motor, warm motor shell, tripped breaker, or a swollen/leaking capacitor.

  • Can a DIY homeowner safely replace an HVAC capacitor?

    Yes, if comfortable with electrical safety: kill power at the disconnect and breaker, verify zero volts, and discharge.

  • Which brands of oval single capacitors are stocked in this category?

    Generic, Supco, ICM, and Mars are available in common ratings and case sizes.

  • What price range should I expect for a standard oval single capacitor?

    Most common values run approximately $15-$65, depending on rating and brand.

  • Do SEER2, BTU/tonnage, or refrigerant matter when choosing a capacitor?

    No. Capacitors aren’t rated by those metrics-select by µF, voltage, and physical fit.

  • Will a higher voltage rating (e.g., 440V replacing 370V) work?

    Yes, a higher voltage rating is acceptable if the µF matches; do not go lower than original.

  • How do I discharge and test a capacitor properly?

    After power is off, discharge with an insulated resistor, then check with a capacitance meter; replace if bulged or leaking.
