Know before you buy
A failing capacitor often manifests as a compressor that struggles to start, makes a humming sound without engaging, or causes the heat pump to trip its breaker. If your unit is failing to heat or won't kick on, testing the capacitor is a standard first step in troubleshooting.
No, this specific part is designed for Hayward HeatPro models, including the HP21404T, HP21404TC, HP21004T, HP21254T, SUMXL112, SUMXL140, and HP21124T. Always verify your specific heat pump model number against the manufacturer's parts list before purchasing.
This is a non-polarized capacitor, meaning it does not have a positive or negative terminal. You can install it in either orientation without affecting the performance of your compressor.
This is an original equipment manufacturer (OEM) part designed as a direct replacement. It is engineered to fit your Hayward HeatPro unit exactly as the original component did, requiring no modifications for installation.
If you are comfortable working with electrical components, it is a straightforward replacement. However, because capacitors can hold a dangerous electrical charge even when the unit is unplugged, ensure you properly discharge the old capacitor before handling it, or consult a professional technician if you are unsure.
