30 day returns · Easy, with prepaid labels provided
Quick overview
- Compressor run capacitor Keeps the compressor motor running smoothly once it is up to speed.
- 80 uF at 440 VAC Match both numbers when replacing, since capacitance and voltage rating both matter.
- HeatPro application Listed for the Hayward HP21104T and HP21104TC HeatPro heat pumps.
- Genuine Hayward Factory part number SMX11022320.
- Common failure A weak capacitor shows up as a compressor that hums, trips the breaker or refuses to start.
- Discharge before handling A capacitor holds a charge after power is off, so treat it as live and have it discharged before touching the terminals.

Product details
The Hayward SMX11022320 is the compressor run capacitor for HeatPro heat pumps, rated 80 uF at 440 VAC. It is listed for the HP21104T and HP21104TC models.
What it does
A run capacitor stays in the circuit while the compressor is turning. It provides the phase shift the motor windings need to run efficiently. As the capacitor ages its capacitance falls, and the compressor starts drawing more current, running hotter and struggling to get going.
Symptoms and safety
Failed capacitors are one of the more common reasons a heat pump stops making heat. The compressor hums but will not start, or the unit trips its breaker shortly after calling for heat. A bulged or leaking case confirms it. Capacitors store energy after the power is switched off, so this is work for someone comfortable discharging one safely before the terminals are touched.
