H000051 Replacement Aftermarket dual run capacitor 80/5 MFD 370 VAC / 440 VAC for Raypak Heaters. Restores proper motor operation, reliable startups, and stable performance in Raypak heaters.
The Raypak H000051 Capacitor Kit is a dual run capacitor designed to restore proper electrical performance in compatible Raypak pool and spa heaters. Rated at 80/5 microfarads (MFD) and 370 VAC / 440 VAC, this capacitor plays a critical role in starting and maintaining consistent operation of heater motors and associated electrical components.
Capacitors are essential for providing the correct phase shift and voltage stabilization required for motors to start smoothly and run efficiently. When a capacitor begins to fail, heaters may experience hard starting, intermittent operation, humming noises, overheating, or complete failure to ignite or circulate properly. Replacing a weakened or failed capacitor with the Raypak H000051 helps return the heater to stable, reliable operation and prevents additional strain on motors and control components.
This OEM-spec capacitor is engineered to meet Raypak’s electrical and durability requirements, ensuring proper capacitance values, voltage tolerance, and long service life under pool equipment operating conditions. Using the correct H000051 capacitor helps protect the heater’s electrical system, improves energy efficiency, and reduces the risk of repeated breakdowns caused by incorrect or undersized aftermarket parts.

Installation & Important Notes
Installation requires working with high-voltage electrical components. Power must be fully disconnected before service. Proper wiring orientation and secure terminal connections are critical for safe operation. Professional installation by a qualified pool or HVAC technician is strongly recommended to ensure correct replacement and prevent equipment damage.
Please be advised that certain manufacturers - including Pentair® (with their TradeGrade® products), Jandy®/Fluidra® (with their Trade Series Exclusive™ products), and Hayward® (with their Expert Line® products) - do not honor manufacturer warranties on specific product lines purchased online.
These policies are intentionally enforced by the manufacturers to prevent customers from purchasing the same products at lower prices online.
Warranty coverage for these products is generally only available when purchased in person from an authorized local dealer.
While we strive to take care of our customers by offering the lowest possible prices on brand new, genuine products, we do not provide warranty coverage ourselves, nor can we guarantee that the manufacturer will honor the warranty on products purchased from our online store.
It is the buyer’s responsibility to confirm warranty eligibility directly with the manufacturer before making a purchase.
If you are a local customer, you may be able to purchase these items in-store and obtain manufacturer warranty coverage. However, for many of our customers across the country, paying significantly more locally just to access a manufacturer warranty often doesn’t make financial sense, especially when some local suppliers charge considerably higher prices.
By completing your purchase, you acknowledge and agree that we are not responsible for warranty support or claims denied by the manufacturer due to their online sales restrictions.
