Hayward Defrost Air Sensor for Heatpro & Summit Heat Pump SMX306000023

Description

Product Overview

The Hayward SMX306000023 defrost air sensor is engineered specifically for Hayward Heatpro and Summit heat pump models, providing a direct replacement for the original component. Constructed from high‑grade polymer housing and a precision‑calibrated sensing element, the sensor reliably detects low‑temperature conditions and triggers the pump’s defrost cycle at the optimal moment. Its compact dimensions—5.1 x 3 x 0.9 inches—and lightweight design (0.88 ounces) allow it to fit seamlessly into the existing sensor cavity without any modification to the pump housing. The sensor operates on a 12 V DC supply, matching the electrical specifications of the original part, and features a sealed connector that resists moisture ingress, ensuring long‑term durability even in harsh pool environments. Designed to meet or exceed OEM performance standards, this part helps maintain consistent water temperature while protecting the pump from ice‑related damage.

Usage

Installation of the SMX306000023 sensor is straightforward and can be completed by a qualified DIY enthusiast or a professional pool technician. The sensor is intended for use in residential and light‑commercial pool heating systems where Hayward Heatpro or Summit heat pumps are installed. It is ideal for climates that experience frequent temperature drops, as the sensor ensures the pump initiates a timely defrost cycle, preventing ice buildup on the heat exchange coil. The part is compatible with model HP21404T and other Heatpro/Summit variants that share the same sensor housing. Users should power down the pump, remove the old sensor, and install the new unit using the supplied mounting hardware. Once installed, the pump will automatically recognize the sensor and resume normal operation, delivering reliable heating performance throughout the swimming season.
