T92S7D22-22 OEM Furnace Relay Casalytics DPST General Purpose

Description

Product Overview

The T92S7D22-22 OEM replacement furnace relay from Casalytics is engineered to meet the exact specifications of the original equipment manufacturer, ensuring a seamless fit and reliable operation in any standard residential heating system. This dual‑pole single‑throw (DPST) relay provides two independent switching contacts that open and close simultaneously, delivering precise control over furnace igniters, blower motors, and safety switches. Constructed from high‑grade copper contacts and a robust polymer housing, the relay is designed to withstand the high‑temperature environment of a furnace while maintaining consistent electrical performance over thousands of cycles. Its compact dimensions—2.87 x 1.54 x 1.54 inches—and lightweight design (3.21 ounces) make it easy to handle and install without the need for additional mounting hardware. The relay’s rating of 120 V AC at 5 A ensures compatibility with most common furnace control circuits, while its sealed enclosure protects against dust, moisture, and vibration, extending service life and reducing the likelihood of premature failure.

Usage

This relay is intended for use in a wide range of heating applications, including forced‑air furnaces, gas‑fired boilers, and electric heat pumps that rely on precise timing and safety interlocks. It is an ideal replacement for homeowners performing routine maintenance, as well as for professional HVAC technicians who need a dependable part that matches OEM quality. The DPST configuration allows the relay to simultaneously control the furnace igniter and the blower motor, ensuring that the blower only operates when the flame is established, which improves energy efficiency and reduces wear on mechanical components. Installation is straightforward: simply disconnect power, remove the existing relay, and insert the T92S7D22-22 in the same orientation, reconnecting the wiring terminals as labeled. The relay’s universal pin layout matches the standard furnace relay socket, eliminating the need for adapters or rewiring. It performs reliably in environments ranging from temperate residential basements to harsher commercial settings where temperature fluctuations and dust exposure are common.
