Lennox 37H96 Relay

As a field tech, you know that keeping a service truck stocked with reliable switching components is non-negotiable. The Lennox 37H96 Relay is a heavy-duty 24V HVAC control component engineered for high-cycle applications in both residential and light commercial equipment. This DPDT (Double-Pole, Double-Throw) relay provides the versatile circuit management needed for multi-stage systems, blower motor control, and interlocking safety circuits. With a 13 Amp contact rating, it handles operational loads with minimal heat generation, replacing older Lennox 37H9601 units seamlessly.

The 37H96 control relay features 1/4-inch quick-connect terminals for fast field wiring and a compact footprint designed for standard mounting brackets. Its 24VAC coil is optimized for 50/60 Hz operation, ensuring compatibility with the majority of Lennox air handlers and furnaces. When you are troubleshooting intermittent signal failures or stuck contacts, switching to this genuine OEM Lennox part ensures the precision timing and electrical isolation required to protect sensitive control boards and compressors from back-EMF or voltage spikes.

• Direct OEM Compatibility: Ensures fit and function across hundreds of Lennox models including CHA24 and GCS16 series.
• Dual Independent Switching: The DPDT configuration allows for simultaneous control of two separate circuits, ideal for complex blower and exhaust sequences.
• High Current Capacity: Rated for up to 13 Amps, providing a robust bridge between low-voltage thermostats and high-voltage components.
• Universal 24V Logic: Works with standard 24-volt control transformers found in almost all modern HVAC platforms.
• Industrial Build Quality: Encapsulated coil and reinforced contact points designed to withstand the vibration of cabinet-mounted environments.

Can the 37H96 replace a single-pole relay?
Yes, because this is a DPDT relay, it can be used for SPST or SPDT applications by utilizing only the necessary terminals, making it a versatile truck-stock item.

What are the terminal specifications?
The Lennox 37H96 uses standard 0.25-inch spade terminals, common in most Lennox electrical repairs for easy "plug-and-play" replacement.

Is this relay suitable for 50Hz applications?
Yes, it is rated for 50/60 Hz, making it suitable for a wide range of international and specialized equipment configurations.
