Reznor 110656 Relay

The Reznor 110656 Relay is a specialized 24V switching component designed for high-demand commercial and industrial HVAC applications. As a Single Pole Double Throw (SPDT) relay, it provides precise control over blower motors and fan circuits by toggling between normally open (NO) and normally closed (NC) contacts. This genuine OEM Reznor part is engineered to withstand the rigorous duty cycles typical of unit heaters and air handlers, ensuring reliable circuit switching without the chattering common in generic alternatives.

For technicians performing field repairs, the 110656 serves as the direct replacement for Reznor 105803. Its compact frame allows for straightforward integration into existing control cabinets where space is limited. The relay features standard spade terminals for quick termination, allowing you to restore system operation efficiently. Whether you are troubleshooting a 2-speed motor or a Reznor blower relay issue, this SPDT contactor delivers the electrical integrity required to maintain consistent airflow and safety logic in Reznor heating systems.

• OEM Compatibility: Specifically designed as the engineering-approved replacement for 105803 to ensure terminal alignment and electrical performance.
• Versatile SPDT Logic: Single-pole, double-throw configuration allows for seamless control of multiple outputs from a single 24V input.
• Industrial Durability: Constructed to endure the vibration and thermal stress found in gas-fired unit heaters and industrial air handlers.
• Simplified Installation: Features a high-visibility terminal layout to reduce wiring errors during HVAC relay replacement.

• Is this relay compatible with older Reznor units using part number 105803? Yes, the 110656 is the manufacturer-specified direct replacement for the 105803 relay.
• What is the coil voltage for this part? This is a 24V coil relay, standard for most Reznor low-voltage control circuits.
• What are the common symptoms of a failed Reznor relay? Typical failure points include burnt contact points causing the blower not to engage or a failed coil preventing the relay from pulling in when 24V is applied.
