Lennox 39H98 Relay
The Lennox 39H98 Relay is an essential primary control component designed for reliable low-voltage switching in residential and light commercial HVAC equipment. This DPDT 24V Relay (Double-Pole Double-Throw) features a 24VAC coil, making it a versatile drop-in replacement for managing blower motors, fan cycles, and auxiliary heat circuits. Engineered for HVAC control circuit repair, the 39H98 manages power distribution across two separate circuits simultaneously, ensuring that critical furnace or air handler components engage and disengage with precision timing. Its compact footprint allows for easy mounting within existing control boards or electrical panels, maintaining the integrity of the OEM Lennox part specifications while providing a robust solution for inductive load switching.
Technical Application Benefits:
- Universal Compatibility: Optimized for use as a Lennox replacement relay in a wide range of furnace and heat pump models.
- DPDT Contact Configuration: Allows for complex switching logic, controlling two independent circuits from a single 24V signal.
- High Inductive Load Rating: Built to handle the high-current inrush typical of blower motors and compressors.
- Compact Form Factor: Facilitates standard mounting in crowded electrical compartments without obstructing airflow or other components.
Frequently Asked Questions:
Can the 39H98 replace a Single-Pole relay?
Yes, the DPDT switching logic allows you to use one side of the relay if the original part was only SPDT, provided the coil voltage and contact ratings match your system's requirements.
What are the symptoms of a failing HVAC relay?
Common signs include a "clicking" sound without component activation, burned contact points, or the blower motor failing to shut off after the thermostat call has ended.
Are the terminals marked for easy wiring?
Yes, this 24V HVAC relay features standard 1/4-inch quick-connect terminals designed for standard HVAC wiring harnesses, simplifying the field installation process.
