Lennox 10B96 Sequencer
The Lennox 10B96 Sequencer is a critical field-replacement component designed for precise electric heat sequencing and blower motor control in residential air handlers. Featuring a single-pole, double-throw (SPDT) configuration, this 24V HVAC sequencer manages circuit activation with a specific timing profile: a 1 to 30-second ON delay and a 90 to 200-second OFF delay. These designated intervals prevent simultaneous high-draw electrical loads, protecting the transformer and preventing circuit breaker trips during startup. Often utilized as a Lennox heat strip relay, the 10B96 ensures the heating elements reach temperature before the blower engages, eliminating cold drafts. Built for durability in high-cycle environments, this electric furnace sequencer is compatible with various Lennox furnace parts and CB, CBH, and CBX series air handlers. For technicians performing HVAC contactor troubleshooting, verifying the internal heater resistance and timing tolerances of this 31L91 replacement is essential for restoring optimal furnace staging and airflow management.
- Staged Element Activation: Prevents electrical surges by managing the timing of heating elements and blower motor circuits.
- Precise Timing Specs: Factory-set for 1-30s ON and 90-200s OFF delays to ensure quiet and efficient system transitions.
- Universal Mounting: Standard bracket design allows for straightforward integration into existing control boards and cabinets.
- Broad Compatibility: Serves as a direct replacement for multiple Lennox and OEM part numbers, including 31L91 and 10B9601.
Common Questions
How do I verify if my sequencer is failing?
Technicians should check for continuity across the heater terminals and monitor the delay timing. If the blower remains on indefinitely or the heating elements skip staging, the resistance heater within the sequencer has likely failed.
Can this sequencer handle 240V circuits?
The control circuit operates on 24V, but the switched contacts are rated for line voltage applications typically found in residential electric furnaces and air handlers.
What causes the 10B96 to burn out prematurely?
Excessive cycling due to a faulty thermostat or loose electrical connections at the spade terminals can lead to overheating and mechanical failure of the internal bimetal strip.
