Description
The Lennox 14B05 is a 24-volt normally open (N/O) sequencer relay engineered as a direct OEM replacement for compatible Lennox heating systems. Sequencer relays are a critical component in electric furnaces and heat pump air handlers, staging heating elements in a controlled sequence to prevent voltage spikes, reduce nuisance tripping, and extend the service life of heating elements and electrical components.
Key Features
- OEM Lennox replacement sequencer relay
- 24-volt control voltage for compatibility with standard low-voltage thermostat circuits
- Normally open (N/O) contact configuration for sequential heating element staging
- Designed to prevent simultaneous energization of multiple heating elements
- Helps reduce electrical demand spikes and protects system components
- Direct drop-in replacement for Lennox electric furnaces and air handlers
Why Use the Correct Sequencer Relay?
Using the factory-specified sequencer relay ensures proper staging timing, correct contact ratings, and full compatibility with your Lennox control board and heating elements. Substituting incorrect relays can lead to premature element failure, nuisance breaker trips, or control board damage.
