Description
Overview
The Lennox 76F73 is a Double-Pole Single-Throw (DPST) heat sequencer relay engineered as a direct OEM replacement for Lennox electric heating systems. Heat sequencers are critical components in electric furnaces and air handlers, staging the activation of heating elements in a controlled sequence to prevent electrical overloads, reduce demand spikes, and extend the life of heating elements and contactors.
Key Features
- DPST (Double-Pole Single-Throw) switching configuration for reliable two-circuit control
- Functions as a heat sequencer relay to stage electric heating elements in sequence
- OEM Lennox replacement part — engineered to exact factory specifications
- Ensures smooth, staged startup of heating elements to protect electrical components
- Reduces peak current draw and prevents nuisance tripping of circuit breakers
- Designed for compatibility with Lennox electric furnaces and heating systems
- Durable construction for long service life in demanding HVAC applications
Application
The 76F73 heat sequencer relay is used in Lennox electric furnaces and air handlers where staged heating element activation is required. By energizing heating elements in sequence rather than simultaneously, the relay protects the electrical system from high inrush currents and ensures consistent, efficient heating performance.
Why Choose the Lennox 76F73
Using genuine OEM-specification replacement parts like the Lennox 76F73 ensures proper fit, function, and system reliability. Substituting non-compatible relays can result in improper sequencing, premature component failure, or system shutdowns. Trust the 76F73 to restore your Lennox heating system to factory performance.
