Description
Lennox 56W63 Rollout Switch Overview
The Lennox 56W63 is a manual reset, single-pole single-throw (SPST) rollout switch engineered to protect furnaces and heating systems from the hazards of flame rollout. Designed as a direct OEM replacement for compatible Lennox equipment, this safety switch provides reliable, accurate over-temperature detection to keep your system operating safely.
How It Works
The rollout switch monitors the temperature near the burner assembly. If flame rollout occurs — a dangerous condition where burner flames extend beyond the combustion chamber — the switch trips at its rated setpoint of 400°F, immediately interrupting the circuit to shut down the burner. Because this switch features a manual reset design, the unit must be physically reset by a qualified technician after a trip event, ensuring the root cause is identified and corrected before the system is returned to service.
Key Features

Application
This rollout switch is intended for use in Lennox furnaces and heating appliances that require a 400°F manual reset SPST rollout safety switch.

Installation should be performed by a licensed HVAC technician in accordance with all applicable codes and manufacturer guidelines.
