This spill switch assembly is built for the Enviro Ascot gas stove and both steel and cast iron versions of the Enviro Westport, and fits 3 compatible models on record. The Enviro 50-885 Spill Switch Assembly with wiring harness replaces the worn vent safety switch component in compatible Enviro gas stoves.

Purpose

The spill switch monitors venting conditions and works with the wiring harness to signal the appliance control system if flue gases are not venting properly, helping the stove maintain correct operation.

Key Benefits

• Restores proper vent-safety monitoring for reliable appliance operation
• Genuine Enviro part matched to factory wiring and switch specifications
• Direct-fit for listed Ascot and Westport models — no modification needed
• Helps maintain consistent, efficient combustion performance

Other Notes

Because this is a gas-appliance safety component, installation should be performed by a licensed gas technician in accordance with local codes.

When replacing the spill switch assembly, it is also worth inspecting related gas parts such as the pilot assembly, thermocouple, or gas valve for wear, since these components work together in the same safety and ignition system.
