Parts to Your Door 51585 Flame Sensor 85 Series

Product Description

The PARTS TO YOUR DOOR 51585 is a replacement flame sensor designed for use in Peerless 85 Series boilers. The flame sensor detects the presence of a burner flame through electrical rectification and signals the control board to keep the gas valve open during normal operation. If the sensor fails or becomes coated with oxidation, the control will not prove flame and the system will lock out. This part is installed by licensed HVAC technicians and heating contractors performing routine maintenance or troubleshooting ignition failures on hydronic heating systems.

This flame sensor is suited for residential and light-commercial hydronic heating applications using Peerless 85 Series boilers. It is a direct replacement for Peerless part numbers 51585 and 760-401. Installers typically encounter this sensor during no-heat service calls where the boiler cycles on and off without sustaining ignition, or where the control board displays a flame-failure lockout code.

Key Features

• Direct OEM-style replacement for Peerless 51585 and 760-401 flame sensors
• Designed for the Peerless 85 Series boiler product line
• Restores reliable flame-proving signal to the ignition control board
• Addresses nuisance lockouts caused by a worn or oxidized sensor rod

Compatibility

Replacement for Peerless part numbers 51585 and 760-401, for use with Peerless 85 Series boilers.

Installation Notes

Flame sensor replacement is performed by a licensed HVAC technician or qualified heating contractor. Shut down the boiler and disconnect power before removing the existing sensor. The sensor rod should be inspected for oxidation and replaced rather than cleaned if wear is significant. Follow all applicable local codes and the boiler manufacturer's service documentation when performing ignition-system repairs.
