Product Description

This is an OEM Lennox Pellet Proof of Fire / Low Limit Switch that is found in several Lennox pellet stoves (see applicable models below). This is a genuine Lennox replacement part that will ship new in its original packaging, it is not an aftermarket copy.

Lennox Part Number: H5887 (Replaces old part number 32078)

Part Description: If you’re troubleshooting a Lennox pellet stove that shuts down after 10–15 minutes of operation, odds are the low limit (proof of fire) snap switch is the issue. This OEM sensor is designed to monitor exhaust temperature and kill power to the system if it drops below 140°F—a critical safety function that also helps prevent damage to internal components. With quality you can trust from Lennox, this switch helps maintain safe operation and reliable startup logic in your pellet stove. Don’t risk a misfire or shutdown—replace it right the first time.

Applicable Models:

Country Collection Pellet Stoves:

  • Bella
  • Winslow PS40
  • Winslow PI40

Lennox Elite Series Pellet Stoves:

  • Montage 32FS

Also commonly compatible with other Lennox-Whitfield pellet stoves, fireplace inserts, and zero-clearance units—verify your original part number before installing.


🛠️ Installation Notes for the Pro or DIY Tech:

  • Sensor is mounted on the combustion blower housing—easy access with basic tools

  • Two screws and two leads—a straightforward swap

  • Pro Tip: Always take a reference photo before disconnecting wiring to ensure correct terminal positioning


📋 Common Symptoms of a Failed Snap Switch:

  • Stove shuts down prematurely despite clean burn and good airflow

  • No visible damage, but sensor no longer responds to heat

  • Exhaust blower and feed system disengage too soon
