PU-CB98 / PU-CBHS Control Board Heat Sensor

Key Features

• Precision Thermal Monitoring: Provides real-time heat data to the control board, allowing the stove to accurately determine when to activate the room air blower or trigger a safety shutdown.
• Plug-and-Play Connector: Equipped with a standard white plastic molex-style connector for a direct, secure interface with the Englander control board, requiring no wire stripping or crimping.
• High-Temperature Insulation: Features high-grade insulated lead wires designed to withstand the intense radiant heat within the stove's internal cabinet without melting or shorting.
• Durable Thermistor Probe: The sensor tip is encased in a corrosion-resistant metal housing to protect the sensitive electronics from the abrasive nature of pellet ash and soot.

Compatibility & Fitment

This heat sensor is compatible with a wide array of pellet and multi-fuel stoves manufactured by England Stove Works (ESW). Key compatible models include:

• Englander Pellet Stoves: 25-PDV, 25-PDVC, 25-EP, 25-EPI, 25-IP, 25-PAF, 25-PFS, 25-PI, 25-PUF.
• Multi-Fuel Models: 10-CDV, 10-CPM.
• Brand Cross-Compatibility: Also fits Summers Heat (SHP/SHP series) and Timberland (TRP series) models that share the Englander chassis designs.

When to Replace

• "E-1" or "E-2" Error Codes: The digital display on the control board shows an error code indicating the sensor circuit is either open (disconnected) or shorted.
• Room Blower Failure: The fire is burning hot, but the room air fan never turns on to distribute heat, suggesting the sensor isn't telling the board the stove is warm.
• Stove Shuts Down Early: The stove enters the startup sequence but shuts down after 15–20 minutes because it fails to detect a rise in temperature.
• Visible Heat Damage: The sensor wires are melted, charred, or have been pinched in the stove’s side panels or by the auger motor.

Installation Tips

• Power Down: Always unplug the stove and let it cool completely before opening the side or rear access panels.
• Probe Placement: The sensor is typically mounted on the exhaust blower housing or a nearby firewall. Note the exact orientation of the old probe before removing the mounting screw to ensure accurate readings from the new unit.
• Wire Routing: Avoid routing the wires near the exhaust pipe or moving parts like the auger shaft. Use high-heat zip ties to keep the wiring harness clear of hot surfaces.
• Secure Connection: Ensure the molex connector is pushed all the way into the control board until it clicks; a loose plug is a common cause of intermittent "E-1" errors.
• Clean the Area: While the stove is open, use a vacuum to remove ash buildup around the sensor mounting point, as excessive ash can insulate the probe and cause sluggish performance.
