Esp Probe (Red) 20087, replaces HARMAN 3-20-00844

Description

Equivalent To Harman/3-20-00844

The ESP (Exhaust Sensing Probe) Probe, commonly referred to as the “Red” ESP Probe, is a critical component in pellet stoves, particularly in Harman models. This sensor monitors the temperature of the exhaust gases and helps regulate the operation of the stove to ensure efficient and safe burning. When looking for an equivalent product to the ESP Probe 20087 that replaces Harman 3-20-00844, it’s essential to match the key specifications and features to ensure compatibility and reliable performance.

Key Specifications and Features:

• Sensor Type: Thermistor-based temperature sensor, designed specifically for monitoring exhaust gas temperatures in pellet stoves.
• Temperature Range: Typically calibrated to monitor exhaust temperatures ranging from low ambient temperatures up to around 500°F (260°C), which is standard for pellet stove exhaust systems.
• Response Time: Quick response to temperature changes to enable precise control of the stove’s operation.
• Connection Type: Usually equipped with a simple two-wire connection, often with quick-connect terminals for easy installation and replacement.
• Wire Length: Typically includes a sufficient length of high-temperature-resistant wire, usually around 18-24 inches, to reach from the sensor location to the control board.
• Probe Length: Standard probe length to fit securely into the exhaust manifold or flue pipe of the stove.
• Compatibility: Specifically designed to be a direct replacement for the Harman 3-20-00844, ensuring full compatibility with Harman pellet stoves and similar models.
• Color Coding: Often color-coded (red) to indicate its specific function and ensure correct identification during installation or replacement.

Applications:

• Pellet Stoves: Used primarily in pellet stoves, particularly Harman models, to monitor exhaust temperatures and ensure optimal combustion efficiency.
• Solid Fuel Appliances: Can be used in other solid fuel appliances where exhaust temperature monitoring is necessary for safe and efficient operation.

Additional Features:

• Durability: Built to withstand the harsh environment of pellet stove exhaust systems, including exposure to high temperatures, soot, and other combustion by-products.
• Accuracy: Provides accurate temperature readings to the stove’s control board, ensuring the appliance operates within safe and efficient parameters.
• Easy Installation: Designed for straightforward installation, often requiring no special tools or modifications to the stove.
• Safety: Plays a crucial role in the safety system of the pellet stove by helping to prevent overheating and ensuring that the stove operates correctly in all conditions.

Examples of Equivalent Products:

• OEM Harman ESP Probe (Red): The original equipment manufacturer (OEM) part that directly replaces the 3-20-00844, ensuring compatibility and performance.
• Aftermarket ESP Probe: Various aftermarket versions are available, designed to match the specifications of the OEM part, often at a lower cost while maintaining similar performance.

Installation and Setup:

1. Preparation:
   • Ensure the pellet stove is turned off, cool, and disconnected from the power source before starting the installation.
   • Gather the necessary tools, such as a screwdriver, for accessing the stove’s components.
2. Removing the Old ESP Probe:
   • Locate the existing ESP probe in the exhaust manifold or flue pipe.
   • Disconnect the wires from the control board.
   • Remove the probe by unscrewing or unclipping it from its mounting point.
3. Installing the New ESP Probe:
   • Insert the new probe into the exhaust manifold or flue pipe, ensuring it is positioned correctly.
   • Secure the probe using the provided mounting hardware.
   • Connect the wires to the control board, ensuring proper polarity and secure connections.
4. Testing the Installation:
   • Reconnect the stove to the power source and turn it on.
   • Monitor the stove’s operation, ensuring that the control board receives accurate temperature readings and that the stove operates as expected.

Maintenance Tips:

• Regular Inspection: Periodically check the probe for signs of wear or damage, especially if the stove experiences heavy use.
• Cleanliness: Keep the probe and its surroundings clean from soot and ash buildup to ensure accurate temperature readings.
• Replacement: Replace the probe as needed, particularly if you notice inaccurate temperature readings or erratic stove operation.

Conclusion:

This ESP Probe (Red) 20087, equivalent to the Harman 3-20-00844, is a vital component for maintaining the safe and efficient operation of pellet stoves. This equivalent product offers the same high-temperature monitoring capabilities, durability, and ease of installation as the original part. Proper installation and regular maintenance will ensure reliable performance and longevity of your stove.
