ICM Controls ICM2805A Application/Install Guide

  • Hello! I've reviewed the Installation, Operation & Application Guide for the ICM2805A Furnace Control Board. This document provides detailed instructions for installing the board across various furnace models, including specific modification steps for some models. It also outlines the LED fault codes for troubleshooting. I'm ready to answer your questions about this product and the information provided in the document.
  • What should I do before installing the board?
    What models does this board support?
    What does a blinking red LED indicate?
    What is the warranty period for this product?
