Icm Controls icm281 Furnace Control Module Direct Wire Replacement

Product Description

The ICM Controls icm281 Furnace Control Module is a direct wire-for-wire replacement control board designed for residential and light commercial gas furnace systems. This module is built to replace many popular OEM furnace control boards, making it a practical choice for HVAC technicians who need a reliable, cost-effective solution without reconfiguring existing wiring. The icm281 simplifies field replacement by matching the original wiring layout, which reduces diagnostic time and gets the system back online faster.

This furnace control module manages the core functions of a forced-air gas furnace. It sequences the ignition, controls the inducer motor, operates the gas valve, and manages both heating and cooling blower functions. The board operates on a line voltage input of 98 to 132 VAC at 60 Hz, making it compatible with standard residential electrical systems. The ignitor output is rated at 5A at 120 VAC, supporting hot surface ignitor setups commonly found in modern furnaces.

A key safety feature of the icm281 is its 100 percent gas shutoff function. If ignition fails, the board cuts gas flow immediately to prevent unburned gas from accumulating. This lockout protection is critical for safe furnace operation and meets the expectations of professional HVAC installers and service technicians.

The cool blower output is rated at 30A, 2 horsepower, 240 VAC, giving it the capacity to drive larger blower motors used in multi-zone or higher-capacity systems. The heat blower circuit supports 5A at one half horsepower at 240 VAC. The inducer motor terminal handles 4A full load amps with an 8.0 amp locked rotor rating at 120 VAC. The gas valve circuit operates at 1.5A at 30 VAC, which is standard for most residential gas valves. The module is rated for an operating temperature range of negative 40 to 176 degrees Fahrenheit, allowing reliable performance in attic installations, crawlspaces, and cold-start environments.

• Direct wire-for-wire OEM replacement simplifies installation and reduces labor time
• Built-in 100 percent gas shutoff on ignition failure for enhanced system safety
• Wide operating temperature range of negative 40 to 176 degrees Fahrenheit suits demanding installation environments

Product Highlights

The ICM Controls icm281 delivers a reliable, safety-equipped furnace control module that drops in as a direct replacement for many OEM boards, cutting diagnostic complexity and downtime for HVAC professionals.
