The ICM2807 is a low-cost replacement for the Carrier HK42FZ017 furnace control board which is used to control gas valve, ignitor, blower motor, inducer, humidifier and air cleaner.
Key Features & Benefits
Carrier-Focused Replacement
Made to replace specific Carrier furnace boards so you can swap the board and harness, without rewiring or retrofitting.
All-in-One Furnace Control
Controls the gas valve, inducer, blower, and ignitor all from one board for smooth, factory-style heating cycles.
Microprocessor-Based Reliability
Manages timing and safety checks digitally, cutting down on lockouts and giving more consistent performance.
LED Diagnostics
LEDs show fault codes for issues like ignition failure or pressure switch trips making it easier to pinpoint the problem fast.
Designed for Modern Safety Expectations
Watches all major safety circuits and shuts off gas fast if there’s no flame or ignition.
Compatible With Standard Thermostats
Works with 24V thermostats, so you can leave the wall control as-is during board replacement.
Twinning-Compatible
Works with another ICM2807 to control twin furnaces from one thermostat—ideal for dual-furnace systems.
Continuous Blower Speed Jumper
Built-in jumper lets you set a low, continuous fan speed for better air circulation and filtration without needing extra controls.
