Icm Controls icm2818 Furnace Control Board Nordyne Replacement

Product Description

The ICM CONTROLS icm2818 is an aftermarket furnace control board engineered to manage the core operating functions of a gas furnace. It sequences and controls the induced draft blower, circulator blower, gas valve, ignitor, and flame sensor based on signals received from the thermostat and onboard sensors. The icm2818 also provides integrated fault detection, communicating active and stored fault codes via an onboard LED indicator. When conditions require it, the board will initiate a timed safety lockout to protect the system and its components from damage.

This control board is intended for residential gas furnace applications where the original Nordyne-sourced board has failed or requires replacement. It is installed by licensed HVAC technicians during service calls or system repairs. The board is designed as a direct OEM-style replacement, fitting existing wiring harnesses and mounting provisions without modification in compatible Nordyne-platform furnaces.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local codes and the furnace manufacturer's service documentation.
