Climatemaster CS17B0003N03 Electric 2 Heat Control Board

Product Description

The CLIMATEMASTER CS17B0003N03 is a genuine OEM replacement electric two-heat control board designed to manage heating sequences in compatible heat pump or electric heating systems. The board governs staging logic for dual electric heat strips, coordinating timing and sequencing to maintain safe, consistent operation. Licensed HVAC technicians performing board-level diagnostics or field replacements will find this a direct OEM-specification swap. As a genuine replacement part, it is built to the original design tolerances and does not require modifications to the existing wiring harness or control circuit.

This control board is suited for residential and light-commercial electric heating applications that rely on staged electric resistance heat. It is intended for systems configured with two stages of electric heat, such as those using sequenced heat strip assemblies in fan coil or air handler units. Installers working on ClimateMaster equipment should verify the part number against the existing board label before installation.
