OEM Carrier Rectifier Control Board HK61EA003 for Model KFCEH2101F24

This is the factory OEM rectifier control board (part number HK61EA003) designed as a direct replacement for the Carrier KFCEH2101F24 electric heater kit. The rectifier control board manages the conversion and regulation of electrical current that powers the heating elements, sequencers, and safety circuits within the electric heat kit. When this board fails, you may experience symptoms including complete loss of heat, intermittent heating, tripped safety lockouts, or erratic sequencer operation that no amount of resetting will resolve.

• Specs: OEM Part Number HK61EA003 | Rectifier Control Board | Factory-matched electrical ratings | Direct plug-in replacement with no wiring modifications required
• OEM vs Generic: This is a genuine Carrier OEM board manufactured to exact factory specifications. Aftermarket control boards frequently use lower-grade rectifier components and may not replicate the precise sequencing timing, risking nuisance trips, heating element damage, or voided equipment warranties.
• Install Difficulty: 3/5 — Disconnect all power before servicing. Tools needed: Phillips and flat-head screwdrivers, needle-nose pliers, multimeter. Photograph all wiring harness connections before removal. Verify power is fully de-energized at the breaker — electric heat kits carry high-voltage circuits that require strict lockout/tagout procedures.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Carrier KFCEH2101F24 electric heater kit accessory. Always verify your existing board's part number against HK61EA003 on the board label or equipment data plate before ordering.
