OEM Carrier Rectifier Control Board HK61EA003 for Model KFCEH3201F20

This is the genuine OEM rectifier control board (part number HK61EA003), the factory-specified replacement for the Carrier KFCEH3201F20 electric heating kit. The control board acts as the central command center for the heating system — managing rectifier logic, sequencing heating elements, and coordinating safety circuit communication. When this board fails, you may experience complete system lockout, no-heat conditions, erratic cycling, tripped limit switches that won't reset, or diagnostic fault codes that refuse to clear even after power cycling.

• Specs: OEM Part Number HK61EA003 | Rectifier control board | Factory-matched input/output voltages | Direct plug-and-play connector harness — no wire modifications required
• OEM vs Generic: This is a genuine Carrier factory board, not an aftermarket substitute. OEM boards undergo factory-level QC testing and are programmed with correct sequencing logic for the KFCEH3201F20. Generic boards often use off-spec components that introduce timing errors, nuisance lockouts, and premature failure — voiding equipment warranties in the process.
• Install Difficulty: 3/5 — Requires shutting off all power at the breaker and verifying zero voltage with a multimeter before handling. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring harness connections before disconnecting. Static discharge precautions recommended when handling the board.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders ship same business day from our stocked warehouse.
