OEM Carrier Rectifier Control Board HK61EA003 for Model EHK310B01

This is the factory OEM rectifier control board (part number HK61EA003) designed as the direct replacement for the Carrier EHK310B01 electric heat kit. The rectifier control board manages the conversion and regulation of electrical power to the heating elements, coordinating sequencer timing, safety circuit monitoring, and staged heat activation. When this board fails, common symptoms include complete loss of electric heat, erratic or intermittent heating cycles, tripped safety limits that won't reset, or the air handler running with no heat output despite a valid thermostat call.

• Specs: OEM part number HK61EA003 | Rectifier control board | Factory-matched for Carrier EHK310B01 electric heat kit | Engineered to factory voltage and sequencing tolerances
• OEM vs Generic: This is a genuine OEM Carrier board — not an aftermarket substitute. OEM control boards maintain exact sequencer timing and safety lockout thresholds. Generic or refurbished boards frequently introduce nuisance trips, miswired terminals, or firmware mismatches that can damage heating elements or void equipment warranties.
• Install Difficulty: 3/5 — Disconnect all power at the breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, a multimeter for voltage verification, and zip ties for wire management. Photograph all wiring harness connections before removal. Label each connector — control boards on electric heat kits carry multiple low- and line-voltage connections that must be matched precisely.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Ships same business day from our stocked warehouse.

Compatibility: Engineered specifically for the Carrier EHK310B01 electric heat kit. Always verify your existing board's part number against HK61EA003 and confirm unit voltage and sequencer configuration before ordering. Our parts specialists are available to verify fitment prior to purchase — don't guess on a control board. Order today and your part ships the same business day.
