1006801R Nordyne PCB, EHEAT & FSHE Single-Stage Control Board Product Overview 1006801R is an official OEM printed circuit board for single-stage electric heat (EHEAT) and fossil-fuel secondary heat (FSHE) applications in Nordyne furnaces and air handlers. It controls blower relay activation, heat-strip sequencing, safety interlocks, and provides on-board LED fault codes for rapid diagnostics. Optimized for Nordyne E7 series electric furnaces and B6 series high-efficiency air handlers, it ensures reliable performance in 10–23 kW systems.

Technician Notes Always de-energize power and discharge all capacitors before servicing. Use an ESD wrist strap and handle the PCB only by its edges to prevent static damage. Photograph or diagram original wiring harness, dip-switch settings, and jumper positions prior to removal. Replace the onboard 3 A fast-blow fuse if blown; confirm correct fuse type per OEM manual. Verify 24 VAC between R and C before power-up, then observe LED blink codes during startup. After installation, cycle a heat call to confirm blower activation and heat-strip sequencing at both EHEAT and FSHE stages. Use LED fault codes and 7-segment display readouts (if equipped) to troubleshoot relay or sensor faults—refer to the OEM service guide. Listen for crisp blower-relay clicks and consistent heat-strip engagement; reseat connectors if intermittent.
