Endex DCMD76 Motor Controller Repair Service

Professional diagnostic and board-level repair service for this Endex DCMD76 Motor Controller.

Endex DCMD76 is a treadmill motor controller board used in Endex and compatible models such as DCMD66, DCMD86, and DK City treadmills. Common failure points include the magnetic speed sensor circuitry—often indicated by an E03 error code that causes the machine to run briefly then shut down—and power supply decoupling components that may burn out under voltage spikes. First‑check steps: verify 24 V DC input stability with a multimeter, inspect the motor driver ICs and surrounding capacitors for burn marks or bulging, and confirm the speed sensor leads are intact and properly seated on the motor shaft.
