Weslo #WLTL20550 INTP12C 117860 Power Supply board Repair Service

Professional diagnostic and board-level repair service for this Weslo #WLTL20550 INTP12C 117860 Power Supply board.

Weslo #WLTL20550 is a treadmill power‑supply board (INTP12C 117860) that converts mains voltage to the low‑voltage rails used by the motor controller, display, and safety circuits. Common failure points on this board include burnt or cracked capacitors, failed MOSFETs or switching transistors, shorted windings in the transformer, and damaged diode bridges; these often manifest as no power to the treadmill, overheating of components, or erratic motor behavior. First‑check diagnostics: verify that the mains input is present and within spec (120/240 V ±10 %); measure output rail voltages against the service manual tolerances; visually inspect for bulging capacitors, burn marks, or loose solder joints; and review any error codes displayed on the treadmill console.
