Treadmill Breaker Trips or Fuse Blows

Answer: A shorted rectifier or surge suppressor on the board is pulling too many amps. Ship the control board to UpFix. We replace failed power parts, bench-test at load, and warranty the fix. 

Quick take: A home breaker that trips the instant you press “Start” usually means an internal short on the MCB, not a household wiring issue.

Common culprits

  • Bridge rectifier short

  • Metal‑oxide varistor (MOV) fail

  • Drive motor seized (less common test by spinning the roller by hand)

DIY checklist

  1. Inspect the treadmill’s own line fuse. If it’s blackened, a surge likely hit the board.

  2. Disconnect the motor leads; power the treadmill without them. Still tripping? The MCB is shorted.

Inside the UpFix repair

  1. Isolation & cleaning: Boards arrive pre‑logged in our ERP system with photos for insurance records.

  2. Short hunting: Automated trace‑resistance testing pinpoints the damaged leg.

  3. Surge defense upgrade: We replace MOVs with higher‑joule parts and add slow‑blow fuses where design allows.

Cost & turnaround

A new MCB from the treadmill maker can run $300–$600—if it’s in stock. UpFix repairs for a fraction, typically $99–$169, and ships within 1-3 business day.
