What it means

C203 is Outdoor fan error. The unit is stopping or limiting operation because that reading or component cannot be trusted. Manual trigger: C203 means Outdoor fan error.

Urgency

advisory

This is not usually an immediate safety hazard, but do not keep resetting it. Try only the safe homeowner check below; if the same code returns, schedule service.

Likely causes

  1. Debris, ice, or a foreign object restricting the fan
  2. Loose fan-motor plug, damaged fan lead, or bad feedback signal
  3. Fan motor winding, phase, or rotation fault
  4. Control board fan-drive fault after the motor checks out

Homeowner fix

Turn the unit off before looking at the outdoor fan area. Remove only loose debris outside the grille, restore power once, and stop if the fan still does not start or C203 returns.

When to call a pro

Call a licensed HVAC technician if C203 returns, the fan is not visibly blocked, or the fan blade is damaged. Tell them the code means Outdoor fan error.

Repair vs replace

Fan obstruction can be simple; fan-motor or outdoor-board repairs are technician work. Compare replacement only if major parts are quoted on older equipment.
