Mitsubishi MSZ-FS06NA 6,000 BTU Compact Wall-Mount Indoor Unit E7 Error Fix: Indoor Fan Motor Error

Error code E7 on the Mitsubishi MSZ-FS06NA 6,000 BTU Compact Wall-Mount Indoor Unit means: Indoor Fan Motor Error. The indoor fan motor (cross-flow/tangential blower) has stopped or is not providing speed feedback to the control board. The motor may be mechanically locked by ice buildup, debris accumulation on the blower wheel, or a failed motor bearing. Check the blower wheel for heavy dust/mold buildup — this is the #1 cause. Verify the motor connector is securely plugged into the PCB. Test the motor winding resistance. On the indoor unit, the operation LED blinks in a pattern corresponding to this fault.
