We repair Ziehl-Abegg IGBT Cooling Fan (IE137-04) that stopped working and had unstable motor performance. Testing showed power circuit faults, capacitor failures, and regulator issues. These caused overheating and malfunction. Our engineers repaired the PCB, replaced defective parts, and tested the fan under load. After repair, the cooling fan achieved smooth and reliable operation.
Note: We are not manufacturers, we only repair.
