American Farmworks 4400-B Electric Fencer Controller Repair Service

Professional diagnostic and board-level repair service for this American Farmworks 4400-B Electric Fencer Controller.

The American Farmworks 4400‑B is a high‑voltage electric fence energizer that delivers pulsed output through a 120 V AC or DC input to power the fence line. Common failure points include degraded capacitors in the pulse generator, worn transformer windings, and corroded contact terminals; these often manifest as reduced voltage output or intermittent operation. First‑check steps: verify the input supply (AC mains or battery) with a multimeter, inspect the main transformer and capacitor bank for bulging or leakage, and examine all solder joints and connectors for cracks or corrosion before proceeding to component replacement.
