Thermal Engineering Co. TS 50S Power Switch Repair Service

Professional diagnostic and board-level repair service for this Thermal Engineering Co. TS 50S Power Switch.

The Thermal Engineering Co. TS 50S is a 50‑amp automatic transfer switch (often a Todd Engineering model) that routes shore or generator power to a breaker panel and switches to inverter output when mains are lost. Common failure modes include worn relay contacts, intermittent AC‑relay operation under shore‑power load, and insulation breakdown on the internal wiring harness. Begin diagnostics by verifying 120/240 V input voltage and continuity of the transfer relays; then inspect contact surfaces for pitting or corrosion, and review any diagnostic LEDs or fault codes displayed on the unit’s panel.
