What's wrong?
The affected part is the circuit breaker for the power sofa in 2025 Thor Motor Coach Sanctuary and Tranquility motorhomes. A breaker sits in the main fuse panel and protects the wiring by opening the circuit when electrical current rises above the safe limit. For this sofa circuit, the wiring was designed to be protected by a 20 amp breaker.
On affected motorhomes, production installed a 50 amp breaker in that location instead. Because the breaker rating is too high for the circuit, the wiring can carry more current than it was designed to handle before the breaker opens. That mismatch can overheat the wiring in the power sofa circuit.
Owners can check the main fuse panel for the power sofa breaker. The incorrect breaker has "50" stamped into the lever, while the correct breaker for this circuit is rated at 20 amps.
Who's affected?
Both included models use the same manual-reset breaker in the wiring circuit.
