Unidad conectada (shore power), termostato OFF, pero A/C patina (cicla on/off).

Diagnóstico

"Sounds like thermostat or low voltage wiring problem. If turn electric off, investigate thermostat wires. If wires not touching, remove thermostat completely, cap all wires, turn power on. If unit doesn't come back on → needs new thermostat."

1. Apague breaker A/C (120 V).
2. Quite termostato → tape/cap TODOS cables (wire nuts).
3. Encienda breaker → ¿unidad arranca sola?
4. Si NO → termostato/cableado era causa. Reemplace termostato.
5. Si SÍ → fallo en placa control unidad techo (relé contactor pegado, señal parásita) → técnico.
