Luxaire Repeated Safety Lockouts

Luxaire air conditioner frequently goes into lockout and must be manually reset at the breaker or thermostat.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Intermittent high‑ or low‑pressure trips, Faulty pressure switch, Control board misinterpreting sensor data, Marginal refrigerant charge

Safety: Do not repeatedly reset without finding the cause; this can damage the compressor.

Record conditions: Note outdoor temperature, run time, and any error codes when lockout occurs.
Basic maintenance: Ensure filters and coils are clean and fans are operating correctly.
Professional diagnostics: A Luxaire‑trained technician should check pressures, switch operation, and board fault history to identify the root cause and replace any faulty switches or boards.
