Luxaire Evaporator Coil Icing

Luxaire air conditioner freezes up; ice forms on the indoor coil or suction line.

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

Low airflow due to dirty filter or blower issue, Low refrigerant charge, Closed supply registers, Oversized metering device or TXV malfunction

Safety: Turn off cooling to prevent compressor damage.

Thaw the system: Turn thermostat to OFF and fan to ON. Allow several hours for all ice to melt.
Restore airflow: Replace filters, open all registers, and ensure blower is operating correctly.
Monitor operation: After thawing and restoring airflow, run cooling and watch for new ice. If icing returns, call a technician to check refrigerant charge and the Luxaire TXV.
