Keeprite Outdoor Coil Frosting

Keeprite outdoor unit runs in cooling mode but frost or ice forms on the outdoor coil.

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 outdoor ambient temperature, Low refrigerant charge, Restricted airflow through condenser, Faulty fan motor running too slow

Safety first: Turn off power if heavy ice buildup is present.

Step 1 – Check outdoor temperature: If it's cool outside (near or below 60°F / 15°C), running the A/C can cause frosting. Avoid operating in low ambient conditions unless equipped with a low-ambient kit.
Step 2 – Clean coil and check fan: Clean the condenser coil and verify proper fan speed and direction.
Step 3 – Technician check: If frosting occurs in normal temperatures, a technician should check refrigerant charge and system operation.
