Heater shows E17 and stops; may be associated with very low ambient temperatures and ice buildup.

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

Defective defrost sensor, Blocked airflow across evaporator coil, Defrost algorithm error in PCB, Low refrigerant charge causing coil to freeze

Safety: Do not chip ice off the coil with sharp tools; this can puncture refrigerant tubes.

Steps:

Inspect coil: Look for heavy frost or ice on the Fairland evaporator coil.
Clear airflow: Remove any obstructions around the unit and clean the coil surface with warm (not hot) water if safe to do so.
Allow natural defrost: Turn the unit off and let it sit until all ice melts, then restart.

If E17 recurs:

A technician should test the defrost sensor, verify refrigerant charge, and check defrost parameters in the control board.
