Room temperature below 17 C(62 F). Cooling may not occur until room temperature rises above 17 C(62 F).
Temperature sensing element touching cold coil, located behind air filter. Straighten tube away from coil.
Reset to a Lower temperature.
Compressor shut-off by changing modes. Wait approximately 3 minutes and listen for compressor to restart when set in the COOL mode.
Problem: Air conditioner cooling, but room is too warm- ice forming on cooling coil behind decorative front.

Thermostat set too cold for night-time cooling. To defrost the coil, set to FAN ONLY mode. Then, set temperature to a Higher setting.
Problem: Air conditioner cooling, but room is too warm- NO ice forming on cooling coil behind decorative front.
Dirty air filter- air restricted. Clean air filter. Refer to Care and Cleaning section.
Temperature is set too High, set temperature to a Lower setting.
Air directional louvers positioned improperly. Position louvers for better air distribution.
Front of units is blocked by drapes, blinds, furniture, etc. – restricts air distribution. Clear blockage in front of unit.
Doors, windows, registers, etc. Open- cold air escapes. Close doors, windows, registers.
