To perform the correct repair of the air conditioner, you will need a troubleshooting table – it will help to understand the cause of the device failure based on the symptoms you noticed. Here, you will also find possible ways of troubleshooting.
Frigidaire wall air conditioner troubleshooting
|Air conditioner will not operate.||Wall plug disconnected. Push plug firmly into wall outlet.
Plug Current Device Tripped. Press the RESET button.
House fuse blown or circuit breaker tripped. Replace fuse with time delay type or reset circuit breaker.
Control is OFF. Turn Control ON and set to desired setting.
|Air from unit does not feel cold enough.||Room temperature below 16°C (60°F). Cooling may not occur until room temperature rises above 16°C (60°F).
Temperature sensing element touching cold coil, located behind air filter. Straighten 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.
|Air conditioner cooling, but room is too warm - ice forming on cooling coil behind decorative front||Outdoor temperature below 16 °C (60 °F). To defrost the coil, set FAN ONLY mode.
Air filter may be dirty. Clean filter. Refer to Care and Cleaning section. To defrost, set to FAN ONLY
Temperature is set too low for night-time cooling. To defrost the coil, set to FAN ONLY mode. Then, set temperature to a higher setting.
|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 unit is blocked by drapes, blinds, furniture, etc. - restricts air distribution. Clear blockage in front of unit.
Doors, windows, registers, etc. open - cool air escapes. Close doors, windows, registers, etc.
Unit recently turned on in hot room. Allow additional time to remove "stored heat” from walls, ceiling, floor and furniture.
|Air conditioner turns on and off rapidly.||Dirty air filter - air restricted. Clean air filter.
Outside temperature extremely hot. Set FAN speed to a faster setting to bring air through cooling coils more frequently.
|Noise when unit is cooling.||Air movement sound. This is normal. If too loud, set to lower FAN setting.
Window vibration - poor installation. Refer to installation instructions or check with installer.
|Water dripping INSIDE when unit is cooling.||Improper installation. Tilt air conditioner slightly to the outside to allow water drainage. Refer to installation instructions or check with installer.
|Water dripping OUTSIDE when unit is cooling.||Unit removing large quantity of moisture from humid room. This is normal during excessively humid days.
|Remote Sensing Deactivating Prematurely (some models).||Remote control not located within range. Place remote control within 6 meters & 120° radius of the front of the unit.
Remote control signal obstructed. Remove obstruction.
|Room too cold.||Set temperature too low. Increase set temperature.
Remote Sensing activated (on some models) and remote control located in Hot Spot - Relocate remote control or deactivate remote sensing.
