Over time, any device starts to work not at full power or some breakdown might occur. In some cases, you can solve the problem yourself, and in some cases it is still worth to contact specialists. Below, you will find the most common breakdowns of air conditioners and advice from the manufacturer on how to fix the malfunction.

Air conditioner seems to run too much
| Check if ... | Then... |
|---|---|
| The current air conditioner replaced an older model | The use of more efficient components may cause the air conditioner to run longer than an older model, but the total energy consumption will be less. Newer air conditioners do not emit the “blast” of cold air you may be accustomed to from older units, but this IS NOT an indication of lesser cooling capacity or efficiency. Refer to the efficiency rating (EER) and capacity rating (in BTUs/hr.) marked on the air conditioner |
| The air conditioner is in a heavily occupied room or heat producing appliances are in use in the room. | Use exhaust vent fans while cooking or bathing and try not to use heat-producing appliances during the hottest part of the day. A higher capacity air conditioner may be required depending on the size of the room being cooled. |
Air conditioner cycles on and off too much, or does not cool/heat room in cooling/heating mode
| Check if ... | Then ... |
|---|---|
| FAN CONTROL is set to POWER SAVER (some models) | Use POWER SAVER only when you are away from home or asleep, since the fan does not circulate the room air continuously. Use LOW COOL, MED COOL (some models) or HIGH COOL for your best comfort. |
| The air conditioner is not properly sized for your room | Check the cooling capabilities of your room air conditioner. Room air conditioners are not designed to cool multiple rooms. |
| The filter is dirty or obstructed by debris | Clean the filter. |
| The inside evaporator and outside condenser coils are dirty or obstructed by debris. | Clean the inside evaporator and outside condenser coils. |
| There is excessive heat or moisture (open container cooking, showers, etc.) in the room. | Use a fan to exhaust heat or moisture from the room. Try not to use heat-producing appliances during the hottest part of the day |
| The louvers are blocked | Install the air conditioner in a location where the louvers are free from curtains, blinds, furniture, etc |
| The outside tempera ture is below 65°F (18°C) | Do not try to operate your air conditioner in the cooling mode when the outside temperature is below 65°F (18°C) |
| The temperature of the room you are trying to cool is extremely hot. | Allow extra time for the air conditioner to cool off a very hot room |
| Windows or doors to the outside are open | Close all windows and doors |
| The EXHAUST Control is set to OPEN | Set the EXHAUST Control to CLOSED for maximum cooling and/or heating |
| The THERMOSTAT Control is not at a cool enough setting | Adjust the THERMOSTAT Control to a cooler setting by turning the knob clockwise. Turn FAN CONTROL to HIGH COOL |
| The air conditioner is installed on the sunny side of your house | Install your air conditioner in a more shaded window. |
| The air conditioner in the heating mode has insufficient BTUs/hr for the heating requirements of the room | Do Not use the air conditioner as a primary source of heat. |
Water drips from cabinet into your house
| Check if ... | Then ... |
|---|---|
| The air conditioner is not properly leveled. The air conditioner should slope slightly downward toward the outside. | Level the air conditioner to provide a downward slope toward the outside (1⁄2 bubble on a carpenter’s level) to ensure proper drainage. Reposition or shim the cabinet as necessary. NOTE: Do NOT drill a hole in the bottom of the metal base and condensate pan. |
