Aux ASW-H12B4-E Air Conditioner Troubleshooting

The motor is heard operating but the air-conditioner dose not work when the indoor unit is powered onSince the air-conditioner is powered on, it will come to working condition as long as you press the ON/OFF button of the remote control and the signal is well received.
The compressor stops running but the indoor fan motor keeps working when it is at cooling mode with the indoor temperature higher than set temperature.If you turn off the air-conditioner and restart it immediately, it will return to normal in3 minutes, after that, the air-conditioner will automatically adjust the indoor fan speed to what you set.
The compressor works discontinuously at dehumidifying mode.The air-conditioner will automatically control the working of the compressor according to the inside temperature
The air-conditioner dose not work while the LED display is on.The Timers set with the air-conditioner, it will be in hold on condition. If the TIMER setting is cancelled, the air-conditioner will return to normal working condition.
The compressor works discontinuously at cooling and dehumidifying mode, and the indoor fan motor slows down.The compressor stops internally or the fan motor slows down to prevent the indoor heat exchanger from being frozen.

Aux EA Series Air Conditioner Troubleshooting

ProblemPossible CausesWhat To Do
Zoneline does not startThe unit is unplugged.• Make sure the Zoneline plug is pushed completely into the outlet.
The power cord is not firmly attached.• Remove the room cabinet and make sure that the yellow connector on the end of the power cord is firmly engaged.
The fuse is blown/circuit breaker is tripped.• Check the house fuse/circuit breaker box and replace the fuse or reset the breaker.
The unit is waiting for the compressor overload protector to reset.• This is normal. The Zoneline will start again after it resets.
Power failure.• If power failure occurs, set the mode control to STOP. When power is restored, set the mode control to the desired setting.
• There is a protective time delay (up to 3 minutes) to prevent tripping of the compressor overload. For this reason, the unit may not start normal heating or cooling for 3 minutes after it is turned back on.
The current interrupter device is tripped.• Press the RESET button located on the power cord plug or the box near the plug.
• If the RESET button will not stay engaged, discontinue use of the Zoneline and contact a qualified service technician.
Zoneline does not cool or heat as it shouldIndoor airflow is restricted.• Make sure there are no curtains, blinds or furniture blocking the front of the Zoneline.
Outdoor airflow is restricted or recirculated.• Make sure the rear grille is not restricted. This can cause the unit to cycle off due to the compressor overload protector.
• Outdoor grille must have a minimum of 65% free area.
The temp control may not be set properly.• Turn the control to a lower or higher setting.
NOTE The temperature limiter may be limiting the temperature range.
The air filter is dirty.• Clean the filter at least every 30 days.
The room may have been hot or cold.• When the Zoneline is first turned on you need to allow time for the room to cool down or warm up.
Outdoor air is entering the room.• Set the vent control to the closed position.
Burning odor at the start of heating operationDust is on the surface of the heating element.• This can cause a "burning" odor at the beginning of the heating operation. This odor should quickly fade.
The air is not always cool or hot during operationThe heat pump is not producing hot air.• This is normal. The heat pump will produce warm air but not as hot as air produced when the higher-cost electric heat is used.
The Smart Fan Auxiliary Controls may be set to continuous fan.• This causes the fan to blow room temperature air even when the compressor or heater cycles off. The continuous air movement provides better overall temperature control in the cool mode.
The air does not feel warm enough during heating operationThe heat pump alone produces air that feels cooler than desired.• Use the Electric Heat Option. This turns off the heat pump and warms with electric heat only.
NOTE: Use of this option will result in increased energy consumption.
The unit is not blowing out airThe Smart Fan Auxiliary Controls may be set to cycle.
The electric heating feature does not workThe power cord is not firmly attached.• Remove the room cabinet and make sure that the yellow connector on the end of the power cord is firmly engaged.
Temperature display flashesThe compressor may have failed.• Set the operation control to STOP and then restart the unit. If the flashing light reappears within 30 minutes, call for service.

Air from unit does not feel cold enough.Turn selector to a higher COOL position.
Temperature selector set too warm. Set temperature selector to colder temperature.
Room temperature below 70° F (21 °C). Cooling may not occur until room temperature rises above 70 °F (21 °C).
Temperature sensing tube touching cold coil, located behind air filter. Straighten tube away from coil.
Air conditioner cooling, but room is too warm - ice forming on cooling coil behind decorative frontOutdoor temperature below 70 °F (21 °C). To defrost the coil, set selector to a FAN position. Then, set thermostat to warmer position.
Air filter may be dirty. Clean filter. To defrost, set selector to FAN.
Temperature selector set too cold for night-time cooling. To defrost the coil, set selector to a FAN position. Then, set temperature selector to warmer position.
Air conditioner cooling, but room is too warm - NO ice forming on cooling coil behind ecorative front.Dirty air filter - air restricted. Clean air filter.
Temperature selector set too warm. Turn temperature selector clockwise to a colder 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
