Troubleshooting and error codes

Problem Possible Causes What To Do
Zoneline does not start The 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.
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 should Indoor 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. Outdoor grille must have a minimum of 65% free area. Non-GE grilles may be too restrictive. Consult your salesperson.
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. See the Operating Instructions section.
The room may have been hot or cold. When the Zoneline is first turned on, 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 operation Dust is on the surface of the heating element. This can cause a "burning" odor at the beginning of heating operation. This odor should quickly fade.
The air is not always cool or hot during operation The 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.
The air does not feel warm enough during heating operation The 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 air The Smart Fan Auxiliary Controls may be set to cycle. See Smart Fan - Cooling/Heating on page 5.
The electric heating feature does not work 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.
Temperature display flashes The 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.
