GoldStar air conditioner troubleshooting

All domestic air conditioners might face five types of malfunctions: a decrease in the efficiency of operation, a strong draft, leaks, the failure of the device (no reaction to remote controller commands), and unpleasant odor from the device. If you want to understand whether it is possible to fix the problem on your own, you need to identify the source of the problem.

ProblemPossible CausesSolutions
The air conditioner does not function.• No power supply.• Connect to power supply outlet and switch on.
• P2 flashes on the display screen.• Drain water.
• Timer-off is running.• You can turn on the unit three minutes later.
The air conditioner restart frequently.• In direct sunlight.• Close curtains.
• Windows or doors open, many people or a heat source in the room.• Close doors and windows, remove the heat source.
• Dirty filter.• Clean or replace the filter(s).
• Air inlet or air outlet blocked.• Remove the blockage.
The unit is too noisy.• Unit stands uneven.• Place on an even, solid surface (less vibrations).
No work of compressor.• Self protect of compressor.• Wait for 3 minute and restart again after the descend of tempereture. y

ProblemCausesWhat to do
The air conditioner is unplugged.■ The air conditioner is unplugged.• Make sure the air conditioner plug is pushed completely into the outlet.
Air conditioner does not start■ The fuse is blown/circuit breaker is tripped.• Check the house fuse/circuit breaker box and replace the fuse or reset the breaker.
■ Power failure.• If power failure occurs, turn the mode control to Off. When power is restored, wait 3 minutes to restart the air conditioner to prevent tripping of the compressor overload.
■ The current interrupter device is tripped.• Press the RESET button located on the power cord plug. If the RESET button will not stay engaged, discontinue use of the air conditioner and contact a qualified service technician.
■ Airflow is restricted.• Make sure there are no curtains, blinds, or furniture blocking the front of the air conditioner.
Air conditioner does not cool as it should■ The thermostat may not be set high enough.• Turn the knob to a higher number. The highest setting provides maximum cooling.
■ The air filter is dirty.• Clean the filter at least every 2 weeks. See the care and Maintenance section.
■ The room may have been • When the air conditioner is first hot. turned on, you need to allow time for the room to cool down.

Fan motor will not run.No powerCheck voltage at outlet. Correct if none.
Power supply cordCheck voltage to rotary switch. If none, check power supply cord. Replace cord if circuit is open.
Rocker switchCheck switch continuity. Refer to wiring diagram for terminal identification. Replace switch if defective.
Wire disconnected or connection looseConnect wire. Refer to wiring diagram for terminal identification. Repair or replace loose terminal.
Capacitor (Discharge capacitor before testing.)Test capacitor. Replace if not within ±10% of manufacturer's rating. Replace if shorted, open, or damaged.
Will not rotateFan blade hitting shroud or blower wheel hitting scroll. Re-align assembly.
Units using slinger ring condenser fans must have 0.22-0.25 inch clearance to the base.
If necessary, shim up the bottom of the fan motor with mounting screw(s).
Check fan motor bearings; if motor shaft will not rotate, replace the motor.
Fan motor runs.Revolves on overloadCheck voltage.
If not within limits, call an electrician.
Test capacitor.
Check bearings. Does the fan blade rotate freely?
If not, replace fan motor.
Pay attention to any change from high speed to low speed. If the speed does not change, replace the motor.
Fan motor noise.Tubo FanIf cracked, out of balance, or partially missing, replace it.
Axial FanIf cracked, out of balance, or partially missing, replace it.
Loose set screwTighten it.
Worn bearingsIf knocking sounds continue when running or loose, replace the motor. If the motor hums or noise appears to be internal while running, replace motor.
Compressor will not run, fan motor runs.VoltageCheck voltage. If not within limits, call an electrician.
WiringCheck the wire connections; if loose, repair or replace the terminal. If the wires are discon- nected, refer to wiring diagram for identification, and replace the wires. Check the wire connections; If not according to the wiring diagram, correct the connections.
Rocker SwitchCheck for continuity, refer to the wiring diagram for terminal identification. Replace the switch if the circuit is open.
ThermostatCheck the position of knob. If not at the coldest setting, advance the knob to this setting and restart the unit.
Check the continuity of the thermostat. Replace the thermostat if the circuit is open.
Capacitor (discharge capacitor before servicing.)Check the capacitor.
Replace if not within ±10% of manufacturer's rating, replace if shorted, open, or damaged.
CompressorCheck the compressor for open circuit or ground. If open or grounded, replace the compressor.
OverloadCheck the compressor overload if externally mounted. Replace if open. (If the compressor temperature is high, remove the overload, cool, and retest.)
Compressor cycles on overload.Fan motorIf not running, determine the cause. Replace if required.
Condenser air flow restrictionRemove the cabinet, inspect the interior surface of the condenser. If restricted, clean carefully with a vacuum cleaner (do not damage fins) or brush. Clean the interior base before re-assembling.
Condenser fins (damaged)If the condenser fins are closed over a large area on the coil surface, head pressures will increase, causing the compressor to cycle. Straighten the fins or replace the coil.
CapacitorTest the capacitor.
WiringCheck the terminals. If loose, repair or replace.
Refrigeration systemCheck the system for a restriction.
Insufficient coolingAir filterIf restricted, clean or replace.
Unit undersizedDetermine if the unit is properly sized for the area to be cooled.
Excessive noiseTurbo Fan or Axial FanCheck the set screw, or clamp. If loose or miss- ing, correct. If the tubo fan or axial fan is hitting scroll or barrier, rearrange the air handling parts.
Copper tubingRemove the cabinet and carefully rearrange the tubing not to contact the cabinet, compressor, shroud, and barrier.
