Problem:Solution:
Initial TestingIf a compressor failure is suspected, several simple checks should be done initially to make sure that the right course of action is being taken. The following is a list of items and points that should be looked at before a determination is made of the condition of the compressor.
• Is the correct voltage available at the unit? Using a volt/ohm meter, check the voltage and compare with the voltage specified by the manufacturer (found on the data plate on the unit). Many compressors are replaced only to find later that there was either no power or incorrect power available to the unit.
• Is the contactor closing? Check to make sure that there is 24 volts at the coil side of the contactor. Check to make sure the points in the contactor are in good condition. Are they pitted or corroded to the point where they no longer conduct electricity?
• Is the capacitor in good condition? Does it have the correct rating for the application? Using a meter, determine if it still has the correct capacitance.
• The last of these initial tests to do is a touch test. This should be done very carefully as the compressor can become very hot in certain situations. This information may be helpful if further tests are needed to determine the condition of the compressor.
Further TestingUse extreme caution when conducting the following tests. The power must be turned off before continuing with the testing.
Checking Continuity
1. Remove wires from the fusite plug in the compressor, recording the location of each wire as it is removed. If a wire is misplaced when the
test is complete, serious damage could be done to the compressor.
2. Set an ohm meter to the lowest possible setting. On a note pad, write the following: “C to ground", “S to ground” and “R to ground.”
3. Using the ohm meter, check for continuity between C terminal on the fusite plug and the case of the compressor (a spot may have to be cleaned on the compressor to get a good reading.) Record what was observed on the note pad next to the heading *C to ground”. Do the same to the other two terminals and record the findings in the proper places.
4. If any sign of continuity between any of the terminals and ground was observed, recheck the terminal to confirm that the readings were correct. Any indication of continuity between any of the terminals and ground would point to an internal winding being shorted to the compressor case. This suggests that the compressor has an internal failure and it would need to be replaced.
5. If no continuity is noted between any of the terminals and ground, the compressor must be checked out further.
Checking WindingsThe following test is used to check the condition of the internal start and run windings.
1. Write the following down: “C to S’, “C to R" and “S to R."
2. Using the volt/ohmmeter, measure the resistance between terminals C and S. Record the findings on the note pad in the correct place.
Measure and record the resistance between the remaining terminals in the same manner.
Checking the Thermal Overload DeviceIf during the time that resistance was being checked in the previous test infinity was ever registered (meter indicated no continuity), the assumption could be made that there is an open winding (or a break in the wires of the winding). This may indicate that the windings had burned out and that the compressor had failed.
In the motor windings there is a thermal overload device. This device is designed to open if the internal temperature of the windings exceed preset limit. Since the resistance reading of a winding where the thermal overload device has opened would show no resistance, the assumption would most likely be made that the winding was burned out. This is where the temperature of the compressor as noted in the touch test becomes very important. If at the time of the touch test the compressor was found to be very hot, then there is a good chance that the thermal overload protector has opened. Before the compressor can be condemned as having a burned out start or run winding, it must be determined that the overload switch is in fact closed. It may take several hours for the compressor to cool down enough to guarantee that the switch has closed. After enough time has elapsed for the switch to close, the resistance between each of the terminals should be measured. It may be found that with the overload switch closed, the compressor checks out electrically sound. If this is the case, then other possibilities have to be looked at as to what caused the compressor to overheat.
There are several reasons why a compressor would overheat. If the capacitor was incorrect or failing, the amp draw (current flow) would be increased. This could cause the motor to heat up very rapidly, activating the thermal overload protection device. This would interrupt power and protect the motor windings from damage.
A loss of charge could also cause the operating temperature of the compressor to rise and open the thermal overload switch.
Restricted airflow through the coil could also cause the operating temperature of the unit to rise.
It is important to perform these checks before making a decision as to the condition of the compressor. An open thermal overload device in a motor does not mean that the motor was damaged or harmed in any way.

Aux air conditioner Troubleshooting

If the air conditioner does not switch on, there might simply be no voltage or the batteries on the remote controller might be dead. There are many simple malfunctions that can be fixed quickly and without any additional help. Look at the list of the malfunctions below.

AUX ALCA-HR1AA air conditioner troubleshooting

Problem Causing explanation
High outside temperature and too many indoor individuals, even air conditioner runs at full-load operation, the wind blowing out from air outlet is cold, but it is difficult to lower the indoor temperature, this is not malfunction.When the outdoor temperature is higher, more heat penetrates into indoor space, which increases the cooling load of AC. If there are too many individuals(for example 10 individuals) and every individual gives off 120W, totally 1200W, this will running out of half of AC cooling capacity, and the unit’s cooling capacity this time is far from enough, indoor temperature is hard to lower down. It is normal phenomenon and do not mean useless of AC.
Power voltage is too low, causing AC uneasy to start and shut down after starting, or fuse be burned out etc.It is not malfunction, need to find out the causing, if the causing is the electricity net voltage is too low, user should load a power manostat to keep voltage between 220V-380V for AC normally running
Select high wind speed but indoor temperature still at high side, air flow from the air outlet is too weak.It is because air filter is too dirty or blocked making cooling capacity fail to be brought by air flow, causing cooling capacity inadequate. Take out filter and wash, the problem will be solved.
Select high wind speed, the vibration and sound of unit are severe.Fan runs at high speed, severe vibration and sound of unit is normal phenomenon
Temperature controller adjusts improper and max cooling capacity is not utilized completely, thus indoor temperature can’t lower down.Adjust the temperature controller, and problem will be solved.
As for Heat pump air conditioner heating effect is not ideal during cold winter, this is normal phenomenon.The lowest temperature is — 7°C when heating, below this temperature unit cannot heat effectively.
Improper installation will lead to indoor temperature uneven or bad cooling effect.It is necessary to adjust AC installation position

WATER DRIPPING OUTSIDEExcess water may overflow in excessively hot and humid weather. This is normal.
WATER DRIPPING INSIDEAir conditioner must be installed level for proper water disposal.
WATER IN BASE PAN (ON OUTDOOR SIDE)This is normal for a short period in areas with little humidity; normal for a longer period in very humid areas. Moisture removed from indoor air drains to rear of cabinet where it is picked up by a fan and thrown aeainst the outdoor condenser coil.

GE Zoneline AZ55H12EAB air conditioner troubleshooting

ProblemPossible CausesWhat To Do
Zoneline does not startThe unit is unplugged.• Make sure die Zoneline plug is pushed completely into the outlet
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 mcxle control to the desired setting.
• There Is a protective time delay (up to 3 minutes) to prevent tripping of the compressor overload. For tills reason, the unit may not start normal heating or cooling for 3 minutes after it is turned back on.
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.
• Outdoor grille must have a minimum of 65% free area. Non-GE grilles may be t restrictive for proper performance. Consult your salesperson for assistance.
The temp control may not be set high enough.• 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 you need to allow time for the nxtm to cool down or warm up.
Outdoor air is entering the room.• Set the vent control to the CLOSE 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 fan switch may be set at 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 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.
Temperature display flashesThe compressor may have failed.• Set the mode control to STOP and then restart the unit. If the flashing light reappears within 30 minutes, call for service.

Most air conditioners are equipped with self-diagnosis system, which – if a fault occurs – gives signals by flashing special indicator or showing an error sign on the display. In such cases, look at the error code of your model. Look at the table below to learn about the main causes of the problems and ways how to solve them.

Gree GEHAA-D3DNA1CI air conditioner troubleshooting

PROBLEMCAUSES
Not runningCheck if electrical wire is damaged and if breaker switch is on. Check if the power supply is correct.
Check if the timer switch is on or not.
The air conditioner runs but does not cool enoughCheck if the preset temperature is too high.
Check if sunlight is shining directly into the room. Check if the doors and windows are open.
Check if there is anything obstructing the air discharge. Check if the exhaust fan is working.
Check if the air filter is dirty or clogged.
Vapour or mist coming out of the unit while running.Hot air in the room mixes with cool air. This causes mist.
Remote control not workingLoose or disconnected wire between the unit and the display. Check if the batteries are inserted in correct direction.
Check if the batteries are empty.

Gree GWH09AB-A3DNA1B air conditioner troubleshooting

PROBLEMCAUSE/SOLUTION
Air conditioner does not restart.Cause: The evo system has a built in 3 minute delay to prevent short and/or rapid cycling of the compressor.
Solution: Wait 3 minutes for the protection delay to expire.
Air conditioner emits unpleasant odor when started. Cause: Typically unpleasant odors are the result of mold or mildew forming on the coil surfaces or air filter.
Solution: Wash indoor air filter in warm water with mild cleaner. If odors persist, contact a qualified service professional to clean the coil surfaces.
You hear a “water fl owing” sound.Cause: It is normal for the air conditioning system to make “water flowing” or “Gurgling” sounds from refrigerant pressures equalizing when the compressor starts and stops.
Solution: The noises should discontinue as the refrigerant system equalizes after 2 or 3 minutes.
A thin fog or vapor coming out of the unit when air conditioner is running.Cause: It is normal for the air conditioning system to emit a slight fog or water vapor when cooling extremely humid warm air.
Solution: The fog or water vapor will disappear as the system cools and dehumidifies the room space.
You hear a slight cracking sound when the air conditioner stops or starts.Cause: It is normal for the air conditioning system to make "slight cracking” sounds from parts expanding and contracting during system starts and stops.
Solution: The noises should discontinue as temperatures equalizes after 2 or 3 minutes.
The unit will not runCause: There are a number of situations that will prevent the system from running.
Solution: Check for the following:
• Circuit Breaker is “tripped or turned Off’.
• Power Button of remote is not turned ON.
• Batteries in the remote control are low.
