What causes air circulation failure in Unique WS Air Conditioner?
Air circulation failure in your Unique Air Conditioner may be due to: 1. A clogged air filter. 2. Air shutters being closed. To address this, clean the air filter and open the air discharge shutters.
What causes Freezing Conditions at Evaporator Coil in Unique WS Air Conditioner?
Freezing conditions at the evaporator coil of your Unique Air Conditioner may occur due to: * Clogged air filter. * Faulty capacitor. * Faulty fan motor. * Air discharge shutters being too closed. * Lack of refrigerant. To address this, clean the filter, replace the capacitor, replace the fan motor, open the air discharge shutters, and check for leaks and add refrigerant.
Why is there no air supply at the indoor unit of my Unique WS Air Conditioner?
A lack of air supply at the indoor unit of your Unique Air Conditioner can be caused by: 1. The indoor fan motor being blocked or turning slowly. 2. The indoor fan motor capacitor being burnt. 3. The indoor fan motor winding being burnt. 4. Clogged air filters. To fix this, check the voltage and repair the wiring if necessary. Also, check if the indoor fan wheel is tight on the motor shaft and tighten if needed. Replace the indoor fan motor capacitor, replace the indoor fan motor, and clean the filters.
What to do if my Unique Air Conditioner only blows air but no cooling or heating?
If your Unique Air Conditioner's fan motor is working, but there is no cooling or heating, it could be due to: 1. The overload safety device on the compressor is cut out due to high temperature. 2. The compressor run capacitor is burnt. 3. The compressor winding is shorted. To address this, switch off the power and try again after one hour. Replace the compressor run capacitor, and replace the compressor if needed.
Why is the indoor fan not running at all in my Unique WS?
If the indoor fan is not running at all in your Unique Air Conditioner, it could be due to: 1. Failure in the motor capacitor. 2. No voltage out of the P.C.B. assembly for the fan motor. 3. Motor winding failure. To resolve this, replace the capacitor, replace the P.C.B. assembly, or replace the fan motor.
How to fix Communication failure between display and power units in Unique Air Conditioner?
To address a communication failure between the display and power units in your Unique Air Conditioner, check the communication cable. If the cable is faulty, replace it.
What to do if Evaporator coil sensor failure in Unique WS Air Conditioner?
If the evaporator coil sensor fails and the Unique Air Conditioner unit continues running, check the evaporator coil sensor and replace the sensor if it's faulty.
What to do if Return air sensor is short-circuited or disconnected in Unique WS Air Conditioner?
If the return air sensor is short-circuited or disconnected in your Unique Air Conditioner, check the return air temperature sensor and replace the sensor if it's faulty.
What causes Refrigerant flow failure in Unique WS?
Refrigerant flow failure in your Unique Air Conditioner can occur due to: 1. Refrigerant gas shortage. 2. Excessive overcharging of refrigerant. 3. Gas leakage. 4. Clogging of strainer or capillary tube. 5. A defective 4-Way valve. 6. A defective Solenoid 4-Way valve. 7. A defective compressor. To fix this, charge refrigerant gas, recharge gas, repair the leakage, replace the strainer, replace the 4-Way valve, replace the solenoid, and replace the compressor if needed.
Why does my Unique WS Air Conditioner only have the indoor fan motor working?
If only the indoor fan motor works on your Unique Air Conditioner, even when cooling or heating is desired, the cause may be: 1. The selected mode is on Fan Only, or on Cool when heating is desired. 2. The temperature is set to a value that is too high (in Cool mode). 3. A faulty compressor. To solve this, check if the room thermostat is on the desired mode and select the correct mode. Observe the temperature setting on the room thermostat. If the compressor is faulty, replace it.
