Home air conditioning heating failure analysis and solution of 021 -56,102,546 
 A compressor in operation, but the air is not hot enough 
 a poor installation location. 
 (b) the outdoor temperature, indoor and outdoor temperature, the room heat up. 
 c refrigeration cycle system congestion. 
 d. refrigerant leak, the refrigeration cycle system can not play the normal heating function. 
 Second, the compressor starts immediately after the stop 
 (a) the installation location is not good airflow by blocking condenser (indoor side heat exchanger) ineffective, high discharge pressure and automatically shut down. 
 (b) the voltage is too low or too high, the compressor protection action. 
 c power supply capacity is not enough, the line pressure drop, compressor current is too large cause the compressor protector action. 
 (d) capacitor is bad or damaged, the compressor will not operate properly. 
 Third, in the heating conditions do not heating 
 A fan motor does not rotate 
 a plug is bad or the power cord and broken is the main fault, you must replace the power cord and check the plug. 
 (b) electrical connection is bad or thermostat failure, identify the reason for the repair or replacement of components. 
 (c) to touch the capacitor is bad or damaged and need repair. 
 d parts disconnected, the fan motor power failure, identify the reason for repair. 
 (e) the fan motor, check the fan leaves get stuck, the motor windings have been damaged, if damaged, should be replaced. Four, the outdoor fan motor can be rotated, but the compressor does not 
 a voltage is too low or too high, the current large result in compressor protection action. 
 (b) the power capacity is too small, the pressure drop, compressor protected and downtime. 
 c electrical wiring problem, the compressor can not operate. 
 (d) failure of the compressor itself, the need to replace the compressor. 
 2 compressor can work, but no hot air 
 a refrigeration cycle system for leaks. 
 (b) refrigeration cycle blockage. 
 c. compressor valve leakage, or bad, although the operation was not compressed gases. 
 (d) the failure of four-way valve, no change, check the line or replace the four-way valve.
