TROUBLESHOOTING AND REPAIRS NORMAL REFRIGERATOR FUNCTIONS A domestic refrigerator is comprised of an electric control system and a refrigerating system. Since both systems work together, it is difficult to tell whether the refrigerating system is in good working condition. If any part of the refrigerating system or electric control does not work properly, the refrigerator’s efficiency will decline, operating properties will destabilize, and in worst cases, it will not function at all. - Page 17 During the entire service life of a refrigerator, the probability of problems occurring within a specific time is called its failure rate. A comparison between the control circuit system of a refrigerator and its refrigerating system indicates that the failure rate of the former is higher.
- Page 18 Knocking sounds from inside the compressor indicates that a large quantity of moist refrigerant vapor or refrigerating oil has leaked into the compressor cylinder. Striking sounds from metal parts inside the compressor indicate that moving parts are loose. Listen to the gas flowing in the evaporator by opening the refrigerator door while the compressor is in operation.
- Page 19 Analysis of Trouble The refrigerant leaks will result in an insufficient refrigerating capacity. This will lead to lower gas suction and exhaust pressure as well as hotter exhaust gas. The exhaust tube will become extremely hot, and the sound of gas flowing from outlet of the capillary will become louder than usual.
- Page 20 Analysis of Trouble Low efficiency of a refrigerating compressor refers to the actual reduction of gas discharge capacity and the corresponding reduction of refrigerating capacity under the condition that the refrigerant in the system is unchanged. This typically occurs when the compressor has been in use for a long time.
- Page 21 Remedy Purge the tubing. After replacing, the dry filter or cleaning it thoroughly, refill the system with refrigerant and seal the charging port. No Refrigerating “No refrigerating” refers to a situation where the compressor runs normally, but the refrigerator’s temperature does not decrease. While servicing, careful attention will be required to find and correct the cause.
- Page 22 3) Refrigerating system is clogged with dirt Analysis of Trouble Coarse-grained dirt and refrigerant oil in the system tend to settle and clog the capillary inlet. Flow of refrigerant stops when the filter screen is completely clogged by dirt. This condition has the same symptoms as when the refrigerating system is clogged by ice.
- Page 23 Loose frosting and poor refrigerating effect may occur if excessive refrigerant has been charged into the system. Excess refrigerant will occupy additional space in the evaporator. This will reduce its heat dissipating area, and the phenomenon of “liquid striking” may occur.
- Page 24 Abnormal thermal protection Analysis of Trouble The compressor current is within its normal range, but the thermal protector actuates repeatedly. Remedy Replace the thermal protector with a new one. Sudden stoppage due to other causes Normal Stoppage Thermostat generally controls start and stop of the compressor. When the temperature in the refrigerator reaches its desired value, the thermostat will shut down the compressor automatically.
- Page 25 Remedy Measure the voltage with a voltmeter; if it is really too low, give directions to the user for buying a stabilizer to step up the voltage, thus normal operation can be achieved. c) Check the thermal relay to see whether its contacts are closed. Analysis of Trouble The contacts of thermal relay sometimes may be open due to the leakage of temperature sensing agent from the temperature sensor.
- Page 26 Remedy Replace the old one with a new one. Check the terminals for loose connection and electric circuits for other abnormal phenomena. e) Mechanical faults of compressor i) Seizure of shaft This is normally caused by poor lubrication, insufficient quantity of lubricant, clogging in the lubricant oil’s line, or intermittent lubricant oil supply.
- Page 27 Analysis of Trouble Leakage of refrigerant and clogging in a refrigerating system will directly affect its refrigerating capacity. Due to the reduction in its refrigerating capacity, the refrigerator temperature cannot reach its rated value. The thermostat will not work, thus the compressor runs continuously.
- Page 28 grounding is perfect. If the grounding has no problem, turn off the refrigerator immediately, then check the insulation of electric circuits with a voltmeter. iii) Serious electric leakage Do not touch the case body of the refrigerator, its door handle or other metal parts with your hand.
