iii.Whistling sounds indicate the release of high-pressure gas from a crack in the pressure tube inside the compressor.

iv.Clucking sounds indicate that the suspended spring inside the compressor has broken

v.Knocking sounds from inside the compressor indicates that a large quantity of moist refrigerant vapor or refrigerating oil has linked into the compressor cylinder.

vi.Striking sounds from metal parts inside the compressor indicate that moving parts are loose.

b)Listen to the gas flowing in the evaporator by opening the refrigerator door while the compressor is in operation. Normally, refrigerant circulating in the evaporator produces a gentle whistling accompanied by a sound similar to water flowing. If only the whistling can be heard and there is no sound similar to water flowing, then the refrigerant has already percolated. If neither sound can be heard, the filter or capillary is clogged.

Touch and Feel

a)Feel the compressor while it is running. Its temperature should be less than 194ºF. Its temperature may exceed 194ºF if it has been running for an extended period.

b)After the compressor has operated for 5~10 minutes, feel the condenser. The temperature of its upper part should be higher than that of its lower part (or its right part is hotter than its left part, depending on the type of condenser coil). This indicates that the refrigerant is circulating properly. If the condenser is not hot, then the refrigerant is leaking. If the condenser is hot for only a few minutes and then cools down, the filter and capillary are clogged. If hot air is blown out of the forced air-cooling condenser, the system is out of order.

c)Feel the filter’s temperature. Normally, the temperature on the filter’s surface should be a little higher than the ambient temperature. If the filter is lower than the ambient temperature, then the meshes of its screen are clogged. This obstructs the flow of refrigerant and causing a drop in temperature due to throttling.

d)Feel the temperature of exhaust gas from the refrigerating system. The exhaust gas should be extremely hot. If the refrigerator has an enclosed compressor refrigerating system, there should be no frost or condensation on the gas suction tube. However, frost and condensation may appear for a very short time period when immediately after starting the machine.

Do not use only one of the indicators from the checklist above to decipher the state of your refrigerating system. It is advisable to find out two or more abnormal phenomenon, or conduct comprehensive troubleshooting because several kinds of troubles may share a common abnormality.
