Refrigerator compressor running for about a few seconds, overheating, protection, power failure, has been repeated
Pipe blockage, high pressure, compressor protection
According to what you said, here is a little experience in my actual maintenance, which can be referred to and analyzed by you. The possibility of dirty plug is very large in case the compressor is excluded. Because after fouling current becomes large, and the ice blocking current decreases (your reference rated current on the compressor with the current meter test shows that fouling occurred in the capillary) and dry filter junction, ice blockage occurred in the capillary tube (evaporator) and low junction. By that fouling appeared in the condition of high pressure, when the pressure of the compressor after you stop and recoil to block the high-pressure area objects in the low pressure area pressure rises out, such as compressor start for a period of time, the system will have the refrigeration state, and then with the high pressure area pressure becomes larger dirty, and blocked the system, current increase caused by overheating of the compressor self protection, repeated start stop.
1. Suction pressure is too low2. Condensation pressure is too high3, the compression ratio is too highThe causes of low inspiratory pressure usually include pressure switch setting errors, suction tube pressure drops, low work load, and restricted evaporator coils.The cause of condensation high pressure exhaust pipe condenser including insufficient air flow, or the condenser size is too small, filling in refrigerant system or non condensed matter too much, the compression ratio by ultra low suction pressure and condensing pressure high enough into the compressor, such as within the prescribed scope of work, this situation is not caused by fault.It is recommended to monitor the temperature of the exhaust pipe to determine whether the compressor is overheated and the exhaust pipe temperature is less than 250` (107.2`c). In this case, the service life of the compressor will not be shortened.
