Condenser cooling fan does not turn treatment

Release date:2017-11-06 Author: Click:

Condenser cooling fan can not rotate, the majority is due to the lack of lubrication of the sliding bearing shaft, bearing pad burning axles, or fan motor coil burnout due. It may also be due to the fan working time is too long, the current is large, refrigerator relay contacts poor work will be CCL blowout caused by the output circuit.

First, the sliding bearing shaft short of oil

In use, the condenser cooling fan does not rotate, you can first check with a multimeter fan motor coil is burned out. If the motor coil is in good condition, you can check whether there is oil at the bearing of the fan motor. If there is no oil, it indicates that the sliding bearing is lack of oil.

Second, lack of refrigerant

In use, it is found that when the freezer system has insufficient cooling capacity and is suspicious of lack of refrigerant in the refrigeration system, the manifold pressure gauge can be used to check the system pressure.

If the pressure on the high and low pressure side are low (high pressure below 83kpa, low pressure below 78kPa) at the same time there are bubbles in the liquid crystal glass, air outlet gas is not cold, which means that the lack of refrigerant system。

Remedy: Identify the cause of the leak, repair leaks, and replenish the system with refrigerant. The engine to ZO0r / mni run to the disappearance of the bubble when the pressure gauge reading low pressure side of about 118 a Z16kpa, high pressure side of about 1274 a 1596kpa.

Third, poor condenser cooling

Cooling system Condenser cooling is poor, mostly due to engine heat sink and condenser heat sink dust, debris blocked caused. Check, the manifold pressure gauge can be used to check the system pressure. If the high pressure gauge readings high at the same time, the engine heat sink and condenser heat sink is full of dust and debris, indicating that the condenser cooling is poor.

Approach: Eliminate accumulated in the engine heat sink and condenser heat sink at the dust and debris.
