Mercedes Benz 190D Ac Condenser
Common Culprits behind a Faulty Mercedes Benz 190D AC Condenser
Driving the Mercedes Benz 190D on a hot summer day is made more comfortable and convenient with a working AC unit. But often times, car owners neglect to perform regular flushing and maintenance on the AC components. If this is continued, several parts like the AC condenser may start to malfunction. Without an efficient AC condenser, the whole cooling unit may break down. In fact, the compressor may start to produce an irritating clunking noise. So if these signs and symptoms are present in the auto, better perform some troubleshooting. Here are some common faults encountered with a Mercedes Benz 190D AC condenser and the reasons behind them:
An overheating AC compressor is usually a result of a clogged or dirty AC condenser. Failure to flush the condenser may lead to the part's clogging, which in turn, may restrict the passage of oil to compressor. Eventually, the lack of compressor lubrication will cause the component to overheat, and at some point, it would probably shut off. To avoid this AC problem, allot enough time flush the condenser.
Contamination in the AC condenser may also lead to a noticeable clunking sound in the compressor. The sludge build-up or dirt contamination in the condenser will contribute to a lower than normal pressure system. And since most AC compressors have a built-in automatic shutoff feature when they detect an abnormally low pressure, they will turn on and off, causing the unusual clunking sound. Other times, the condenser is not at fault. When this happens, other components near the AC components like the evaporator, tubes, and valves may be checked.
Bits of metal in the condenser unit
If the AC unit is already old and not regularly maintained, then there may come time that the internal components may wear prematurely, causing several AC parts to break down. A common occurrence for aging parts is lack of lubrication. This happens when the Freon oil is insufficient, and as a result, it causes too much friction. Eventually, flakes of metal may travel to the condenser and may cause blockage to the flushing system.
