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:

Overheating compressor

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.

Clunking sound

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.

  • Convenient Ways to Keep a Mercedes Benz 190D AC Condenser in Good Condition

    Your Mercedes Benz 190D's AC unit is comprised of several components that need to be serviced regularly in order for the cooling system to function properly. In fact, your car's AC condenser, a crucial part of the AC unit, needs to be flushed regularly to avoid overheating and blockage. Luckily, these defects are easily detected and addressed. So if you think your car's AC unit already needs to be serviced, then today is your lucky day. Here are some tips and tricks to go about a Mercedes Benz 190D AC condenser maintenance:


    Perform regular AC condenser flushing.


    Several AC components are not entirely built to last as long as your auto. In fact, there may come a time when the compressor might fail and cause several metallic parts to flow into the system. Eventually, these bits may accumulate in the condenser and impair efficient cooling. Luckily, you can help prevent this defect by performing regular flushing.


    Spray disinfectant cleaner on the AC intakes.


    Over time, when there is too much air and moisture allowed to enter the vehicle, molds and other odor-causing bacteria may multiply. You can address this problem by cleaning the interior of your auto. First, you'll have to vacuum the carpets and apply some protectant or cleaners to the vinyl surfaces inside the car. Once done, turn on your AC unit and make sure you set the blower at highest speed. Roll down the windows afterwards and begin spraying some disinfectant spray cleaner on the intakes of the system. To avoid inhaling the fumes, allow the spray to settle for several hours before using the auto.


    Check for refrigerant level.


    With the use of an AC pressure gauge, check if the refrigerant level of the system is at normal level. The gauge should show green if this is the case. However, if the gauge shows red, then this means that the level is low. You will need to refill refrigerant once in a while to keep the air coming out of the unit cool.


    Other maintenance tips

    When handling several AC components and liquids, always make sure that you wear protective gloves. You see, some AC fluids like the refrigerant are toxic and may cause several health hazards.
