    A refrigerator has become a common household item these days and AC as well for town ares. A lot people don't familiar with the operation of these items and once a fault occurred they have to call a technician to rectify it. Technicians charge a lot to rectify even a simple thing as the owner doesn't know the subject. So I thought of discussing common faults which can be rectified your self without spending money or at least know your self what happened before technician checked.

    I am not a super qualified person in refrigeration field but I'll give my advices as I can.:cool:

    Please mention the Brand and model name if can. It will help me to find the solution

    Following can be happened

    1. Problem in blower - If the motor is running, problem may with the blower. If the fan bracket corroded the blower easily get damaged. So check whether there is any corrosion. You can pull the unit from back and remove the cover then check. (Remove the power supply first)

    2. Gas leak - It rarely happens in window type ACs.

    3. Block of heat exchangers - It will not happen suddenly as yours. Gradually the cooling effect reduces. So the unit should be serviced periodically.

    I have a question.:

    Fault: Our refrigerator draw more power than before. now it take around 2.5 units per day.
    before it was max 1.5 units.

    what will be problem ?

    checked:
    1. no door seal leak
    2. defrost timer/heater ok
    3. no cooling problems
    4. no air circulate problem

    is it compressor fault ?

    Followings could be a reason if the above are o.k

    1. Thermostat and it's setting - Check whether the position is same as earlier.

    2. Faulty compressor - Probability is less as if the compressor is faulty then it is cut off by over load protector. Please check the compressor is heating abnormally.

    3. Problem in heat exchanging - Keep enough space around the unit to exchange the heat through body condenser.

    Check the air is coming through outdoor heat exchanger. There is only one motor in window type AC. If the motor burnt then there should be no air flow. Normally plastic fans are damaged easily.

    It is easy to dismantle a Window type AC. You can check it your self. :cool:

    1. Thermostat and it's setting - it has digital thermostat (setting by button & led indicator) position is same.

    2. Faulty compressor - I have no idea is it over heating or not. never cut off overload protector. heat seems high but I don't know if it higher than normal operating temp. Is there temp range during running compressor ?

    4. it has enough space (around 8" from wall) dust free.

    Tell me the brand and model name. I'll try to find more technical details on this.
