Air-Conditioner doesn’t start at all Check to see if a power is fed to the air conditioner. Is it 220-240volt range? If there’s no power, check the fuses or circuit breakers. If there’s still no power at this power point, you will need to contact a qualified electrician to restore power to the outlet. If there is power to the air-conditioner but it is still completely dead there may be a problem in one or more of the following areas: House & appliance Wiring (Inspect for any broken or burnt wiring), Thermostat, Compressor, Overload and/or relay, Selector switch, Electronic Controller
The fan runs but there cold air isn’t coming out Is the air-conditioner otherwise not working?
Is the thermostat knob turned to the proper setting or cold setting on electronic controller? Is the compressor motor running? The compressor may not be seen. It is located inside the air-conditioner at the center. Is it humming or making any kind of continuous noise or causing the lights to dim? If it is making a continuous noise, and your air-conditioner is still not cooling, there may be a problem with one or more of the parts like Compressor, Condenser or Evaporator
If the compressor is not running but you do have power to the air-conditioner there may be a problem in one or more of the parts like Compressor, Overload and/or relay, Thermostat (Open thermostat), Burnt wiring, Bad selector switch, Capacitor or Electronic controller. These parts are not user serviceable and If you need more assistance, please contact an authorized service provider. The air is cool but doesn’t seem to be adequately cold If the air doesn’t seem to be adequately cool it is necessary to use a thermometer to check the difference in temperature between the supply air going away from the air-conditioner and the air being returned from the room.
Normally, the temperature difference should be more than 10(C. For example, if the temperature going into the air conditioner is 26(C, the temperature coming out of the air-conditioner should be at least 16(C or less. If the difference is 12( or more there is probably no cause for concern. If the temperature difference is less than 10( you should check:
Air Ventilation Check to make sure the air ventilation is closed. If it’s open, it will bring in outside air and reduce the efficiency of the unit.
Condensing coils The condensing coils will always be on the “warm” side of the air-conditioner. That is, on the side that faces outside of the room to be cooled. Air is drawn into the back of the air conditioner on the sides through vent slots and is blown directly out through the condenser coils. If the coils get clogged with lint, dust and dirt the cooling system cannot provide the cooling necessary. To clean the coils it will be necessary to remove the entire cover of the air conditioner or pull it out of the wall to gain access to the coils. They can be cleaned by blowing compressed air at them or by using a soft bristle brush to wipe the dirt off.
It is important to also clean any dirt or lint build-up in the bottom of the air conditioner so the condensing fan slinger will pick up the condensate water properly. Little water dropping around inside room All window air-conditioners remove moisture from the air if there is, any. The window air-conditioners collect this moisture in the drain tray of the air-conditioner placed at the bottom and attempt to evaporate the moisture.
The evaporation process: Initially, the water drips down from the cold evaporator coils on the front of the air-conditioner. Then the water collects in the bottom of the air-conditioner base, the “pan.” If the air conditioner is installed properly it will be tilted slightly back. The water then collects near the back of the unit. The fan blade used to cool the rear condensing coils have a rim on the outside of the fins of the blade, called “slinger,” will come close to touching the inside of the drain pan when the fan is rotating. As the water collects in the pan and reaches the depth necessary for the fan ring to touch it, the ring will lift the water up, partly and the fan will splash it over the condensing coils. Because the coils are warm, they will evaporate the moisture to the outside.
While this is happening it is normal to hear water splashing and sloshing around. As long as there is no water leaking inside the room that is being cooled there is no cause for concern.
Do not drill into the bottom of and air-conditioner to “let the water out.” The air-conditioner tries to start for a few seconds and then stops Every air conditioner has a motor inside a compressor. The compressor provides the cooling capacity for the air conditioner. If the compressor or its electrical controls are defective the compressor may try to start, fail, and create an electrical overload. If the unit does create an overload, every compressor circuit is also equipped with an overload safety switch. The safety switch is designed to protect the compressor from burning out. The safety switch will cut the power to the compressor for a certain length of time and then reset itself.
When it resets it will allow the electricity to flow to the compressor once again. If the compressor then starts, the air-conditioner should function normally. If the compressor doesn’t start when the overload resets, the overload will again cut the power to the compressor. This cyclic event will continue indefinitely. (Always allow three to five minutes before restarting the compressor.) If this situation is happening, unplug the air-conditioner and get help from a qualified appliance repair technician to repair the air-conditioner at the SmartCare center. This problem is often fatal to the air conditioner because the cost of repair often high.
A motor is running but there is no air blowing Every air-conditioner is equipped with minimum two motors, the compressor-motor and the fan motor. It is possible for the fan motor to be defective and the compressor to be running. In this case the air-conditioner will come out to be running and may even sound “normal” but no air is blowing out the front or back of the unit. If, after removing the grill and other metallic parts of the air-conditioner you observe the fan blade is jammed / very rigid; difficult to rotate, the fan motor need to be replaced. If the fan blade turns freely the wiring/harness of the fan motor will need attention.
It will be better to call a qualified technician to find-out the cause of the problem, which could be with either the capacitor or the selector switch or the motor itself. The air-conditioner vibrates when it cuts off The compressor in all window air conditioners has a powerful motor. When it starts up and shuts off – the whole air conditioner can vibrate/shake, sometimes little loudly. Usually there is nothing wrong but it is possible that the compressor mounting bushes are worn out or missing; calling for replacement. If that is the case the mountings can sometimes be replaced.
Be sure that the air conditioner is securely mounted in the window frame if the air-conditioner vibrates/shakes. Water leaks out the front grill of the air-conditioner It is normal for water to collect in the lower base of an air conditioner. See the note under: ” Little water dropping around inside room.” If water leaks out the front it is usually because the unit is tilted forward in the window frame. All air conditioners should be installed carefully to ensure that they tilt slightly back to allow for proper removal of the condensate. The air smells stale Air conditioners remove moisture from the air. The water collects in the base of the unit. Under normal conditions this water will be evaporated out of the unit. However, it is possible for some water to sit stagnant in the base of the air conditioner for extended periods of time. There is no easy way to prevent this problem.
The problem will be reduced if you carefully clean the base of the inside of the air conditioner at least once a year. That will keep any dirt, lint or dust from absorbing the water and allowing mold and mildew to grow. Also, replace the filter behind or in the front cover. Can I run my air conditioner through out the year? You can run the air conditioner as long as both the outside and inside temperatures are above 16(C. If either of the temperatures is too cold, the air-conditioner may not function properly. What capacity of air conditioner do I require? The capacity of air-conditioner depends on volume of each room to be cooled and its heatload.
The cooling capacity of an air conditioner is measured in kilo Calories kCal/hr or British Thermal Units (BTU/hr). If you purchase an air conditioner that is too small for the room it will not cool adequately, also if you buy the one that is too large, the air conditioner will cool the room before it dehumidifies that may give you feeling of sweaty. So, get this calculated before purchasing the air-conditioner. May I know what is EER? The EER, an abbreviation of Energy-Efficiency Ratio, measures the air conditioner’s energy consumption and efficiency. It is a ratio of thermal energy to electrical energy.
A high EER ratio means less electrical energy is being consumed that further means more money savings. How often should I clean the air-filter? You should keep the air-filter clean so that maximum cooling capacity and efficiency is ensured. During peak usage times the filter should be inspected once a week to make sure that it is not clogged with dust, fiber etc.. Can my air conditioner be installed into a wall? And do I need to call any installation team? Normally the room air-conditioners are of two types – Window and Split. Select models of the Godrej air-conditioners are of window type which can be installed in a wall with the necessary frame etc. after making necessary opening into a wall. They by name itself can be installed in the windows. It is better to get the air-conditioner installed through the authorized service provider/installer.
How long do new air conditioners typically last? The life expectancy of a window & split type air-conditioners vary from installation to installation and depends upon many aspects. However, it is approximately 8-10 years. What do I have to do for maintenance? Proper preventive maintenance saves money by ensuring efficient operation and avoiding premature failure of parts. Inspect, clean and replace air-filters regularly. Get the air-conditioners serviced regularly through authorized service providers – Godrej SmartCare. If the air-conditioner has completed its warranty period, then it will be better to enter into the service contract.
What is COP?
Coefficient of Performance, is the ratio of the power input and power output. For example a modern air-conditioner will provide 3kw of cooling for 1kw of electrical power input. Therefore the COP is expressed as 3. Do refrigerants harm the ozone layer? Yes, some do while others do not. Normally all refrigerants handled by reputed manufacturers and its service technicians will never be released to the atmosphere that could deplete the ozone layer. It is important to note that refrigerants alone are not responsible as many other chemicals cause global warming problems apart from Ozone depletion.
Burning of fossil fuels causes problems on larger scale. Explain the difference between air-conditioning and comfort cooling? Air-conditioning covers many factors like cooling, heating, ventilation, air filtration, air circulation and control over humidity. Comfort cooling mainly relates to provision of just cooling to improve comfort. My unit won’t turn on, or off, consistently when I press the remote button, or when I change the temperature? First, check the batteries of the remote controller. Even if the screen is visible but faded the batteries may be compromising system operation. Good alkaline AAA batteries (2 nos) are required for the unit to function properly.
We recommend you DO NOT use rechargeable batteries, standard, or low priced bulk buy batteries in I-Sense remotes. Batteries should be changed at least once every six months even if the appliance is not used, or when the display fades if less than six months.
Secondly, check that the remote is in a direction that the I-Sense infrared link can communicate with the indoor unit, till the time air-conditioner is running. If not, then move it to a position where it can and press appropriate button on remote controller. When the indoor unit beeps each time you press a button on the remote, then it is in a good condition. The system WILL NOT function properly as expected if the remote is in a drawer/ cupboard, under an object or in between cushions on a sofa set etc.
The Air Conditioner sometimes switches itself off even though it hasn’t reached the set temperature and then won’t start up again? Check that the remote is in a position that the infrared link can communicate with the indoor unit. If not then move it to a position where it can. When the indoor unit beeps each time you press a button on the remote, then it is in a good condition. Check the batteries – good quality batteries are required for the unit to function properly. The temperature on the remote shows a lower temperature than the one I have set on the remote, but the air-conditioner stops heating or cooling The display on the remote could be inaccurate as it is only indicative. This will not harm the performance of the system; it means you need to use the remote as an indication only. If the room feels cold when you’re heating increase the temperature a degree or two, and wait 5-10 minutes for the air-conditioner to raise the temperature. Repeat the exercise until room temperature is in a comfortable zone. NOTE: The remote may indicate a 2°C variation.
