Air Conditioner Doesn’t Cool Air Conditioner Doesn’t Turn On If your room or window air conditioner doesn’t cool or turn on, this expert guide to AC repairs will help. Most problems with window and room air conditioners can be categorized under one of two symptoms: they do not cool sufficiently or they do not turn on at all. Here is a closer look at how to troubleshoot and repair these issues. A window or room air conditioner that doesn’t cool may need to be recharged with refrigerant, but the chances are good it simply needs to be cleaned. You can do this yourself, which involves disassembling the unit, or you can call an air-conditioning professional. Before attempting the work yourself, consult your owner’s manual and make sure you have the right skills and tools to handle the task. Here is what a typical manual advises: 1Unplug the unit and carefully remove it from the window or wall. Put the air conditioner somewhere outdoors or in the garage where you can work on it.

2Remove the grille and filter and unscrew the metal case (taking care not to damage the coil’s fins).what is the best home ac unit to buy 3Wash the filter thoroughly or replace it with a new filter; how much does a whole house ac unit costmost filters are readily available at most appliance stores.window ac unit not in window 4Using a vacuum with a soft brush attachment, clean the coil’s fins. 5Spray water back through the fins from the fan side (protect the wiring and the motor with plastic). 6Clean the unit up with a rag, making sure all drains that allow condensed water to drip away from the unit are open. Allow it to dry thoroughly. 7Lubrication. While you have the unit apart, lubricate the motor according to your owner’s manual.

8Finally, reassemble and reinstall the unit. Window and room air conditioners draw a lot of electrical power, which can lead to less than peak performance or even complete failure. If your room air conditioner doesn’t turn on: 1Be sure the unit is plugged in and turned on. 2Check that the outlet works by plugging in a light that works (only for standard-voltage models—do not plug a light into a 220/240- volt receptacle). 3If the light doesn’t go on, the circuit has probably overloaded—check the electric panel or fuse box and reset the breaker or replace the fuse. 4If the light works, it’s likely that the air conditioner’s switch is faulty or the thermostat needs adjustment or repair. 5Be sure the thermostat is set to “cool” and below room temperature. 6Refer to the owner’s manual for thermostat repair. If repairing the thermostat doesn’t solve the problem, unplug the unit and call an air conditioner repair person.Danby 6000 BTU Window Air Conditioner

It is the simplest form of an air conditioning system and is mounted on windows or walls.

It is a single unit that is assembled in a casing where all the components are located. This refrigeration unit has a double shaft fan motor with fans mounted on both sides of the motor. One at the evaporator side and the other at the condenser side. The evaporator side is located facing the room for cooling of the space and the condenser side outdoor for heat rejection. There is an insulated partition separating this two sides within the same casing.The front panel is the one that is seen by the user from inside the room where it is installed and has a user interfaced control be it electronically or mechanically. Older unit usually are of mechanical control type with rotary knobs to control the temperature and fan speed of the air conditioner. The newer units come with electronic control system where the functions are controlled using remote control and touch panel with digital display.The front panel has adjustable horizontal and vertical(some models) louvers where the direction of air flow are adjustable to suit the comfort of the users.

The fresh intake of air called VENT (ventilation) is provided at the panel in the event that user would like to have a certain amount of fresh air from the outside.The indoor parts of a window air conditioner include: The outdoor side parts include:During operation, a thermostat is mounted on the return air of the unit. This temperature is used to control the on or off of the compressor. Once the room temperature has been achieved, the compressor cuts off. Usually, it has to be off for at least 3 minutes before turning on again to prevent it from being damaged. For mechanical control type, there is usually a caution to turn on the unit after the unit has turned off for at least 3 minutes. For electronic control, there is usually a timer to automatically control the cut-in and cut-out of compressor.The evaporator blower fan will suck the air from the room to be conditioned through the air filter and the cooling coil. Air that has been conditioned is then discharge to deliver the cool and dehumidified air back to the room.

This air mixes with the room air to bring down the temperature and humidity level of the room.The introduction of fresh air from outside the room is done through the damper which is then mixed with the return air from the room before passing it over the air filter and the cooling coil. The air filter which is mounted in front of the evaporator acts as a filter to keep the cooling coil clean to obtain good heat-transfer from the coil. Hence, regular washing and cleaning of the air filter is a good practice to ensure efficient operation of the air conditioner.Heat Pump Window Air ConditionerIn temperate countries, heating of the room is required. A heat pump window air conditioner unit is able to cool the room during summer and heat the room during winter. A reversing valve (also known as 4-Way-Valve) is used to accomplish this. During heating operation, it reverses the flow of the refrigerant which results in the evaporator to act as a condenser and the condenser as evaporator.
