So follow the users guide, and if youve lost it already, request another copy of the same from the company. And to identify the fault better and faster, decide to fix your ac unit on a day that is relatively warm.
Be sane while you fix it. Cut off the power flow to the unit while you are at it. The cooling unit normally has a switch off panel for this. However, just in case you do not find any such panel, cut off the electricity to the whole home for that time. Also, rake away all debris from the condenser outside while you start the cleaning task.
The first step to detecting where the fault is is to take the grill cover off the condenser. Then, clean the blades or fins with a mild brush or some soft material, making sure to see that you do not damage the fragile fins in any way. After cleaning these, you have to dry them. Next, remove the screws and remove the grill-cover extremely carefully, because the fans stay connected to them, and you may inadvertently pull loose some wires. Then you have to hose out the fins, keeping the motor covered with some water-resistant material http://www.bjrefrigeration.com/ .
Since you have already dismantled your ac unit so much, you may as well lube the motor a little in this circumstance. Lastly, put back all the parts in their right locations, and you are done with a short and basic ac unit repairing effort.
Now, to see if youve actually set all of it right, turn the power on and let the equipment run for a while. Put your hands on the two pipes connected to the condenser. If one is warm and the other is cool, your unit is all right. However, if it isnt so, possibly you have to charge the refrigerant. And this cant be done alone. So call a professional.
If your cooling unit does not turn on automatically, you may have a look at the following actions. First, guarantee that the thermostat is set to cool, and is below the room temperature. Second, a blown-out fuse may also be the reason as much as a tripped breaker on the main panel. Third, keep the power switch on the furnace and the condenser switch on the outside turned on. 4th, but not least, guarantee that the 240-volt disconnect is not shut off. It is located just beside the outside compressor.
