Question about Heating & Cooling
Unit is not cooling. It is taking in air in the return air, but not putting any out. Unit is also loose up top and making loud noises. rubber washers were worn out. I thought somthing was caught in the fan, but it was just a loose motor. I tightened the bolts up, but it still makes loud noises. What should i do about the unit not cooling, and what should i do about the rattle?
Every air conditioner has a motor called 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 unit should function normally. If the compressor doesn't start when the overload resets, the overload will again cut the electricity to the compressor. This cycle will continue indefinitely. (Always allow three to five minutes before restarting the compressor.) If this situation is occurring, unplug the air conditioner and get help from a qualified repair technician. This problem is often fatal to the air conditioner because the cost of repair often exceeds the price of a new air conditioner...
hope this will give u a clear idea..
