MORE ABOUT YOUR AIR CONDITIONER

One of the primary reasons why air conditioning units are so dependable is the hermetically sealed compressor. Motor and pump are enclosed within the sealed housing. A centrifugal starting switch such as the one used for washer motors wouldn't do here since you could not replace it if it should fail. Many units have a starting relay outside the compressor operated by voltage induced in the starting winding of the motor after the air conditioning compressor has approached normal running speed. Always install a replacement relay in exactly the same position as the old one (or in the position marked on the new relay). Not properly installed air conditioning relay can cause compressor failure. Most room air conditioners produced since 1960 use an oil-fill-in run capacitor to start the air conditioning compressor. This has two distinct advantages; it eliminates the relay, and it also greatly improves the power factor of the air conditioning compressor. This increased efficiency means that you gel mote cooling for less operating expense. Here's how air conditioning works: When an electrical motor tries to start, a large current flows through the windings. The capacitor is in series will start or in this case, the phase winding. As the rotor picks up speed, the current drops and a shift in the phase angle of the voltage occur This has much the same effect as actually changing the physical local tion of the winding, and it becomes in effect a running winding. Compressors for this type of operation are referred to as permanent split capacitor (PSC) compressors. They should not be operated under severe low-voltage conditions (where voltage drops over percent below rated voltage as their starting torque is greatly reduced and, in fact, may prevent them from starting at all. Low-voltage kils, consisting of a starting relay and starting capacitor, may be added in some cases, but the correct solution is to correct the low-vollamv condition itself. The capacitor is a storehouse for electricity. It must be discharged before handling or testing, in order to prevent dangerous electrical shock or damage to test instruments. You may have seen this done by shorting the terminals of a capacitor with a screwdriver. Don't do it most run capacitors now incorporate an internal fuse that can ho blown by shorting the charged capacitor. Get a 20,000-ohm 2-watt resistor (such as Allied's 45 c 608 to discharge the capacitor. Air conditioning resistor costs from 25 cents to 50 cents a replacement capacitor may cost $20 or more. Test the capacitor with the meter set on a high-resistance scale. The needle should sweep up and then drop back. Reversing the meter leads should produce the same effect. Apply your diagnostic skill here before you test. If the air conditioning capacitor is shorted, the air conditioning compressor will start when the thermostat is turned up, but since the phase winding continues to act start winding, the high current draw causes the overload protector to open within few seconds, and the compressor shuts down. An open capacitor would usually prevent the air conditioning compressor from running at all, and again the overload would shut it down, though not as quickly as in the case of a shorted capacitor. Often one of the terminals of a run capacitor will be marked with a dot, meaning that the internal connections of this terminal are closest to the metal housing. Always connect the wire from the start phase winding to the opposite terminal, as the higher voltage reduced in the start winding could conceivably damage the capacitor. Always test a capacitor for a ground with your meter. The overload protector is similar to that in an automatic-washer motor. It is a bimetal disk which opens the circuit to the compressor if there's overheating or excessive current draw. It is usually on top of the compressor housing. If it tests open under normal ambient temperatures it should be replaced. Replace capacitors and overload protectors only with components of the same value as the originals. Remember that everything you do to make your air conditioner operate more efficiently also reduces energy consumption. For the ultimate benefit, take it one step further—make a study of the conditions existing in your home and your living habits to see if modifications here will help. Adding additional insulation can aid you year around, as can storm windows and weather stripping. Be sure that vent fans above ranges and showers are being utilized.
