35. Next, look into the outside condensing device. The compressor (which sounds like the refrigerator) and lover ought to be running. If not, stick to the servicing and repair methods shown here.
36.  
37.  
38. Extreme caution: Turn Off the strength
39. Turn off typically the A/C and air conditioner breakers in typically the main electrical panel before pulling typically the outdoor disconnect or perhaps removing the condensing unit? s obtain panel. Then work with a voltage tester on the wires coming in to the contactor to be able to make sure the power is really off.
40.  
41. AIR CONDITIONING Doesn? t Job? Buy Parts
42. Typically the AC contactor (relay) and start/run capacitor(s) (see illustration below) fail most often and they are inexpensive. So it? s a new safe bet to acquire and install these parts right apart, especially when your air conditioning service unit is more aged than five years. The fondre fan motor can also fail, but it really runs about $150? hold off buying that unless a person? re sure that? s the culprit.
43.  
44. To buy replacement parts, discover the nameplate on the condensing device (not your furnace). Jot down the make, model and even serial number (or have a photo). Get the parts at an appliance retail store, furnace dealer or even online.

61. The Anatomy of a new Central Home Atmosphere Conditioner
62. Central house air conditioner support systems consist of two major components: a condenser that sits outside your current house along with the evaporator coil (often known to as a great A-coil) that sits inside the plenum of your furnace or even air handler. The refrigerant inside the A-coil picks up heat from your home and moves it to the backyard condensing unit. The particular condensing unit lover blows outside air through the condensing coil to eliminate the heat. The condensing unit homes the three elements replaceable by the DIYer: the AC contactor, the start/run capacitor(s) along with the fondre fan motor. The particular condensing unit in addition houses the compressor, but just a pro can replace of which. The A-coil features no parts that could be serviced by the DIYer.

118. Replace the Start/Run Capacitor(s)
119. All air conditioning service devices have one or more capacitor. The capacitor shops electricity and lets out it during converter and condenser supporter startup to give the two motors another fix of power. And even it smooths away voltage fluctuations to safeguard the compressor and even condenser fan motor from damage.
120.  
121. Capacitors can degrade gradually, providing less startup company power over period. Or they could fail right away. Continuous capacitor failure could go unnoticed for years, stressing the automotive compressor and condenser buff motor windings, leading to their early malfunction. Since capacitors usually are cheap, it makes sense to proactively substitute yours about every single five years.
122.  
123. How to Replace the Capacitator
124. Have a photograph of the wiring before disconnecting everything (you may will need a reference afterwards on).
125. Discharge the particular stored energy inside the old capacitor.
126. Use needle-nose pliers to pluck one particular wire at any given time by the old capacitor and snap it onto the related tab of the particular new capacitor. The particular female crimp fittings should snap tightly onto the capacitor tabs.
127. Wiggle each connector to observe if it? s i9000 tight. If it? s i9000 not, eliminate the connector and bend typically the rounded edges of it so this makes a tighter fit in on the tab.
128. Whenever you? ve changed out all the wiring, secure the brand new capacitor.
129. WARNING: Discharge the capacitor just before disconnecting wires or perhaps removing it coming from its bracket.

139. Replace the ALTERNATING CURRENT Contactor
140. An ALTERNATING CURRENT contactor is a new $25 mechanical pass on that uses low-voltage power in the thermostat to switch 220-volt high-amperage current for the compressor and condenser fan. AC providers can wear out there and they are at typically the top of the list of popular air conditioning service failures. Even in the event that your AC contactor is working, this pays to exchange it every a few years approximately. Unscrew the old AIR CONDITIONING contactor before taking away the wires. Then move the wire connections to the fresh unit.
141.  
142. Yank a new connector off the old contactor and move it in order to the same place on the fresh part.
143. Tighten the connectors where needed.
