31.  
32. Why Is My Air Conditioner Not Cooling the House?
33. Guarantee the Difficulty Isn? t typically the Furnace
34. Set your own thermostat to AIR CONDITIONING UNIT mode and decrease the temperature environment. If the air conditioner fan kicks in, the problem isn? t in the particular furnace. When the supporter doesn? t work, try resetting the particular furnace circuit breaker. If the lover still won? t start, call a professional? the fixes displayed here won? capital t work.
35.  
36. Next, look into the outside condensing product. The compressor (which sounds like a new refrigerator) and supporter must be running. In the event that not, stick to the fine-tuning and repair processes shown here.
37.  
38. Extreme caution: Turn Off the ability
39. Turn off typically the A/C and furnace breakers in the main electrical screen before pulling typically the outdoor disconnect or perhaps removing the distilling unit? s obtain panel. Then utilize a voltage tester around the wires coming into the contactor to be able to make sure the power is really off.
40.  
41. AIR CONDITIONING Doesn? t Operate? Buy Parts
42. The AC contactor (relay) and start/run capacitor(s) (see illustration below) fail most usually and they are inexpensive. As a result it? s some sort of safe bet to buy and install those parts right away, particularly if your air conditioning service product is older than five years. The fondre fan motor may also fail, but it runs about $150? hold off buying that unless a person? re certain? s i9000 the culprit.
43.  
44. To buy replacement parts, discover the nameplate about the condensing device (not your furnace). Jot down the make, model plus serial number (or take a photo). Acquire the parts with an appliance store, furnace dealer or even online.

61. Understand Anatomy of a Central Home Atmosphere Conditioner
62. Central house air conditioner services systems consist of two major components: a condenser that sits outside your current house plus the evaporator coil (often called to as an A-coil) that is located within the plenum of your furnace or perhaps air handler. The refrigerant within the A-coil picks up the heat from your residence and moves this to the backyard condensing unit. The particular condensing unit fan blows outside air through the distilling coil to take out the heat. The condensing unit residences the three parts replaceable by the DIYer: the ALTERNATING CURRENT contactor, the start/run capacitor(s) as well as the condenser fan motor. The particular condensing unit in addition houses the converter, but simply an expert can replace of which. The A-coil has no parts that could be serviced by a new DIYer.
