Make Sure the Difficulty Isn? t the Furnace
Set your thermostat to AC mode and reduce the temperature placing. If the furnace fan kicks in, the problem isn? t in the particular furnace. If the enthusiast doesn? t manage, try resetting typically the furnace circuit breaker. If the lover still won? capital t start, call a pro? the fixes proven here won? t work.
Next, examine the outside condensing unit. The compressor (which sounds like the refrigerator) and supporter should be running. If not, the actual fine-tuning and repair processes shown here.
Caution: Turn Off the Power
Turn off the particular A/C and furnace breakers in the particular main electrical section before pulling the particular outdoor disconnect or even removing the distilling unit? s access panel. Then use a voltage tester around the wires coming into the contactor to be able to make sure the power is really off.
ALTERNATING CURRENT Doesn? t Work? Buy Parts
The particular AC contactor (relay) and start/run capacitor(s) (see illustration below) fail most generally and they are inexpensive. As a result it? s a new safe bet to acquire and install all those parts right apart, especially if your air conditioning service device is more aged than 5 years. The condenser fan motor can easily also fail, however it runs about $150? hold off getting that unless an individual? re sure that? s i9000 the culprit.
To purchase replacement parts, discover the nameplate upon the condensing product (not your furnace). Jot down the particular make, model and even serial number (or have a photo). Obtain the parts with an appliance retail outlet, furnace dealer or perhaps online.

Step 1
Learn the Anatomy of the Central Home Surroundings Conditioner
Central house air conditioner assistance systems consist involving two major elements: a condenser that sits outside your house and the evaporator coil (often referenced to as a good A-coil) that rests in the plenum of your furnace or air handler. The particular refrigerant inside the A-coil picks up heat from your house and moves that to the patio condensing unit. Typically the condensing unit supporter blows outside air flow through the condensing coil to remove the heat. The condensing unit homes the three pieces replaceable by a DIYer: the AIR CONDITIONING UNIT contactor, the start/run capacitor(s) along with the condenser fan motor. The particular condensing unit furthermore houses the air compressor, but merely a professional can replace that. The A-coil features no parts that may be serviced by the DIYer.

Test the particular Combines
Many remove blocks contain 2 cartridge fuses. Check them before a person proceed with repairs. A blown join is a sign of a faltering part inside the condensing unit. Therefore don? t merely replace it plus think you? ve solved the problem. Instead, replace the particular parts, install new fuses, and fire up the product. If it blows once again, call an expert? you? ve acquired more serious issues.
How to Take a look at Fuses In typically the Disconnect Block
Established your multimeter to the lowest Ohms scale and contact the red plus black leads in order to opposite ends of each fuse.
If you get the numerical reading, typically the fuse is fine.

Inspect the Inside involving the Access Section
Follow the electric conduit from the particular house? that? s where you? ll find the gain access to panel. With the power off, take out and store the access-panel retaining screws and remove the -panel. Before you change any parts, check out for rodents? nests or evidence of chew on wires plus electrical connectors.
If you find damaged wires or eaten insulation and can safely handle electrical repairs, discharge the particular capacitor first. After that repair the wiring and get rid of the particular nest. Otherwise, call up a pro.

Step 6
Replace the Start/Run Capacitor(s)
All atmosphere conditioning service products have one or more capacitor. The capacitor retailers electricity and lets out it during air compressor and condenser enthusiast startup to give equally motors an additional fix of power. In addition to it smooths away voltage fluctuations to safeguard the compressor and even condenser fan motor unit from damage.
Capacitors can degrade little by little, providing less new venture power over time. Or they can fail instantly. Steady capacitor failure could go unnoticed for a long period, stressing the compressor and condenser fan motor windings, resulting in their early malfunction. Since capacitors usually are cheap, it pays off to proactively exchange yours about every five years.
Just how to Replace the Capacitator
Have a photograph of the wires before disconnecting anything (you may require a reference after on).
Discharge typically the stored energy in the old capacitor.
Use needle-nose pliers to pluck a single wire at the same time by the old capacitor and snap it onto the corresponding tab of the new capacitor. The particular female crimp fittings should snap tightly onto the capacitor tabs.
Wiggle each connector to see if it? s tight. If this? t not, eliminate the connection and bend typically the rounded edges of it so it makes a tighter match within the tab.
Any time you? ve swapped all the cables, secure the new capacitor.
WARNING: Relieve the capacitor prior to disconnecting wires or perhaps removing it from its bracket.

Replace the AC Contactor
An AIR CONDITIONING UNIT contactor is the $25 mechanical relay that uses low voltage power from your temperature control system to switch 220-volt high-amperage current towards the compressor and condenser fan. AC providers can wear out and about and they are at typically the top of typically the list of typical air conditioning support failures. Even in the event that your AC contactor is working, that pays to replace it every a few years or so. Unscrew the old AIR CONDITIONING contactor before removing the wires. In that case move the wiring to the fresh unit.
Yank the connector off the old contactor plus move it to the same place on the fresh part.
Tighten the particular connectors where necessary.
Secure the brand new contactor within the condensing unit.
