Guarantee the Problem Isn? t typically the Furnace
Set your thermostat to AIR CONDITIONING UNIT mode and reduce the temperature establishing. If the air conditioner fan kicks throughout, the problem isn? t in the furnace. When the enthusiast doesn? t manage, try resetting the particular furnace circuit breaker. If the fan still won? t start, call a professional? the fixes proven here won? to work.
Next, look into the outside condensing unit. The compressor (which sounds like some sort of refrigerator) and fan should be running. When not, the actual troubleshooting and repair processes shown here.
Care: Turn Off the ability
Turn off typically the A/C and air conditioner breakers in typically the main electrical panel before pulling the outdoor disconnect or removing the distilling unit? s access panel. Then make use of a voltage tester on the wires coming directly into the contactor to make sure the strength is really off.
ALTERNATING CURRENT Doesn? t Job? Buy Parts
The AC contactor (relay) and start/run capacitor(s) (see illustration below) fail most usually and they are inexpensive. As a result it? s a new safe bet to buy and install those parts right away from, particularly if your air conditioning service unit is over the age of 5 years. The fondre fan motor can easily also fail, but it runs about $150? hold off buying that unless an individual? re certain? s i9000 the culprit.
To acquire replacement parts, get the nameplate about the condensing device (not your furnace). Jot down typically the make, model and even serial number (or require a photo). Obtain the parts from an appliance retail outlet, furnace dealer or even online.

Step 1
Understand Anatomy of some sort of Central Home Atmosphere Conditioner
Central residence air conditioner service systems consist involving two major parts: a condenser that will sits outside your own house and the evaporator coil (often known to as a good A-coil) that is located in the plenum involving your furnace or perhaps air handler. The particular refrigerant within the A-coil picks up the heat from your residence and moves that to the outside condensing unit. The particular condensing unit fan blows outside air flow through the condensing coil to remove the heat. Typically the condensing unit properties the three components replaceable by some sort of DIYer: the AIR CONDITIONING UNIT contactor, the start/run capacitor(s) as well as the fondre fan motor. Typically the condensing unit likewise houses the automotive compressor, but just a pro can replace of which. The A-coil has got no parts which can be serviced by a DIYer.

Step 4
Test typically the Fuses
Many remove blocks contain two cartridge fuses. Examine them before an individual proceed with vehicle repairs. A blown join is a sign of a faltering part inside typically the condensing unit. And so don? t simply replace it and even think you? ve solved the trouble. Instead, replace the particular parts, install fresh fuses, and open fire up the product. Whether it blows once again, call a pro? you? ve got more serious concerns.
How to Check out Fuses In typically the Disconnect Obstruct
Arranged your multimeter in order to the lowest Ohms scale and feel the red and black leads to be able to opposite ends involving each fuse.
In the event that you get a numerical reading, the fuse is good.
A zero, a minus symbol, or an infinity mark (? ) shows a blown join.

Step your five
Inspect the Inside associated with the Access Section
Follow the electrical conduit from the particular house? that? s i9000 where you? lmost all find the accessibility panel. With typically the power off, get rid of and store the access-panel retaining screws in addition to remove the -panel. Before you replace any parts, check out for rodents? nests or proof of eating on wires and even electrical connectors.
When you find busted wires or eaten insulation and could safely handle power repairs, discharge the particular capacitor first. After that repair the wiring and clean out typically the nest. Otherwise, call up a pro.
The way to Discharge a Dual Start/Run Capacitor
Eliminate the capacitor from typically the retaining bracket.
Next touch an insulated screwdriver between the HERM (or? They would? ) terminal plus the COMMON (or? C? ) airport terminal.

Step 6
Replace the Start/Run Capacitor(s)
All air conditioning service models have no less than one capacitor. The capacitor stores electricity and launches it during compressor and condenser fan startup to give both motors an additional fix of power. Plus it smooths out and about voltage fluctuations to guard the compressor plus condenser fan engine from damage.
Capacitors can degrade slowly, providing less new venture power over period. Or they could fail in an instant. Progressive capacitor failure can go unnoticed for some time, stressing the compressor and condenser addict motor windings, resulting in their early failing. Since capacitors are cheap, it pays off to proactively substitute yours about each five years.
How to Replace a new Capacitator
Require an image of the wires before disconnecting anything at all (you may want a reference later on).
Discharge the particular stored energy throughout the old capacitor.
Use needle-nose pliers to pluck one wire at any given time by the old capacitor and snap this onto the matching tab of the particular new capacitor. The particular female crimp connectors should snap tightly onto the capacitor tabs.
Wiggle every single connector to discover if it? h tight. Whether it? h not, take away the connector and bend the particular rounded edges involving it so it the tighter fit in for the tab.
