Make Sure the Issue Isn? t the Furnace
Set your current thermostat to ALTERNATING CURRENT mode and reduce the temperature establishing. If the air conditioner fan kicks inside, the problem isn? t in the furnace. If the supporter doesn? t operate, try resetting the furnace circuit breaker. If the enthusiast still won? to start, call a professional? the fixes demonstrated here won? to work.
Next, examine the outside condensing unit. The compressor (which sounds like the refrigerator) and lover must be running. If not, stick to the troubleshooting and repair processes shown here.
Care: Turn Off the strength
Turn off the particular A/C and air conditioner breakers in the main electrical section before pulling the particular outdoor disconnect or perhaps removing the condensing unit? s access panel. Then make use of a voltage tester within the wires coming straight into the contactor to make sure the power is really off.
AIR CONDITIONING Doesn? t Function? Buy Parts
The particular AC contactor (relay) and start/run capacitor(s) (see illustration below) fail most usually and are inexpensive. Thus it? s a new safe bet to buy and install these parts right aside, especially when your weather conditioning service device is more aged than 5 years. The condenser fan motor may also fail, but it really runs about $150? hold off acquiring that unless you? re sure? t the culprit.
To purchase replacement parts, discover the nameplate about the condensing product (not your furnace). Jot down typically the make, model and serial number (or have a photo). Obtain the parts at an appliance shop, furnace dealer or even online.

Step 1
Learn the Anatomy of a new Central Home Atmosphere Conditioner
Central home air conditioner assistance systems consist of two major pieces: a condenser that will sits outside the house and the evaporator coil (often called to as the A-coil) that sits down within the plenum regarding your furnace or perhaps air handler. The refrigerant in the A-coil picks up the heat from your home and moves this to the patio condensing unit. Typically the condensing unit fan blows outside surroundings through the distilling coil to remove the heat. Typically the condensing unit homes the three parts replaceable by the DIYer: the AIR CONDITIONING contactor, the start/run capacitor(s) and the condenser fan motor. The condensing unit furthermore houses the air compressor, but only an expert can replace that. The A-coil features no parts that can be serviced by a new DIYer.

Step a few
Brush your Condenser Coils
It? s actually easy to clean the air conditioner condenser, and it? t one of many regular servicing tasks that will certainly extend the life span of your unit.
Target your garden nozzle upward into the top of the condenser coil to remove the crud buildup underneath the cover.
Work completely around the coil. And then aim the nozzle down and remove the debris over the coil fins.
Change the nozzle into a gentler stream and shoot water directly into the coils to be able to flush out any remaining debris.

Step four
Test the Fuses
Many disconnect blocks contain 2 cartridge fuses. Check them before a person proceed with fixes. A blown fuse is an indication of a failing part inside typically the condensing unit. So don? t just replace it and think you? ve solved the difficulty. Instead, replace typically the parts, install fresh fuses, and fire up the device. If it blows again, call a professional? you? ve received more serious issues.
How to Take a look at Fuses In the particular Disconnect Obstruct
Set your multimeter to be able to the lowest Ohms scale and contact the red plus black leads to opposite ends associated with each fuse.
In the event that you get a numerical reading, the particular fuse is good.
A zero, a minus symbol, or an infinity symbol (? ) shows a blown merge.

Step your five
Inspect the lining regarding the Access -panel
Follow the electric conduit from typically the house? that? s i9000 where you? ll find the access panel. With typically the power off, remove and store the access-panel retaining screws and remove the section. Before you change any parts, look at for rodents? nests or proof of eating on wires plus electrical connectors.
In case you find busted wires or wrecked insulation and may safely handle electric powered repairs, discharge the capacitor first. Then repair the wire connections and clean out typically the nest. Otherwise, phone a pro.
Tips on how to Discharge a Dual Start/Run Capacitor
Take away the capacitor from typically the retaining bracket.
After that touch an protected screwdriver between the particular HERM (or? H? ) terminal and even the COMMON (or? C? ) airport terminal.
Do the identical between the FAN (or? F? ) airport terminal as well as the? C? airport terminal.
On single-mode capacitors, simply make a limited between the a couple of terminals.

Step six
Replace the Start/Run Capacitor(s)
All atmosphere conditioning service devices have at least one capacitor. The capacitor retailers electricity and produces it during automotive compressor and condenser enthusiast startup to provide equally motors an additional jolt of power. Plus it smooths out and about voltage fluctuations to safeguard the compressor and even condenser fan engine from damage.
Capacitors can degrade gradually, providing less startup company power over period. Or they can fail right away. Continuous capacitor failure can go unnoticed for a long period, stressing the compressor and condenser buff motor windings, causing their early disappointment. Since capacitors are usually cheap, it makes sense to proactively substitute yours about just about every five years.
Exactly how to Replace a Capacitator
Have a photograph of the wire connections before disconnecting everything (you may need a reference afterwards on).
Discharge the stored energy inside the old capacitor.
Use needle-nose huge pliers to pluck one particular wire at any given time by the old capacitor and snap it onto the related tab of the new capacitor. The female crimp connectors should snap tightly onto the capacitor tabs.
Wiggle every single connector to notice if it? s i9000 tight. If it? h not, remove the plug and bend typically the rounded edges involving it so that constitutes a tighter match on the tab.
Whenever you? ve changed all the wire connections, secure the new capacitor.
WARNING: Release the capacitor prior to disconnecting wires or perhaps removing it through its bracket.

Step 7
Replace the AC Contactor
An AIR CONDITIONING contactor is the $25 mechanical exchange that uses low-voltage power from your temperature control system to switch 220-volt high-amperage current towards the compressor and fondre fan. AC contactors can wear out and therefore are at the particular top of the particular list of common air conditioning service failures. Even when your AC contactor is working, this pays to exchange it every a few years roughly. Unscrew the old ALTERNATING CURRENT contactor before eliminating the wires. Then move the wire connections to the new unit.
Yank some sort of connector off typically the old contactor in addition to move it in order to the same spot on the new part.
Tighten the particular connectors where necessary.
Secure the fresh contactor inside the condensing unit.
