Extreme care: Turn Off the ability
Turn off the particular A/C and air conditioner breakers in the particular main electrical screen before pulling the outdoor disconnect or perhaps removing the distilling unit? s obtain panel. Then utilize a voltage tester on the wires coming into the contactor in order to make sure the power is really off.
ALTERNATING CURRENT Doesn? t Operate? 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 safe bet to acquire and install individuals parts right away from, particularly if your weather conditioning service product is older than five years. The fondre fan motor can also fail, however it runs about $150? hold off getting that unless a person? re sure that? t the culprit.
To acquire replacement parts, locate the nameplate about the condensing product (not your furnace). Jot down the particular make, model and even serial number (or have a photo). Get the parts in an appliance retail outlet, furnace dealer or even online.

Test the Fuses
Many detach blocks contain a couple of cartridge fuses. Examine them before a person proceed with vehicle repairs. A blown join is an indication of an unable part inside typically the condensing unit. So don? t just replace it plus think you? ve solved the trouble. Instead, replace the particular parts, install brand new fuses, and fireplace up the device. If it blows once again, call a pro? you? ve obtained more serious issues.
How to Check out Fuses In the Disconnect Block
Arranged your multimeter in order to the lowest Ohms scale and contact the red and even black leads to opposite ends involving each fuse.
In case you get a numerical reading, the particular fuse is great.
