Wire Air Conditioner Contactor to Capacitor - air conditioner is condensation plant contains contactor and depending on the brand and model, one or two capacitors. Contactors, the high voltage relay switches with a low voltage coil, capacitor unit on and off. Capacitor holds voltage of compressor and fan motor circuit; These engines have dead spots in its coils, for the capacitor modules. units connected to a capacitor using double condenser, which contain two capacitors in a single housing condensation. The capacitor receives its power even if wire unit combines common contactor terminal to condense.
How to Wire Air Conditioner Contactor to Capacitor
Turn off condensing unit's electrical disconnect switch. If unit has disconnect box mounted to wall, then open box and either flip switch to off position or pull out bus bar. If unit wires directly to circuit breaker, then turn off circuit breaker that has Air Conditioner or Heat Pump identification label. Often, main electrical panel, found next to electric meter, holds condensing unit's circuit breaker.
Remove condensing unit's cover. Begin by removing screws holding condensing unit's electrical service box's cover. Use correct type of screwdriver, usually 1/4- or 5/16-inch hex-head screwdriver. Pull cover off of condensing unit. wires from electrical disconnect enter condenser under service box.
Examine contactor. two wires from disconnect switch attach to one end of contactor, and wires leading to condenser's electrical parts connect to other end; low-voltage wires attach coil, located on bottom of contactor. wire, usually with red insulation, that connects to compressor's R terminal connects to contactor's L2 side.
Examine capacitor. Capacitors that operate single motor have two wire terminals. motor's capacitor wire connects to one of terminals. Dual capacitors have three wire terminals. letters on capacitor's lid identify terminals. Herm terminal connects to compressor's capacitor wire. fan's capacitor wire connects to Fan terminal. remaining terminal-- common terminal--has C or COM identification tag.
Cut section of 14-gauge insulated wire 8 inches long with pair of wire cutters.
