A system has many components that are split between an inside and outside setup. Together with the bigger items, such as the evaporator coils, the system also requires a way to power its everyday functions through using a transformer. This tiny black box extends the incoming high voltage to low voltage so that the system can operate effectively and safely; however, the transformer might need to be replaced after some time. Attention is required by reinstalling a transformer to wiring detail for the ideal setup process.
Shut off all electric power to the air-conditioning unit by removing any power wires from their electrical outlets. Additional upkeep can be practiced by shutting off the circuit breaker that provides the unit’s electricity. Confirm that the air-conditioning unit isn’t receiving power by applying a non-contact circuit tester to the hard-wired leads.
De-solder the old transformer’s cable leads using a soldering iron from the unit’s leads. Permit the air-conditioner’s contributes.
Unscrew the transformer. Place the transformer.
Place the transformer in the same place since the transformer on the air-conditioner unit. Secure the transformer to the region with screws and a screwdriver. Be certain to tighten the link securely without pinching the loose wires hanging in the device.
Strip a quarter-inch of insulation from four loose transformer cables using a wire stripper.
Connect the black cable from the transformer to the air unit’s loose black cable in the previous transformer installation by bending together the exposed cables.
Repeat step 4 to the wires that are white, red, and orange transformer. Each colour should match the wires extending out of the air unit.
Solder all four relations with solder and a soldering iron. Wrap each link with electrical tape to cover wiring and the exposed pipes.
Connect the transformer’s yellow cable to the yellow secondary lead screw onto the air unit by wrap the exposed cable end around the screw.
Repeat step 7 to the blue wire on the adjacent secondary guide screw.
Remove in the region and return power to the unit. Test all functions.
