Turn off the power at the switch.
Turn off the power at the outlet (if you are working on an ungrounded outlet).
If you have a thermostatic air conditioning system with a mechanical control, turn off both of its switches (one for each stage).

Check the wiring diagram

The wiring diagram for your air conditioner unit is a schematic representation of the electrical system for your air conditioner. It will help you to identify problems with your system and how to fix it. AC repair in North Branch MN

The wiring diagram only shows the general layout of how wires are connected, but it is important that you check this before attempting any repairs yourself. It’s important that you follow the instructions on how to read an electrical diagram as they vary from manufacturer to manufacturer, but they all generally include:

An arrow showing which way electricity flows through each circuit (5V at top; 0V at bottom)
Symbols representing switches and other components (switches have two terminals)

Check the terminals first

First, turn off the power to your unit. AC repair in North Branch MN
Next, check the terminals first. Make sure they’re securely attached and that none of them have become loose or disconnected. If you see any problems there, make sure to fix them before proceeding with other steps in this process.
Next, double-check your wiring diagram to ensure that everything is connected properly and safely before turning on again.

Measure the voltage at the outside unit

Measure the voltage at the outside unit. To do this, use a volt meter and check for three different voltages: between hot (red) wires and neutral (white) wires, ground (green) wires and neutral wires, and between hot and ground. If you’re coming up with a reading of less than 120 volts, it’s time to repair your air conditioner unit. AC repair in North Branch MN

Switch out if it’s faulty

If the fuse is blown, replace it with a new one. If the capacitor is faulty, replace it with a new one. If the relay that controls power to your unit has stopped working and needs to be replaced, do so by purchasing a compatible replacement part at your local hardware store.

Reinstall air conditioning unit

Disconnect the power supply to the air conditioner.
Remove the old compressor if necessary. You may need a helper or assistant with this step, as it can be heavy and awkward to maneuver by yourself.
Replace the compressor with a new one, making sure that all electrical connections are secure and wires are in place on terminals where they belong (most commonly black wires on one terminal, red wire on another terminal). Make sure your replacement compressor has come with wire connectors for easy attachment to existing wiring; if not, use pliers to crimp new connectors onto exposed ends of each wire before connecting them properly at both ends of your new unit’s wiring harnesses (again: black-red-black).
Check around all edges of your new AC unit for any leaks that might indicate faulty installation or poor quality materials; look especially under raised areas such as hoses or ductwork—these are common places where leaks occur when an installer isn’t careful! If you find any traces of moisture inside any part of your system after installing it properly then you should contact us immediately–we’ll send someone out right away so we can fix whatever went wrong! Don’t forget about checking underneath too—you never know what could happen over time…

Follow these steps in order to learn how to repair your air conditioning units.
