Thermostat Terminal Designations HVAC Wiring 101 Made Simple
When the thermostat calls for the air conditioner the contacts inside the thermostat close and Y gets the 24-volt power and passes it to the compressor contactor inside the condensing unit. This in turn, energizes the compressor and the condenser fan motor. The same thing happens for a heat with one other additional occurrence explained below.
Control Circuits for Air Conditioning and Heating | HVAC
Relays and Contactors. Relays and contactors are used in HVAC control circuits to turn things on and off such as blower motor, condenser fan motor or a compressor. Furthermore, contactors and relays work in much the same way in a typical HVAC control circuit. They are both normally controlled by 24 volts and they typically pass line voltage to a motor or compressor.

May 30, 2016Same thing here, I pullled off the wiring schematic and it only has one capacitor in the line, my condenser fan will start and run anywhere from 5 hours to two minutes, I think the capacitor is still good because it still cranks up the blower motor and the compressor, I’m gonna drop in a new blower motor tomorrow because it feels hot to touch and is making tha fried electric motor “hum
How to Wire an Outside AC Condenser | Hunker
Both are connected to the same contactor relay, located inside the condensing unit. One set of wires provides high-voltage 240-volt current that powers the fan and compressor unit, while the other set of wires are low-voltage wires that run from the thermostat and inside furnace unit to turn the outside condenser ON and OFF when needed.

How-To Wire Condenser Fan Motors Properly in 3-Wire & 4
May 24, 2018For a visual picture of typical wiring configurations, reference the following guide: HVAC Condenser Fan Motor Wiring Diagram. Finally, this guide is intended to be used as a general overview of common condenser unit wiring schematics. Some condenser fan motors wire to a circuit board while others use proprietary plugs for their connectors.
How To Troubleshoot HVAC/R Equipment
Nov 20, 2020Each side of the contactor coil will read 24v to ground with a multi meter on the volt setting. The broken common must be rectified before moving on. The compressor/condenser fan contactor pulls in and nothing happens, what's next. Ensure that the correct power is passing through the contactor to each load.
