contactor to the capacitor like the red one shown in figure 3. This wire is connected to the C _ terminal and will be left in place. The other unmarked terminal is the HERM terminal. For the remainder of this document, we will refer to the HERM terminal and C terminal for all types of capacitors. Figure 2 Figure 3
Problem: How do I wire up a dual round capacitor? • Arnold
Jun 06, 2012The capacitor wiring would not have anything to do with the unit not getting power unless the capacitor was wired in a way that would throw the circuit breaker because of a direct short to ground. I would like to suggest that you get a voltmeter, set the voltmeter to “Volts AC” and test between L1 and L2 on the contactor.
MAXRUN 45+5 MFD uf 370 or 440 Volt VAC Round Dual Run
The terminals are marked C (Common/Ground), Fan, and Herm (Compressor). Disconnect the capacitor from the AC unit. If you have a good multimeter you can check if the existing capacitor (or even the new one) is good or not. Use the uF setting and put the black lead on C, red lead on Herm. It should read 45 (for this capacitor anyway since it's a
Motor capacitor - Wikipedia
A motor capacitor, such as a start capacitor or run capacitor (including a dual run capacitor) is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. There are two common types of motor capacitors: run capacitors and start capacitors. Motor capacitors are used with air conditioners
What To Do When Your AC Unit Won’t Turn On | Mike Diamond
Jun 15, 2020NOTE: The Dual Run Capacitor may be located next to another capacitor. In that case, look for the capacitor labeled with “COM,” “FAN,” and “HERM” inputs. Dust off the upper component box with your duster. Check the wires for signs of damage while you’re at it. Unscrew the Dual Run Capacitor from its mount and remove it.
Problem: What to look for when a capacitor is bad? My unit
Jun 05, 2012Problem: What do I look for when a capacitor is bad?My Air Conditioner unit will not do anything! Answer: Capacitor problems are probably the second most common problem that I see every summer in our 28-year-old HVAC business!Air Conditioning and heat pump systems low on refrigerant charge are the most common problem that I see.

Nov 24, 2014The lower number is always going to be for the fan motor. Then the voltage 440 Volts AC. (The + -5 after the MFD is how much it the capacitor tolerance is rated to go up or down.) To order a replacement for this capacitor it would be 55+5 MFD (uf) and 440 volts AC Dual Run Capacitor. Example HVAC Dual Capacitor On Amazon
How to Wire Up a Start Capacitor | Hunker
Large electric motors with a high starting torque, like an air conditioner's compressor motor, often use a start capacitor kit. A start capacitor kit contains a start capacitor, relay and wires. The start capacitor gives the motor's windings an electric boost during the start-up phase.
How to Wire a Compressor, Fan Motor & Capacitor | Hunker
The compressor, fan motor and capacitor work together in an air-conditioning system's condensing unit. The wires feeding high-voltage electricity to the condensing unit connect to a contactor's line-voltage terminal and the air-conditioning system's low-voltage signal wires connect to the contactor's coil.
