I can’t even figure out which wire would go to what! COM, connects to the Contactor and provides power to the Capacitor. I have a 40/5 uf 370 volt capacitor currently installed in my heat pump. You need to use a relay circuit when wiring in the hard start? so does the same concept apply to the compressor as well?

You will need a capacitor tester to test capacitors. A capacitor does not emit any odor, other than performing an electrical diagnosis the only indicators that it might be bad is swelling, extreme wear (rust/corrosion/etc.). Difficult to know how to fix when he did not just stick with OEM. What could cause this phenomenon? Compresser stays running but fan motor stops. I think air compressor will try start it but it can not start it since low uf on fan terminal of capacitor then maybe burnout winding at case start wire is connected to the Fan terminal of capacitor. resistor. Your email address will not be published. The capacitor delivers an initial energy burst to turn the system on when it’s time for a cooling cycle. Then purple wire from fan goes to other side of capacitor? Over the course of multiple centuries, the technology for capacitors has evolved in leaps and bounds, but the concept is basically the same. Does no one make them anymore? how does the start capacitor turn off, i never see anything in the schematics,, also, are those dual capacitors start capacitors ? How do I know compressor capacitance? Infiltration greatly affects your in door air quality. Hello, my Lennox air conditioner calls for a 60+7.5 capacitors. Thanks for the Ebay link. Showing 1 - 12 of 23 Could you explain to me what 440/370VAC/B means? Thus, need to know where to reconnect red wires to the start capacitor? Also, what will happen if I use the 60/5 440 capacitor? Unfortunately, the diagram on the inside panel is un-readable. But when I opened the A/C I noticed there was a wire not attached. The panel I remove to get to the capacitor is ZERO help because it shows an oval single run, and there’s only a space for a round dual run like the one I took out so when I wired it by the diagram on the panel of 2xOrange to fan, 1xBrown to Herm, and 1xPurple to common, the compressor no longer buzzes and the thermostat doesn’t “click” when switched to cool. Like the multimeters with capacitance setting, you would first have to remove the capacitor from the circuit and ensure it is discharged. Try Airstar supply for an exact original design spec capacitor. After these, disconnect the probes from the capacitors and repeat the process severally. After all these settings and placements, you can now check the readings on your multimeter. When they are separate they are simply called “Single” and when they are combined into one package they are called “Dual Round”. If your capacitor is operational, the value on the multimeter display should increase. :B IP44 S1 The only real issue you might run into is if it’s too large to physically fit into the location intended. Problem: The (Hard Start Capacitor) was removed and thrown away, so I can’t go wire to wire. It had been in my unit for 10 plus years. The AC capacitor is a component within the outdoor condensing unit of an air conditioner or heat pump. Have your fingers at a distance from the part that you will connect so that you don’t get shocked. He called into his office for something and came back to tell me that he would not be able to do a single thing more without my authorization because it turned out I only had a 5 year warranty and not a 10 year as I thought I had so I’d actually have to pay for the capacitor replacement… At $300 labor. :380v 50Hz 350w I prefer using alligator probes to discharge this type of capacitor. Killed the power and waited a few minutes. The common one should goto the Main contactor’s de-energized side. If your not sure trace the wires, common always goes with common. There was a red and purple wire attached to one terminal, a red wire to another terminal, and an orange wire attached to the third. Get it as soon as Mon, Jan 18. The one labeled C is the common wires for both. It appears to be connected to the compressor. Thanks! Take a pair of pliers and press them on the leads of the capacitor before you begin the test.
