A dual run capacitor supports "TWO" electric motors , one section for the condenser fan motor and the other for the compressor motor . Beacause of technological innovation, the dual run capacitor can saves space by combining two capacitors into one case. Round cylinder-shaped dual run capacitors are commonly used for air conditioning, it can help in the starting of the compressor and the condenser fan motor . Air conditioner capacitor is small in size, lightweight , heat resisting and anti-explosion . Capacitors come in a variety of sizes, but depending on the capacitance (µF or MFD) and the voltage. VEXUNGA Air Conditioner Capacitor is A Good Choice !!! SPECIFICATIONS Model: CBB65B （Universal model） Operating temperature: -40℃ to +70℃/-104℉ to +158℉ . Frequency: 50/60 Hz . Dual capacitors have three terminals, three terminals on the top are labeled "Herm"/"H" for the compressor motor - White Cap , "Fan"/"F" for the fan - Green Cap , and "C" for the common line - Black Cap . "WHEN” to Replace AC Capcitor - The air conditioner's fan wouldn't spin - stopped working . - The air conditioner hummed , but no air flow. - The ac fan would spin intermittingly and the external pump would not start . - The air conditioner stopped cooling - the compressor in the condenser maybe not coming on. - As the capacitor gets older , the motor may get louder and seem to run slower . You can extend the life of your motor if you replace them before they become weak. Eventually the capacitor will become too weak to start the motor, and if the motor won't start it may be shorted. Timely replacement of capacitors is crucial to air conditioner maintenance . "VERY EASY” to Replace AC Capcitor First of all, Turn off the power to the air conditioner. Secondly, Take out the ac capacitor. Finally, Make sure that you know which wire is for which terminal - direct replacement without changing wiring or adapters & Confirm the appropriate capacitance (µF or MFD) and voltage. What's important, Replace air conditioner capacitor by yourself that will save you a lot of money and time . 55/5 uF Capacitor Replacement for P291-5554RS , P291-5553R , TT-CAP-55/5/440 , cap050550440rtp , cap050550440rt , TRCFD555 , 97Z9839BZ3 , Z97F9839 , 97F9839 , 97F9839BX , CPT00670 , P2915554RS , TP-CAP-55/5/440R , HCKS550D050R440Z and so on.

Review: Works like a charm in my Payne outdoors AC - My Payne outdoor AC Model PA10JA060 fan stopped functioning. Replaced the current capacitor with this one of the same specs and the unit came back to life. This is a no brainer to have as a spare considering it is 50% less than the cost of just the initial visit from the AC man, not to mention the $150+ they would most likely charge for a replacement. This took 20 minutes to replace. A clear win for the DIY here! Review: Fixed My A/C Problem - Item arrived quickly, easy to install, and got the A/C working again. You wouldn't think anyone would need air conditioning in Mid-December, but this is Southeast Texas so we never know if a cold front will make it this far down south. Yes, 84 degrees can happen here in December! ## Features - VEXUNGA 55+5 uF ±6% 370/440 VAC CBB65 dual run start capacitor replacement for BOTH 370 & 440 Volt capacitors. - 55/5 MFD Capacitor size measures ( 2.36inch / 60mm ) in Diameter x ( 3.35inch / 85mm ) in Height. - Operating temperature: -40℃ to +70℃/-104℉ to +158℉.
