Q: What else should I know about Starter Capacitors before I buy one?A: Due to the quick burst of energy the starter capacitor is designed to produce, burn outs can sometimes occur. If your motor is either not turning on at all, or is slow to start, these are two easily identifiable signs that the starter capacitor is not functioning normally. In the event that the motor is simply slower than usual, overuse and age may have caused your starter capacitor to lose its capacitance rating. It is possible, though, that you may have other issues with your motor that have nothing to do with the capacitor. Due to the relative ease and low cost of replacing a starter capacitor it is a good place to start, as it may solve your problem with little hassle. The starter capacitor may, in some cases, overheat and/or rupture. One cause of this may be overvoltage, where a sudden surge of voltage will cause a buildup of pressure. In other cases, as relays open and close, electric sparks can cause the contacts to stick together. This is known as a sticking relay, and it can lead to failure if the starting circuit is left energized too long, as starter capacitors are not meant to be used for more than a few seconds. This is a problem that may lead to complete failure, where the top of the starter capacitor will pop off and the insides may be partially or fully ejected. Another cause of overheating can be the mechanical devices that cycle often, such as air compressors. Starter capacitors that cycle above 20 starts, or cycles per hour, may be subject to overheating. If any of these do occur and damage the capacitor, simply replace it. In more serious cases, the motor's starting circuit might be engaged too long for the intermittent duty rating of the start capacitor. The top of the start capacitor may become dislodged, and the insides may, in some cases, be partially or fully ejected. If start capacitors are left energized too long due to a faulty starting circuit on a motor they can overheat. Similarly, but not quite as dramatic, a start capacitor may just exhibit a ruptured pressure relief blister. If any of these do occur, and damage the capacitor, it must simply be replaced.

Q: How do I select the correct Starter Capacitor for my needs?A: The majority of starter capacitors will come with specs in the same range: Voltage – 110/125, 165, 220/250 or 330 VACFrequency – 50 or 60 HzCapacitance – 50 to 1200 uf When replacing a starter capacitor, the same capacitance and frequency as the original capacitor must be used. You can choose a new capacitor with a voltage that is in the range of the operational voltage of the motor; a capacitor will have a marked voltage indicating peak voltage acceptable. Starter capacitors will have either a black plastic or phenolic case, thought this will not have any bearing on how well the capacitor will work. The starter capacitor will also have a recessed top where the connections are located. E-mail/Skype: info@dfcapacitor.comTel/WhatsApp: +86 15057271708Wechat: 13857647932Skype: Mojinxin124
Q: What are typical start capacitor ratings?A: Most start capacitors have ratings of 50-1200 uf capacitance and voltages of 110/125, 165, 220/250 or 330 VAC. They are also usually always 50 and 60 Hz rated. Case designs are typically round and cast in black phenolic or Bakelite materials. Terminations are usually ¼" push on terminals with 2 terminals per connection post. E-mail/Skype: info@dfcapacitor.comTel/WhatsApp: +86 15057271708Wechat: 13857647932Skype: Mojinxin124
Q: How Does Start Capacitor Help Start MotorA: Permanent Split Capacitor Motors or PSC Motors use run capacitors to help the motor be more efficient while running. The start capacitor gives the motor a boost on startup. The run capacitor helps the motor run more efficiently. Many types of HVAC equipment use PSC motors as blowers and pumps.

Q: What is the difference between round and oval capacitors?A: The only difference between round capacitors and oval ones is the case. There is no electrical difference. As long as the replacement will fit within the space provided, the case shape is irrelevant. E-mail/Skype: info@dfcapacitor.comTel/WhatsApp: +86 15057271708Wechat: 13857647932Skype: Mojinxin124

Q: How to choose the fan start capacitor?A: CBB61 capacitors are generally used in fans, ceiling fans, range hoods, heaters and other electrical appliances. The size of the capacitor is generally related to the size of the fan. The 16 inch generally uses 1.5UF, the 12-14 inch generally 1.2uf, and the 8-10 generally 1uf. The ceiling fan is 2.2-3UF, and the range hood is generally 4UF. If you don't know the size, it is recommended to use 1.5UF for floor fans, desk fans, and wall fans. The ceiling fan uses 2.5UF.

Q: How Does Start Capacitor Help Start MotorA: A shaded pole electric motor does not use a run or start capacitor.Shaded pole motors are inefficient.PSC motors are used extensively in HVAC.PSC Motors can be replaced with the more efficient variable speed ECM Motor.Run capacitors help the PSC run more efficiently.Start capacitors help the motor start.A potential or current relay takes the start capacitor out of the circuit after the start-up.Capacitors change the phase angle of the EMF.Changing the phase angle gives the motor a better boost.Finally, a 3-phase motor does not use capacitors.

Q: What is a dual run capacitor?A: Dual run capacitors are 2 run capacitors in one case. They have nothing else that makes them electrically special. They generally have connections marked "C" for "common", "H" or "Herm" for "Hermetic Compressor" and "F" for "Fan." They will also have 2 different capacitor ratings for the 2 different parts. You might see 40/5 MFD, meaning that one side is 40 microfarads (measurement of capacitance) and the other side is 5 microfarads. The smaller value will always be connected to the fan. The larger connection will always be connected to the compressor. E-mail/Skype: info@dfcapacitor.comTel/WhatsApp: +86 15057271708Wechat: 13857647932Skype: Mojinxin124
Q: How is a run capacitor different from a start capacitor?A: Start capacitors give a large capacitance value necessary for motor starting for a very short (seconds long) period of time. They are only intermittent duty and will fail if energized too long. Run capacitors are used for continuous voltage and current control to a motors windings and are therefore continuous duty. They are generally of a much lower capacitance value. E-mail/Skype: info@dfcapacitor.comTel/WhatsApp: +86 15057271708Wechat: 13857647932Skype: Mojinxin124
Q: What do you need to know when selecting a dual capacitor?A: Capacitance - The capacitance of the replacement capacitor must match that of the original. Voltage - The voltage rating on your dual capacitor must be equal to or exceed your system voltage. Case style/form factor - Run capacitors come in either round or oval cans. A round dual capacitor can be used in place on an oval one, and vice versa. As long as your dual capacitor fits in the mounting space you have in your unit, the case style doesn’t matter.
