Can you replace a start capacitor with a higher UF?
An electric motor start capacitors can be replaced with a micro-farad or UF equal to or up to 20% higher UF than the original capacitor serving the motor.
What happens if I use a bigger start capacitor?
Much the same way, a motor will not run properly with a weak capacitor. This is not to imply bigger is better, because a capacitor that is too large can cause energy consumption to rise. In both instances, be it too large or too small, the life of the motor will be shortened due to overheated motor windings.
Does start capacitor size matter?
Sometimes (or even usually) there is no real difference, so you can choose depending on the size itself: if you solder by hand, bigger size can be an advantage.
Can you use a bigger start capacitor?
Larger than needed microfarad values will not cause much of any problems (especially for a start capacitor). A larger than needed run capacitor will not have any real affect. Depending on the cap and motor it could improve efficiency or decease efficiency very slightly.
Will a motor start with a bad start capacitor?
A start capacitor is only used in the motor circuit for a second or two when it first starts to turn. Once the motor is up to speed, the start capacitor disconnects and is not used again until the next time the motor starts. If the start capacitor fails, then the motor will not be able to begin turning.
Will a motor start with a bad run capacitor?
When a capacitor short-circuits, the winding in the motor may burn out. When a capacitor deteriorates or opens, the motor has poor starting torque. Poor starting torque may prevent the motor from starting, which will usually trip the overloads.
Do start capacitors get weak?
A motor with a short-circuitedCapacitor will usually start and run but with less starting Torque andrpm than normal. Capacitors in metal housings can become grounded. Not starting to weak starting and running are some of the symptoms of grounded Capacitors.
