For those with a start capacitor, make sure to test the capacitor to see if it is good. Testing is done using the multimeter''s capacitance reading. Set the meter to MFD or uF which both stand for micro-farad. Next, take a 10,000 Ohm resistor and rub across the start capacitor to remove the residual voltage.
How to distinguish between Thermistor, Varistor and disk capacitor?
Disk capacitors are often a dull tan/orange with no gloss. MARKINGS. Capacitors usually start with a 3-digit number like "104" (100nf or 0.1uF), but might have some other markings that indicate other characteristics. Common kinds of thermistor are "NTC" (negative temperature coefficient) and "PTC" ("positive temperature coefficient) …
Everything You Need to Know About Capacitor Polarity
Capacitors used in electronic devices can be categorized into polarized capacitors and non-polarized capacitors based on their polarity. Therefore, designers need to identify and correctly install capacitors'' polarity during circuit design to ensure the circuit''s normal operation and long-term stability.

How to Use NTC Thermistors for Inrush Current Limiting
At the time of powering on an electronic device such as a switch-mode power supply or an inverter, the device is charged with an instantaneous abnormal current with a high peak. It is called an inrush current, and without protection, it may destroy a semiconductor device or have a harmful effect on the service life of a smoothing capacitor.

What Is An NTC Thermistor | Ametherm
This zero-power resistance is the dc resistance value of the thermistor when measured at a specific temperature with a low enough power dissipation from the thermistor for any further power decrease resulting in no more than the smaller of 1/10 of the particular measurement tolerance or a zero point one percent change in the resistance .
Inrush current
An example of inrush current transients during capacitor bank energization. Inrush current, input surge current, or switch-on surge is the maximal instantaneous input current drawn by an electrical device when first turned on. Alternating-current electric motors and transformers may draw several times their normal full-load current when first energized, …
6.1.2: Capacitance and Capacitors
A capacitor is a device that stores energy. Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates separated by air. ... They usually are polarized, meaning that the leads must match the polarity of the applied voltage. Inserting them into a circuit backwards can ...
