This post explains for the varistor. A Metal Oxide Varistor (MOV) is a type of voltage-dependent resistor that is designed to protect electronic circuits and devices from transient voltage surges or spikes. It is composed of a ceramic-like material made primarily of metal oxides, typically zinc oxide (ZnO) mixed with other additives.
The Part Number is JVR-14N391K.
The function of this semiconductor is METAL OXIDE VARISTOR.
Manufacturer: RFE

Description
This is 390V, 14mm Disc, METAL OXIDE VARISTOR. Metal oxide varistors are widely used in various applications to suppress and absorb high-energy transients. They are commonly found in power distribution systems, surge protectors, electronic equipment, industrial machinery, and telecommunications devices. By absorbing and dissipating the excess energy as heat, MOVs help prevent voltage-sensitive components from experiencing voltage levels that could cause malfunction or failure.
