The SNUBBER prevents Main PCB malfunction from sparks occurred by other electrical
component’s ON/OFF. ( SNUBBER =Spark killer)
Because of the SNUBBER, 115 voltage is always detected, but electrical current in this
case is very little (small Amps.).So, this electrical current is not enough to operate the
evaporator defrost heater.
