Refrigeration And Defrost Component Checks Made At High Voltage Board - Amana B136CAL3 Technical Information

Electronic Functional Description
WARNING
To avoid electrical shock which can cause severe personal injury or death, disconnect power to refrigerator
using power switch before servicing. Wires removed during disassembly must be replaced on proper
terminals to insure correct earthing and polarization. After servicing, reconnect power using power switch.
