Electrolux Refrigerator Hissing and Popping: Identify the Cycle Before Calling for Service

Electrolux documents hissing or sizzling during defrost when water drips onto the defrost heater, followed by possible popping after defrost. It also says popping or cracking when the compressor starts can come from metal expansion and contraction or refrigerant circulation and may level off as the appliance runs.
