[Shop-talk] To kill a refrigerator

[Steven Trovato]

I assume you have a plan to keep all of their food from spoiling 
during this sabotage event?  Also, no matter what you do, if they're 
going to call a serviceman, that seems like a big unnecessary 
expense.  If they're not going to call  a serviceman, then just 
disconnecting anything will do the trick.  Unless this old lady is a 
retired engineer or something, she's probably not going to analyze the wiring.
