Why is it not recommended to install a surge protector in the refrigerator
A typical surge protector passes the electrical current along the outlet to number of the devices plugged into the power strip. If the voltage happens to rise above the acceptable level, the protector will divert the extra electricity into the outlets grounding wire.
We do not recommend connecting a refrigerator or freezer to a surge protector. The compressor is sensitive to temperature and current overloads, and will shut itself down with a surge. ... A surge protector will override this system, and if there is a power surge, your refrigerator may not restart.
The recommended surge protector for a refrigerator is NONE.
A refrigerator is basically just a compressor motor, and electric motors are not delicate. In fact, about the only thing in your house more impervious to surges or drops are the burners in an electric stove or electric baseboard heaters.
Consider surge protectors for computers, TV's, stereo equipment, and similar electronic gear. But don't worry about your refrigerator.
