Q. Our home inspector said that we should not plug our deep freeze into a GFCI circuit, because it could trip while we are away, and ruin our food. Is this correct?
A. Yes, your home inspector is correct. Appliances such as refrigerators and freezers or medical equipment that must remain running should never be connected to GFCI outlets. The reason for this is that GFCI outlets can trip without warning shutting off power to the appliance. GFCI outlets are very sensitive to changes in their environment, and can trip under various conditions. These outlets when placed outside or in garages can trip during rainy weather, because there is too much moisture in the air. GFCI outlets that are wired to other similar devices can turn off when one of the other outlets trips. Under normal circumstances, GFCI outlets are perfectly suited for such things as small appliances, bathrooms, kitchens and exterior devices such as hedge trimmers and power tools. When used properly, GFCI outlets are life savers, but because they are so sensitive and prone to tripping without warning, they are ill suited for appliances which must remain on at all times.
