That 50-foot 12-gauge cord is fine for your fridge.

Yes, it should work without damaging the compressor. A refrigerator typically draws 6–10 amps, and a 12-gauge cord at 50 feet will have a voltage drop of less than 2% — well within safe range.

The real risk with extension cords and compressors is voltage drop so severe the motor struggles to start (brownout conditions) and overheats. But with 12-gauge at that length, you’re not even close to that danger zone. This is a thick, properly sized cord.

One thing: make sure the cord is rated for outdoor use if it’s in a garage (most 12-gauge cords are). And don’t coil the extra length tightly — that can create inductance and heat. Uncoil it.

This is not where you save money on a thinner gauge.
