Most standard full-size refrigerators use between 3 and 6 amps during normal operation, though some models can draw up to 15 amps. Mini or compact refrigerators typically use from 0.5 to 2.5 amps. The typical household refrigerator runs on a dedicated 15- or 20-amp circuit to accommodate both the running current and the higher surge current when the compressor starts. During startup, refrigerators can draw a surge of 3 to 8 times their normal running current for a few seconds. For example, a refrigerator running at 3 amps may momentarily require 9 to 18 amps at startup. This surge is why circuit breakers for refrigerators need to have sufficient capacity. In summary:
- Average running amps: 3 to 6 amps for full-sized refrigerators
- Startup surge amps: Up to 15 amps or higher for brief periods
- Mini refrigerators: Under 1 to 2.5 amps running
- Dedicated circuit: Typically 15 or 20 amps required for safe operation
These values depend on the refrigerator's size, age, model, and features such as ice makers and defrost cycles, which can add to the current draw.
