How do you check the amperage on a refrigerator compressor?
- Pull the refrigerator away from the wall and locate the compressor with a flashlight.
- Divide that number by 120 volts, which is the voltage of your power supply, to get the current that the refrigerator draws in amperes.

Also asked, how many amps should a refrigerator compressor draw?
Refrigerator amps mean the amount of electrical energy used by a refrigerator compressor to cool down the compartment. For most domestic fridges, the amperage ranges between 3 and 5 in the case of 120 V. You need a dedicated 15 – 20 amp circuit as the in-rush amperage is significantly more.
Additionally, what are some of the symptoms of an inefficient compressor? One of the symptoms of an inefficient compressor is high suction pressures along with low discharge (head) pressures. If the compressor is inefficient, the evaporator cannot handle the high heat load due to a decreased refrigerant flow rate, and the conditioned space temperature will start to rise.
Correspondingly, how do I know if my fridge compressor is broken?
When to replace:
- When the freezer side is not cooling properly (0 degrees).
- When there's a humming noise coming from the compressor. (This can indicate the compressor is defective.)
- If the fridge is 15 years or older.
- If the repair costs more than half the price of a new fridge.
Can I run a refrigerator on a 15 amp circuit?
Power Consumption With a 110-volt current, a 750-watt appliance will require 6.8 amps to operate. A refrigerator will use roughly half of the available amperage of a standard 15-amp circuit, and over one third of a 20-amp circuit.
