Frequently Asked Questions
How much does it cost to fix a refrigerator that's noisy or clicking compressor?
The part costs about $22. If you do it yourself, that's your total cost. A professional service call would add $100-200 in labor, bringing the total to $172.
How long does this refrigerator repair take?
This repair is rated "easy" and typically takes 15-20 minutes. The most time-consuming part is usually accessing the component, not the actual swap.
What if this isn't the problem?
Our diagnosis is 60% likely based on the symptom you described. If replacing this part doesn't fix it, the next most common cause for "clicking sound every few minutes, or loud humming from the back" would be related to the wiring harness or control board. In that case, consider calling a professional.
Should I just replace my refrigerator instead?
A new refrigerator costs $800-2,500. If yours is well under 12-17 years old, a $22 repair is far more cost-effective. If it's near end-of-life and has had multiple issues, replacement starts making more sense.
