Is it cheaper to repair or replace an electrical panel?

It is almost always cheaper to repair an electrical panel than to replace the entire panel, but repair is only appropriate for minor issues and may not be safe or code-compliant for major problems. Minor repairs such as replacing a single faulty breaker, which costs 20 to 100 dollars for the breaker plus 100 to 200 dollars in labor, tightening loose connections, replacing a damaged bus bar cover, or adding a few new circuits typically cost 150 to 500 dollars total. These repairs make sense if the panel is relatively new, is a reputable brand like Square D QO or Homeline, Siemens, or Eaton, has sufficient capacity, and shows no signs of overheating or damage. However, there are situations where replacement is necessary despite higher cost. If the panel is an outdated or unsafe brand like Federal Pacific Stab-Lok or Zinsco, has extensive rust or water damage, has melted bus bars, is overloaded and has no more space, is only 60 or 100 amps and you need 200 amps for modern loads, or repeatedly trips, repair is not safe and replacement is the only code-compliant option. While replacement costs 1,500 to 4,000 dollars, it is cheaper in the long run than risking a fire or repeatedly repairing a failing panel. A licensed electrician can assess whether repair or replacement is the safer and more economical choice for your situation.
