Main Disconnect Repair
Fixing Issues with Main Disconnects
Understanding the Main Disconnect
- Difficulty turning the switch on or off
- Breakers tripping when the disconnect is operated
- Buzzing or humming near the switch housing
- Visible corrosion or burn marks
- Partial or complete power loss to the home
These problems require immediate attention to prevent further electrical damage.
Our Diagnostic and Repair Process
MAD Energy NW begins by inspecting the disconnect assembly, breaker connections, and service line terminals to determine the source of failure. Using proper testing equipment, we evaluate voltage flow and grounding to confirm the switch’s integrity.
Our process includes the following:
- Checking mechanical movement and switch alignment
- Cleaning and reterminating corroded connections
- Replacing worn or burned contacts
- Testing continuity and insulation strength
- Verifying safe operation after all work is complete
Every repair is performed following Washington State’s electrical safety standards and manufacturer specifications.
When Replacement Is Necessary
If the disconnect shows severe corrosion, melting, or an outdated design, replacement is often the safest choice. Installing a new, code-approved main disconnect ensures reliable control of your home’s electrical power and proper emergency shutdown when required.
Our electricians replace components with compatible, high-quality materials designed for long-term use and safety.
Preventive Maintenance
Routine inspections help keep disconnects in proper working order. During scheduled maintenance, MAD Energy NW checks for signs of oxidation, wear, or improper torque on connections to prevent potential shutdowns. Keeping the disconnect clean and protected from moisture extends its lifespan and performance.
