Repair Process

Each FENWAL 550 control unit is diagnosed using schematics and specialized test equipment to find the root cause of the failure before any repair work begins.

  • Trace and Signal Analysis: We analyze the circuit board for broken traces or weak signals that could cause intermittent faults.
  • Sourced Components: Replacement parts are sourced from our inventory or reliable suppliers for a quality repair.
  • Static-Safe Environment: All work is performed in an ESD-safe environment to protect sensitive electronic components.

Testing and Bench Verification

Our quality check includes live testing of the repaired unit. We verify all inputs, outputs, and communication ports before the FENWAL 550 ships. Our system integration analysis confirms proper functionality.
