Responded to service call regarding HVAC system repeatedly generating fault alerts and requiring manual resets to restore operation. Upon arrival, performed full diagnostic evaluation of the system, including control board fault code review, sensor resistance checks, and system performance verification. Troubleshooting revealed a failed evaporator coil temperature sensor providing inaccurate temperature feedback to the control board, resulting in system lockout conditions. Further diagnostics confirmed a failed suction line temperature sensor, causing improper superheat monitoring and triggering protective fault alerts. Verified wiring integrity, checked sensor resistance values against manufacturer specifications, and confirmed both sensors were operating outside acceptable parameters. Recommended replacement of the evaporator coil sensor and suction line sensor to restore proper system monitoring, prevent nuisance lockouts, and ensure reliable system performance. System left in sa
