UPS Fan and Capacitor Replacement Service

Help extend the reliable operating life of your uninterruptible power supply with professional UPS fan and capacitor replacement.

Cooling fans and capacitors are critical internal components that naturally wear and deteriorate over time. Aging fans can reduce airflow and allow excessive heat to build inside the UPS, while deteriorating capacitors can affect system performance and increase the risk of an unexpected failure.

Proactively replacing these lifecycle components can improve system reliability and help reduce the risk of unplanned downtime.

Typical Scope of Service

UPS fan and capacitor replacement may include:

• Visual inspection of the UPS and accessible internal components
  
• Review of active alarms and operating conditions
  
• Controlled shutdown and transfer to bypass when required and permitted
  
• Removal of aging cooling fans and/or capacitors
  
• Installation of approved replacement components
  
• Inspection of internal wiring, connections, and surrounding components
  
• Cleaning of accessible internal areas
  
• Verification of fan operation and system airflow
  
• UPS startup and return to normal operation
  
• Review and clearing of applicable alarms
  
• Functional testing after replacement
• Written service report documenting completed work and system condition

The exact scope will depend on the UPS manufacturer, model, configuration, site conditions, and the components being replaced.
