Key tips

·Never skip the daily/shift ready-check - a defibrillator found dead during a code is a real, repeated root-cause finding.
·Pads and batteries have real expiration dates - check them on every PM, not just at annual service.
·Verify energy-delivery accuracy with a real defibrillator analyzer, not just a self-test pass.

Troubleshooting Approach

A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.

Symptom: High-voltage capacitor failure

Confirm the presentation - typically charge fails or sluggish, low-energy delivery - and note the exact alarm or message and the conditions when it occurs.
Check the most likely cause first: capacitor aging / leakage.
Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
If the fault is confirmed and not a field adjustment, service or replace the rechargeable battery pack per the manufacturer's service documentation.
Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
Record the findings, any parts used, and the verification results in the maintenance history.

Symptom: Battery degradation

Confirm the presentation - typically short charge-hold, low-battery on readiness test - and note the exact alarm or message and the conditions when it occurs.
Check the most likely cause first: aged battery pack.
Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
If the fault is confirmed and not a field adjustment, service or replace the hV energy storage capacitor per the manufacturer's service documentation.
Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
Record the findings, any parts used, and the verification results in the maintenance history.
