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.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
High-voltage capacitor failure
HighSymptoms: Charge fails or sluggish, low-energy delivery.
Root cause: Capacitor aging / leakage.
Paddle / electrode fault
HighSymptoms: No shock delivered, pad error.
Root cause: Worn paddles or expired pads.
Charge / discharge relay fault
HighSymptoms: Won't charge or discharges unexpectedly.
Root cause: Relay/contactor wear.
SELV / patient isolation fault
MediumSymptoms: Leakage alarm, self-test fail.
Root cause: Failed isolation components.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily/shift visual and self-test check (AAMI EQ56 daily-ready standard)
- ·Battery and pad expiration-date tracking
- ·Energy-delivery accuracy test against a defibrillator analyzer
- ·Paddle/cable continuity check
- ·Annual full PM
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.
