What This Guide Helps With
Troubleshooting loss of power, abnormal display operation, Power Fail/System Fail alarms, or alarm conditions caused by external connections or setup issues.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
If the Resuscitaire is supporting an infant, notify clinical staff and move the infant to another approved warming/resuscitation device before troubleshooting.
Do not continue using the warmer when power, display, or alarm operation is unreliable.
Expected outcome: The infant is safely supported by alternate equipment before the affected warmer is evaluated.
Why it matters: The Resuscitaire provides warming support and may include resuscitation components used during neonatal stabilization. A power, display, or alarm fault can prevent dependable monitoring or warming operation.
2. Confirm the Reported Fault
Power on the unit, if safe to do so, and observe the control panel for:
- No display or no response to power-on
- Intermittent display operation
- Power Fail indication
- System Fail indication
- Probe, Baby Temperature, High Temperature, or Check Patient alarm
- Audible alarm without an obvious visual indication
- Any reported error code or unusual display characters
Document whether the fault is constant, intermittent, or occurs only during startup or warming operation.
Expected outcome: The actual alarm, display, or power symptom is identified before parts or accessories are suspected.
If the reported condition cannot be reproduced: Perform normal operational verification according to department procedure before returning the device to service.
3. Inspect for Obvious Damage or Unsafe Conditions
Disconnect the unit from patient use and inspect the warmer externally for:
- Damaged power cord or plug
- Loose power inlet connection
- Cracked, wet, or damaged control panel
- Signs of fluid intrusion
- Burnt smell, unusual heat, discoloration, or arcing evidence
- Damaged heater head, column, or accessory attachments
Expected outcome: No external damage or hazardous condition is found.
If damage, liquid intrusion, burning odor, or excessive heat is present: Stop troubleshooting, remove the device from service, and send it for repair evaluation.
4. Verify the AC Power Source
Confirm the warmer is connected directly to an approved hospital-grade outlet. Test the outlet with an appropriate outlet tester or a known-working clinical device in accordance with facility practice.
Do not rely only on the room’s wall indicator or assume the outlet is functional.
Expected outcome: The outlet provides reliable AC power.
If the outlet is defective or switched off: Move the warmer to a verified outlet and retest. If normal operation returns, document the external power-source issue and stop.
Why it matters: The Resuscitaire identifies interrupted AC power as a Power Fail condition.
5. Inspect the Power Cord and Connection
Verify that the power cord is fully seated, secured where applicable, and free from cuts, exposed conductors, loose blades, bent pins, or evidence of strain.
Gently check whether movement of the cord or plug causes the display or power indication to flicker.
Expected outcome: The unit remains powered consistently without intermittent operation.
If a removable cord is damaged or suspect: Replace it with an approved known-good cord and retest.
If power or display operation still cuts out with a verified outlet and known-good cord: Remove the device from service for bench evaluation.
6. Check the Power Switch and Startup Behavior
With the warmer connected to verified AC power, turn the unit on and observe whether:
- The display activates normally
- Indicator lights illuminate appropriately
- Audible alarms activate unexpectedly
- The heater or mode indicators respond
- The display blanks, resets, or freezes during startup
Expected outcome: The controller powers on and remains stable without an unresolved fault indication.
If the unit does not power on, repeatedly resets, has a blank or unreadable display, or indicates System Fail: Do not continue clinical use. Remove it from service for repair evaluation.
7. Differentiate a Power Fault From a Clinical Alarm Condition
If the display is operating but an alarm is active, identify the alarm category before assuming the controller has failed. The Resuscitaire controller may indicate:
- Power Fail: AC power interruption
- System Fail: system malfunction
- Probe: shorted, open, or absent skin temperature probe
- Baby Temperature: measured skin temperature outside the set-point tolerance
- High Temperature: excessive measured skin temperature
- Check Patient: required attention during Manual Mode operation
Expected outcome: A correctable accessory or operating-condition alarm is distinguished from a power or internal system fault.
If a System Fail indication is present: Stop and escalate; do not attempt to clear it through repeated operation.
8. Check the Skin Temperature Probe and Connector, When Applicable
If the alarm is related to Probe, Baby Temperature, or unexpected skin temperature display behavior:
- Confirm that the correct compatible temperature probe is connected.
- Inspect the probe connector, cable, and sensor end for damage, contamination, or loose connection.
- Disconnect and firmly reconnect the probe.
- Substitute a known-good compatible probe, when available.
Expected outcome: A functional probe is recognized and temperature-related alarm behavior resolves when the accessory was the cause.
If replacing or reseating the probe resolves the issue: Verify normal operation and document the defective or loose probe as the cause, then stop.
If the fault remains with a known-good probe: Remove the warmer from service for further evaluation.
9. Check Whether the Alarm Is Related to Manual Mode Operation
If staff report repeated alarm activation while the warmer otherwise powers and displays normally, confirm whether the unit was operating in Manual Mode.
The Resuscitaire includes a Check Patient alarm function during Manual Mode operation; this may be reported as a device alarm even when the display and power system are operating normally.
Expected outcome: The reported alarm is correctly identified as either expected mode-related behavior or an unresolved abnormal condition.
If expected alarm behavior is confirmed: Educate the reporting department as appropriate, document the finding, and complete operational verification before return to service.
10. Evaluate Display Reliability During Basic External Testing
Observe the display while performing safe, non-patient testing:
- Does the display remain readable?
- Do segments or indicator lights appear missing?
- Does the display flicker when the unit is moved or the cord is repositioned?
- Does the unit show inconsistent values or unexplained error indications?
- Can the alarm condition be matched to an external cause?
Expected outcome: The display remains stable and provides reliable information.
If the display is blank, incomplete, frozen, flickering, or unreliable after power and accessory checks: Remove the unit from service. A warmer with an unreliable display cannot be trusted for clinical use.
11. Perform Final Operational Verification
After resolving an external issue such as outlet failure, damaged cord, loose connection, or defective probe, complete the department-approved operational and safety verification before returning the warmer to use.
Confirm:
- Stable AC operation
- Normal display function
- Appropriate alarm indication and audible response
- Proper recognition of connected accessories
- No abnormal heat, smell, or intermittent behavior
- Device status is clearly documented
Expected outcome: The warmer operates normally and passes required verification.
If any alarm, display, or power concern remains unresolved: Do not return the unit to service.
If the Problem Persists
If the Resuscitaire continues to have a blank or unreliable display, unexplained alarm behavior, System Fail indication, repeated power interruption, or inability to operate normally after external checks, common external causes have been ruled out and the fault is likely internal.
The device should be:
- Removed from service
- Labeled Out of Service
- Sent for repair or bench evaluation
Knowing when to stop is proper troubleshooting. Do not continue attempting to operate an infant warmer with unresolved alarm, display, or power reliability concerns.
Clinical Use Tip
Do not troubleshoot an infant warmer while it is actively supporting an infant. Move the infant to another approved warming/resuscitation device first, then evaluate the affected warmer only when it is safe to do so.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical staff reported that the Drager Resuscitaire displayed a Power Fail alarm and intermittently lost the control panel display during setup."
Cause
What was observed during troubleshooting.
Example:
"Found the warmer connected to a faulty AC receptacle that did not provide stable power; the warmer operated normally when connected to a verified outlet."
Resolution
What action was taken.
Example:
"Removed the original outlet from use through the appropriate facilities process, verified stable warmer power and display operation from a known-good outlet, completed operational checks, and returned the device to service."
Helpful Details to Include (If Known)
- Outlet tested and result
- Power cord condition and whether a known-good cord was substituted
- Alarm message or indicator observed
- Display behavior during startup and testing
- Mode in use when the alarm occurred
- Skin temperature probe condition and substitution result
- Presence of unusual sound, heat, odor, or fluid exposure
- Whether the problem was reproducible
- Final device status: returned to service or removed from service
Final Thought
An infant warmer with unreliable power, alarm operation, or display function must be approached cautiously. Start with patient safety, rule out simple external causes logically, and escalate promptly when reliable operation cannot be confirmed. Clear CCR documentation preserves the troubleshooting path and supports safe equipment decisions.
That is successful troubleshooting.
