Key tips
- ·Never skip temperature-accuracy verification to save time - it's the one check that directly prevents burns.
- ·Hose/blanket connector wear is the most common real fault and the easiest to miss on a quick visual check.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Air- or radiant-heater control fault
HighSymptoms: Chamber / patient will not reach or hold the set temperature, temperature alarm, self-test fault; "Check" test shows a failed LED / lamp / buzzer.
Root cause: Heater element / infrared rod, the air- or skin-temperature sensor, the fan (incubator), or a control-board fault.
Skin-temperature (servo) control fault
HighSymptoms: Servo mode does not regulate to the skin probe, deviation alarm, probe-fault alarm.
Root cause: Damaged skin temperature probe or its connector, or the servo-control circuit.
Alarm / central-alarm-lamp / buzzer fault
MediumSymptoms: No or quiet audible alarm, central alarm lamp does not light on the "Check" test.
Root cause: Buzzer / speaker, the central alarm lamp, or the alarm board - a safety-critical failure.
Heated-mattress / gel-pad fault (warmer models)
MediumSymptoms: Mattress heating uneven or not warming, mattress-temperature alarm.
Root cause: Mattress heating element or its sensor.
Humidity / airflow fault (incubator)
MediumSymptoms: Set humidity not reached, uneven chamber temperature, airflow alarm.
Root cause: Humidifier reservoir / heater, or a worn circulation fan / blocked filter.

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.
- ·Hose / blanket connector inspection
- ·Temperature-accuracy verification
- ·Annual electrical safety test
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Heater / temperature control fault
- Run the readiness / self-test; on Draeger press "Check" and confirm the LEDs, LED strip, central alarm lamp and buzzer.
- Set a target temperature and confirm the unit reaches it.
- Compare the chamber / skin temperature to an independent calibrated reference.
- Check the fan runs and the air filter is clean (incubator).
- Replace the temperature sensor, heater element or infrared rod as isolated.
Symptom: Servo / skin-probe fault
- Fit a known-good skin temperature probe and confirm good skin contact.
- Check the probe connector and cable.
- Verify the servo regulates to the probe with a warm reference.
- Replace the probe.
- Refer the servo-control circuit for service if it still will not regulate.
