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
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.
Heater / element fault
MediumSymptoms: No heat, overheat alarm.
Root cause: Element or thermal fuse failure.
Temperature sensor drift
MediumSymptoms: Setpoint error, alarm.
Root cause: Sensor aging.
Fan / airflow failure
LowSymptoms: Uneven warming, hotspot.
Root cause: Blower wear.

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 structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Heater / element fault
- Confirm the presentation - typically no heat, overheat alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: element or thermal fuse failure.
- 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 heating element / thermal fuse 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: Fan / airflow failure
- Confirm the presentation - typically uneven warming, hotspot - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: blower wear.
- 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 blower fan 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.
