Cesca Therapeutics Thermogenesis MT204
Cesca Therapeutics · Model Thermogenesis MT204
The Thermogenesis Thermoline™ plasma thawers represent the latest in rapid and reliable thawing of plasma and cryoprecipitate. There is no contact between the plasma pack and the water There as an agitation action included to further speed up thawing.
Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
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.
"LOW FLD" low-fluid alarm
MediumSymptoms: "LOW FLD" on the temperature/error display; the thawer is disabled at rest or at the end of a cycle until refilled and RESET is pressed.
Root cause: Water below the recommended operating level, a ground problem, or a corroded level probe.
Overtemperature (Overtemp) condition
HighSymptoms: Unit disabled with an overtemp condition.
Root cause: Incorrectly calibrated operating temperature, a temperature-sensor fault, or a heater/control fault.
Agitation not working
MediumSymptoms: No agitation action during a thaw, slow thawing.
Root cause: Agitation motor or drive-linkage fault.
Slow or incomplete thawing at temperature
MediumSymptoms: Cycles run long, plasma not fully thawed.
Root cause: Weak heater or poor water circulation.

- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
Error Codes
Extracted directly from this unit's own service manual.
OVER TEMPIf an overtemp condition occurs, the operating temperature/error message display will flash "OVER TEMP".
LOW FLD"LOW FLD" will be displayed on the operating temperature/error message display when the water is below the recommended operating level.
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: LOW FLD alarm
- Fill the bath to the safe operating level.
- Press RESET (only with the equipment at rest).
- If the alarm persists at a correct level, check the equipment ground.
- Inspect the level probe for corrosion and replace if needed.
- Confirm the thawer enables and runs a cycle.
Symptom: Overtemp / disabled
- Let the bath cool.
- Check the operating temperature setting (enter 100, press RESET; only 30-35 C is valid, e.g. 340 for 34.0 C).
- Verify the actual water temperature against an independent thermometer.
- Replace the temperature sensor or recalibrate if it disagrees.
- Refer for service if the heater runs away with a good sensor.
