Gaymar T/Pump Classic TP650
Gaymar · Model T/Pump Classic TP650
Cooling setting delivers 50°F (10°C) therapy For warming therapy, two selections are available: Low (100°F/38°C) or High (107°F/42°C) Three-layer safety system with dual temperature sensors, dual microprocessors and a mechanical thermostat to ensure patient safety Illuminated LED control panel, comfortable handle, built in hose and cord storage and translucent water reservoir all were designed for ease of use at home or in any health care setting Uses tap water (and ice cubes if cooling) Optional T/Pump Stand available for convenient placement and ease of transport (comes with storage basket for pads and accessories)
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.
No or low water flow to the pad
HighSymptoms: Pad stays cool, weak circulation.
Root cause: Kinked or occluded hoses, low reservoir level, or a worn pump impeller.
Does not reach the selected set point
HighSymptoms: Water not warming (or cooling) to 10 / 38 / 42 C, therapy ineffective.
Root cause: Heater element, a tripped thermal cut-off, or a temperature-sensor fault.
Over-temperature shutdown / mechanical thermostat trip
MediumSymptoms: Unit stops, over-temp indication.
Root cause: Sensor or control fault driving the heater high, or a failed mechanical thermostat in the 3-layer safety system.
Reservoir or connector leak
LowSymptoms: Water pooling, reservoir level drops between uses.
Root cause: Cracked reservoir or worn quick-connect couplings.

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: Pad not warming / weak flow
- Check hoses and clamps for kinks or occlusions.
- Top the reservoir to the fill line - never run it dry.
- Confirm the pad is below the unit and not folded tightly.
- Feel for pump flow at the outlet; replace the pump if weak.
- Run the annual Functional Check with a calibrated thermometer to verify temperature and flow.
Symptom: Does not reach set point / over-temp trip
- Toggle the set points to confirm the keypad responds.
- With a filled reservoir, verify the heater draws current and the water warms.
- Check the dual sensors and the mechanical thermostat.
- Replace the failed heater or sensor.
- Test the over-temperature safety circuit per the Functional Check.
