What to do if pressing a button on CSZ Medical Equipment does nothing?
If pressing a button on your CSZ Medical Equipment does nothing, the blue ribbon cable might be disconnected from the control board, so correct the connection to the control board. Alternatively, the control panel may be defective and require replacement.
What does the red 'Power Failure/Caution' LED on my CSZ MICRO-TEMP LT 749 mean?
If the red “Power Failure/Caution” LED is illuminated on your CSZ Medical Equipment, it could be due to the water being too hot. In this case, check the pad connections and wait a few minutes for the water temperature to decrease. If the display alternates between flashing “HL” and the actual water temperature, turn the unit off, allow it to cool, and then service is required.
Why does the pump run but my CSZ Medical Equipment will not heat?
If the pump in your CSZ Medical Equipment is running but the unit isn't heating, the heater might be defective and require replacement. Also, if the temperature is more than 1°C over the set point, check the pad connections and wait a few minutes for the water temperature to decrease. Finally, improper connections to the control board can cause this issue; make sure the connections are correct.
Why is my CSZ MICRO-TEMP LT 749 Medical Equipment making audible indicator sounds?
Several issues can trigger audible indicators on your CSZ Medical Equipment. If the temperature readout is 111°F / 44°C or higher, the unit has reached a high limit; turn it off and allow it to cool. A power failure can also cause this, so restore power to the unit. Ensure the unit is on a level surface, as tilting can trigger the alarm. Check pad connections and allow water temperature to decrease if the temperature is more than 1°C over the set point. If a water level sensor fault is indicated, turn the unit OFF and make repairs based on the display message. If the water temperature sensor, membrane keypad, or microprocessor is defective, service is required.
What to do if CSZ MICRO-TEMP LT 749 turns on but will not pump?
If your CSZ Medical Equipment turns on but the pump isn't working, the issue might be due to low water in the reservoir. Try adding more water to the reservoir. Another possibility is that the unit is tilted, which can prevent the pump from functioning correctly. Make sure to place the unit on a level surface.
Why is the Low Water Caution light on my CSZ MICRO-TEMP LT 749?
If the 'Low Water Caution' light is illuminated on your CSZ Medical Equipment, it indicates a problem with the water level. First, ensure the reservoir has enough water; if the water level is too low, add more water. Check the water level sensor wire connection to the control board, ensuring it's properly connected to the J3 position. If the issue persists, the water level sensor may be defective and require replacement. Also, a lack of conductivity in the reservoir can cause this issue; add two (2) ounces of Propylene Glycol as instructed in Section 4-2.2 to improve conductivity.
