What to do if my Fisher Scientific 6845 Laboratory Equipment shows 'EEE' on the display?
If the alarm LED is also lit, allow the incubator to cool to the set point. If the alarm LED is not on, check the thermocouple connections at the rear of the temperature controller. If the thermocouple is OK, replace the control.
How to fix a Fisher Scientific 6845 that is not heating?
First, ensure the set temperature is not less than the actual temperature. If not, replace the control thermocouple. Also, tighten connections at the terminal strip and/or heater. Check the heater resistance against the schematic and replace if necessary. Finally, replace the controller.
What to do if my Fisher Scientific 6845 incubator temperature is erratically high?
If the incubator temperature is erratically high, the control thermocouple or the control board may be defective and require replacement.
Why is the alarm LED on and the control higher than the set temperature on my Fisher Scientific 6845 Laboratory Equipment?
This can happen if the set temperature has been changed to a value less than the actual temperature minus the alarm limit. Wait for the actual temperature to cool to the set temperature, specifically to set plus 3°, and the LED should go out and the EEE alarm display will return to normal operation. If this doesn't work, the controller or solid state relay/safety relay may be defective and require replacement.
