Why is the display flashing 1999 on my Binder KMF-240 Laboratory Equipment?
- T
  Terry MillerSep 23, 2025
  If the display is flashing 1999 or -1999 or 9999 on your Binder Laboratory Equipment, it could be due to a sensor rupture between the sensor and controller or a defective Pt 100 sensor, so contact BINDER service. It also could be a short-circuit. It also could be an initialization problem due to turning on the chamber too early. Observe a delay time of about 30s between turning the chamber Off and On again.

Why am I getting wrong temperature alarms on my Binder Laboratory Equipment?
- D
  Dawn BakerAug 25, 2025
  If you experience wrong temperature alarms or disturbance of temperature accuracy with your Binder Laboratory Equipment, it may be because the temperature unit has been changed to °F. Set the temperature unit back to °C.

How to fix a Binder Laboratory Equipment chamber that is heating permanently?
- C
  Corey LeeAug 26, 2025
  If the chamber of your Binder Laboratory Equipment is heating permanently and the set-point is not maintained, it could be due to a defective controller, in which case you should contact BINDER service. Alternatively, the controller might not be well adjusted, or the adjustment interval may have been exceeded. In this case, calibrate and adjust the controller.

  jameshillAug 27, 2025
  If your Binder Laboratory Equipment chamber isn’t heating up, it could be due to a defective Pt 100 sensor, in which case you should contact BINDER service. It could also be due to a defective heating element or a defective semiconductor relay.

Why does my Binder KMF-240 have humidity fluctuation?
- J
  Joshua FoxAug 27, 2025
  If you're experiencing humidity fluctuation and the control accuracy of ± 3 % r.F. is not reached in your Binder Laboratory Equipment, it could be due to a defective door gasket; replace the door gasket. Also, opening the door very frequently can cause this issue; try to open the doors less frequently.

Why doesn’t the “RESET” button cancel the alarm on my Binder KMF-240?
- E
  Eric DavisSep 16, 2025
  If the “RESET” button does not cancel the notifying or alarm indication on your Binder Laboratory Equipment, it means that the cause of disturbance has not been removed correctly. Remove the cause of disturbance. If the “RESET” button still does not cancel the indication, contact BINDER service.

Why is the program duration longer than programmed on my Binder Laboratory Equipment?
- P
  Peggy TaylorSep 13, 2025
  If the program duration is longer than programmed in your Binder Laboratory Equipment, it's likely because tolerances have been programmed. For rapid transition phases, do NOT program tolerance limits in order to permit maximum heating, refrigerating, or humidification speed.

Why does my Binder KMF-240 Laboratory Equipment program stop one section too early?
- W
  Wendy MckeeSep 15, 2025
  If the program stops one section too early on your Binder Laboratory Equipment, it indicates that the program line is incomplete. When programming, define the end value of the desired cycle by adding an additional section with a section time of at least one second.

Why is there icing at the evaporator plates in my Binder KMF-240?
- T
  Thomas HuynhSep 5, 2025
  If you notice icing at the evaporator plates in your Binder Laboratory Equipment, it's likely because the set-point was set too long below the ambient temperature. To resolve this, defrost the unit.

What to do if mechanical safety device class 3.1 responds in my Binder KMF-240?
- E
  Elizabeth PattersonSep 3, 2025
  If the mechanical safety device class 3.1 responds in your Binder Laboratory Equipment (with option safety device class 3.3), it might be because the limit temperature has been reached. Check the setting of the temperature set-point and of safety device class 3.1. If appropriate, select a suitable limit value. Also, too much external heat load could be the cause, so reduce the heat load. If the controller is defective, contact BINDER service.
