Why is there condensation at the walls of the inner chamber in my Binder KMF-720?
- S
  schneidercourtneySep 8, 2025
  If you observe condensation at the walls of the inner chamber of your Binder Laboratory Equipment, it could be due to a combination of temperature/humidity values not being in the optimum range; select a combination of temperature/humidity values in the optimum range. Alternatively, the set-point may have been too long below ambient temperature, causing icing in the preheating chamber; defrost the unit.

Why is the refrigerating performance low in my Binder Laboratory Equipment?

  megan26Sep 7, 2025
  If you are experiencing low or no refrigerating performance in your Binder Laboratory Equipment, it could be due to several reasons. The ambient temperature might be higher than 25 °C / 77 °F, in which case you should select a cooler place of installation. It could also be that the combination of temperature/humidity values is not in the optimum range; select a combination of temperature/humidity values in the optimum range. If the compressor is not turned on, contact BINDER service. Also, too much external heat load could be the cause, so reduce heat load.

  If your Binder Laboratory Equipment unit isn't heating up when turned on and the safety controller responds, it could be due to the limit temperature being reached. The safety controller might be set too low. To fix this, let the chamber cool down and hit the RESET button of the MB1 controller. If appropriate, select a suitable limit value. If the safety controller is defective, contact BINDER service.

What to do if mechanical safety device class 3.2 responds in my Binder KMF-720 Laboratory Equipment?
- S
  scottdylanSep 4, 2025
  If the mechanical safety device class 3.2 responds in your Binder Laboratory Equipment (with option safety device class 3.3), it could be because the limit temperature has been reached. Check the setting of the temperature set-point and of safety device class 3.2. If appropriate, select a suitable limit value. If the controller or safety device is defective, contact BINDER service.

Why my Binder Laboratory Equipment has no function?
- S
  Sarah RamirezSep 2, 2025
  If your Binder Laboratory Equipment unit has no function at all, start by checking the connection to the power supply. Also, verify that the power supply voltage matches the unit's requirement of 115V or 230V. Inspect the unit fuse and replace it if necessary. If the fuse responds again, contact BINDER service. A defective controller may also cause this issue, requiring you to contact BINDER service.

What to do if my Binder KMF-720 has no unit function and a dark display?
- C
  Chloe CampbellAug 31, 2025
  If your Binder Laboratory Equipment unit shows no function with a dark display, it could be due to the display mode being in “Standby”. To resolve this, simply press any controller key. Alternatively, the main power switch might be turned off; in that case, turn on the main power switch.

Why am I getting a humidity alarm message when operating without humidity on my Binder KMF-720 Laboratory Equipment?
- J
  Jimmy HartAug 30, 2025
  If you receive a humidity alarm message when operating without humidity (humidity switch (4) OFF) on your Binder Laboratory Equipment, it means that the humidity set-point is set to a value > 0% r.F. In Manual Mode: Enter a humidity set-point 0% r.H. In Program Mode: Enter a humidity subprogram with humidity set-point 0% r.H.

Why does my Binder Laboratory Equipment have humidity fluctuation?
- J
  Joseph Curry DDSAug 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.
