How to fix dark displays on Fisher Scientific Laboratory Equipment?
- L
  Larry RamirezAug 22, 2025
  If the displays on your Fisher Scientific Laboratory Equipment remain dark, there could be several reasons. First, check the fuse or circuit breaker to ensure there's a mains voltage supply; replace or switch it on if necessary. A faulty mains cord or instrument socket could also be the cause, so inspect and replace any defective parts. The unit fuse or fuses on the main board might be defective, requiring replacement; if the fuse blows again, investigate further. Also, check the connectors on the CPU, indication board, and connecting leads for a low voltage supply issue. Finally, an interrupted program could be the culprit; in this case, insert the valid NV-RAM and ensure it's correctly seated in the socket.

Why can't I open the lid of my Fisher Scientific Laboratory Equipment, and it shows error “E-17“?
- S
  Stephanie BarkerAug 26, 2025
  If the lid of your Fisher Scientific Laboratory Equipment cannot be opened with the key at a standstill and displays "E-17", several issues could be the cause. The lid solenoid might not be getting enough voltage, so refer to the manual opening cord in the bottom plate. The PTC resistor may have released; wait two minutes and press the key again. A faulty driving or triac circuit could also be the problem, which would require replacing the complete main board. Alternatively, the lid coil could be faulty, necessitating replacement of the entire lid lock device. Ensure the lid is correctly locked by pushing it centrally into the lock and pressing the key again. Finally, the lid might be de-adjusted, so re-adjust it centrally.

How to troubleshoot drive noises and poor separation in Fisher Scientific Laboratory Equipment?
- W
  webershaneAug 29, 2025
  If your Fisher Scientific Laboratory Equipment drive is making noises and you're not getting good separation results, consider these possibilities: * The motor rubber mounts may be worn out; replace them (at least every three years). * The motor bearings might be failing; replace the entire motor. * There could be a defective terminal connection, faulty lead, or motor winding. Check the voltage on the motor terminal and winding resistances, referring to the test points on the boards. * The power electronics might be faulty; replace the main board.

Why does „OPEn“ appear when the lid is closed on my Fisher Scientific Laboratory Equipment?
- K
  Karl HammondAug 30, 2025
  If "OPEn" appears in the speed display of your Fisher Scientific Laboratory Equipment even when the lid is supposedly closed, it indicates that the 15V low voltage supply for the frequency converter (via the lid switches and motor over-temperature switch) is interrupted at standstill. Check the leads and connectors to the micro switch, and if the micro switch is faulty, replace the entire lid lock device. Also, check the motor over-temperature switch and leads for continuity, replacing any faulty parts (including the motor if necessary). Another possibility is that the 15V low voltage supply on the main board is defective, requiring replacement of the main board.

Why are all display elements briefly illuminated on my Fisher Scientific Laboratory Equipment?
- C
  Crystal Torres DDSSep 1, 2025
  If all display elements on your Fisher Scientific Laboratory Equipment are briefly illuminated, it could be due to a CPU program reset caused by EMI. Remedy the failure; if the voltage drops often, use a voltage stabilizer. Another cause could be a bad or missing ground connection. Check all ground connections and the ground connection of all boards.

What causes imbalance without “bAL“ message on Fisher Scientific Laboratory Equipment?
- T
  Tyler MccoySep 2, 2025
  If your Fisher Scientific Laboratory Equipment experiences an imbalance but does not display the “bAL“ message, it may be due to the imbalance cut-off not functioning. Check the imbalance switch adjustment. Alternatively, the circuits of the main board may be faulty, requiring replacement of the main board.

What does the „E-02“ message mean on my Fisher Scientific Laboratory Equipment?
- M
  Mark BurnettSep 4, 2025
  If you see an “E-02“ message on your Fisher Scientific Laboratory Equipment, it indicates that the program sequence was disturbed. To resolve this, check all ground connections and tighten any loose screws. Additionally, the message could indicate an internal program error, in which case you should replace the CPU or the main board.

What does the error message „E-04“ mean on Fisher Scientific Laboratory Equipment?
- B
  baileyjohnsonSep 6, 2025
  If your Fisher Scientific Laboratory Equipment displays the error message “E-04“, it indicates a fault in measuring temperature values. Perform a resistance test at ?=20°C: a reading of 100? should display (-1±1)°C, while 120? should display (50±1)°C. If the temperature measurement is faulty, or if there is a defective circuit, replace the main board.

What does the error message „E-06“ mean on Fisher Scientific Laboratory Equipment?
- K
  Kristy StaffordSep 7, 2025
  If your Fisher Scientific Laboratory Equipment displays the error message “E-06“, it could be due to several reasons. Check the data lines and soldering connections, replacing any faulty parts. The CPU might be defective, requiring a CPU exchange. A faulty keyboard could also be the cause, or a faulty main board. In the last two cases replace the main board.

What does the error message „E-07“ mean on Fisher Scientific Laboratory Equipment?
- C
  Crystal BrownSep 9, 2025
  If your Fisher Scientific Laboratory Equipment shows an “E-07“ message, it indicates that the compressor didn’t work. Check the leads, terminals, start relay, capacitor, and the compressor itself. It could also indicate a faulty cooling cycle with refrigerant loss, in this case search for leakage and close it, evacuate and refill with new refrigerant.
