What to do if the display screen on GE IC3645SH7R354D2 Controller is blank?
- D
  Douglas RiveraAug 16, 2025
  If the display screen on your GE Controller's Dash Display or Handset is blank, it could be due to several reasons. First, ensure that the key switch is closed, as the absence of positive or negative control voltage can cause this issue. Another potential cause is an open circuit between control card Plug Y and the Dash Display or Handset; check for any open circuits or loose connections. Finally, the Dash Display or Handset itself may be defective, requiring replacement.

What to do if GE IC3645SH7R354D2 won't operate when accelerator is depressed before directional switch?
- G
  Gregory JohnstonAug 28, 2025
  If your GE Controller will not operate and the accelerator pedal is depressed before closing the forward or reverse directional switch, the status code will disappear when the directional switch is closed or when the accelerator pedal is released. If the issue persists, a defective directional switch may be the cause. Check the forward or reverse switch to ensure it closes when the direction is selected.

Why is there reduced power to traction motor in GE IC3645SH7R354D2 Controller?
- C
  cortezjosephAug 31, 2025
  If your GE Controller exhibits reduced or no power to the traction motor within the control range, it could be in thermal cut back. Allow the control to cool down, and the status code should disappear. If the problem persists, the control itself may be defective, requiring replacement.

How to troubleshoot segments not illuminating on GE Controller display?
- R
  Robert MeyerSep 3, 2025
  If the segments on your GE Controller's Dash Display and/or Handset do not illuminate, it could be due to no input voltage reaching the control card or the display unit. Check for voltage between P1 and battery negative (Power Terminal “NEG”). Also, check for voltage between P2 and control negative.

What to do if line contactor opens and closes on GE IC3645SH7R354D2?
- I
  Ian WareSep 12, 2025
  If the line contactor on your GE Controller opens and closes intermittently, and can only be reset by cycling the key switch, there are a few potential causes. A discharged battery could be the culprit, so check its state of charge. Also, ensure that the wire connection at P1 is tight, as a loose connection there can cause this issue. If neither of those resolves the problem, the controller itself may be defective and require replacement.

- T
  Tracy PeckSep 12, 2025
  If the line contactor opens and closes on your GE Controller, and can only be closed by opening and closing the key switch, and this is caused by defective control, the suggested solution is to replace the controller unit.
