Home Forums General Discussion Technical Questions Northern 3200 Panic Stopping

2006 Era time bomb, stopping mid flight independent of direction, load, position, etc. Stops for 2-3 seconds then takes off again.
Anyone with a clear set of prints handy? Trying to trace low voltage across DEN coil (21/24 DC).

Replace the high voltage board

Check your communication signals from PPU in the controller. I had a similar issue it ended up being the faulty motherboard on top of the elevator.
