What does Gardner Denver shutdown 102 drive 1 fault mean?
Short answer: Main motor VFD shutdown. If your Gardner Denver AirSmart controller is showing SHUTDOWN #102 DRIVE 1 FAULT, the controller has logged a specific, documented condition. This page covers what it means, what causes it, what you can safely fix yourself, and when — and why — it takes a technician.
What exactly is the machine telling you?
The variable frequency drive powering the main motor has shut itself down and reported a fault to the controller.
Which machines show this?
Gardner Denver rotary screw compressors fitted with the first-generation AirSmart microprocessor controller — a wide range of oil-injected packages, including VFD-equipped variable-speed units where the controller supervises the drive. The first-generation AirSmart reports problems as numbered codes: SHUTDOWN #1xx and #2xx faults that stop the machine, and ADVISORY #3xx warnings that let it keep running while flagging maintenance. That numbering matters when you search — the later AirSmart G2 dropped the numbers and displays plain-text fault names instead, so a numbered code on the screen tells you that you are on the earlier controller. Shutdowns clear with Stop/Reset once the machine has stopped; advisories acknowledge with the Enter key.
What causes it?
- The main motor VFD tripped on its own internal protection and reported the fault to the AirSmart
- Overheated compressor room or clogged control-box vents cooking the drive
- A one-off power disturbance the drive refused to ride through
- An actual drive failure — the case where it faults again right after reset
Can you fix it yourself?
Sometimes — note the code on the drive's own display, cool and clean the control box vents, and try one reset. If it faults again, stop; this is drive diagnosis, not operator work.
Step by step — what to try, in order:
- Note any fault code shown on the drive display before clearing anything
- Check that the compressor room is not overheated and control box vents are clean
- Press Stop/Reset once the machine has stopped and attempt one restart
When do you need a technician — and why?
VFDs hold a lethal capacitor charge even after power is cut, so opening the drive cabinet to diagnose it is strictly a job for a qualified technician.
If it does come to a service call and you're in Nashville, TN or Birmingham, AL, we maintain independently compiled lists of local companies that service industrial air compressors — real businesses with verified contact information, none of whom paid to be listed.
