HAAS® Alarm 107 — EMERGENCY OFF
Part of: our HAAS® alarm reference · covering 60 of the most common alarms.
What it means
E-stop has been pressed somewhere — pendant, control panel, or a tool setter / probe stop. The machine has dropped power to drives.
Common causes
- E-stop button pressed (or stuck/sticky)
- Probe or tool setter triggered the stop chain
- An interlock door is open
- A loose wire in the E-stop circuit
What to check first
- Check every E-stop button is released (twist to release)
- Check all doors are properly closed and the latches working
- If the alarm persists with everything reset, it's likely an interlock switch
Prevention
Regular preventative maintenance — clean cabinet, working lube, sensible cutting parameters, and a habit of checking offsets before running — prevents most alarms before they happen.
If you’re still stuck
If you’ve worked through the checks above and the alarm hasn’t cleared — or if it cleared and came back — that’s the point to call. Persistent alarms after a reset usually mean a real component fault, and pushing through them risks turning a simple repair into a bigger one.

A note on this guide. Alarm wording and numbering can vary by HAAS® machine model and software revision. The descriptions here are written in plain English to help you understand what the machine is reporting and what to check first — they’re not a substitute for the official HAAS® operator manual or for a qualified service engineer’s diagnosis. Always confirm the exact alarm message on your screen and consult your machine’s documentation before attempting any repair.
