Why is my generator failing to stop?
If your diesel generator is failing to stop and keeps running, there are several likely causes to check immediately. First, inspect whether the MCCB breaker is jammed open and needs servicing. Check whether the fuel pump is forcing fuel through without receiving a stop signal, and look for loose wiring inside the control panel. If the generator will not respond, hit the emergency stop button. In most cases, stop/start issues result from missed service intervals or prolonged exposure to adverse weather — both of which are preventable with regular maintenance.
If your diesel generator won’t stop and just keeps running, FIRST check the following suggestions.
- If the breaker is jammed in the OPEN position, arrange for the MCCB to be serviced.
- Is the fuel pump forcing fuel through the generator without receiving a signal to stop? Check the electrical connection when safe to do so.
- Has the control panel stopped working? Look for loose wiring connections inside the panel, ensuring safety at all times.
- HIT the emergency STOP button. This will STOP the generator (unless someone has
disabled the connection). - Then as a priority, call a local generator engineer to investigate the issue.
A generator will only have stop/start issues if:
- You have ignored the manufacturer’s service and maintenance recommendations, or
- You have allowed adverse weather conditions to affect the generator over a lengthy period of time.
- It maybe time to service your generator.
