Possible Causes

How to Fix / Troubleshooting
Safety first: Turn OFF and unplug the machine. Allow it to cool before touching internal components.
Steps to resolve ALARM 14:
- Check installation environment: Ensure the machine has adequate clearance on all sides and is not installed in a closed cabinet without ventilation.
- Inspect ventilation openings: Clean any dust or debris from vents and grills around the electronics compartment.
- Verify cooling fan operation (if present): With the machine powered (for qualified users), check that any internal fans spin when the machine heats. Replace the fan if it does not run or is noisy and slow.
- Inspect temperature sensor: Some models use a small sensor near the control board to monitor ambient temperature. Check wiring and replace the sensor if it reads incorrectly.
- Re-test: After cleaning and replacing any failed components, power the machine and monitor internal temperature. If ALARM 14 recurs, the control board may be misreading or misregulating; contact a technician.
