Common ventilation issues vary depending on your ventilation system, so we've separated out the different types of ventilation systems below and the checklist to run through to diagnose and fix your ventilation issue.
1) Check if you have a Wrong Setting
Is your fan spinning? If not, then go to your touchscreen – Tools – Settings – Ventilation and switch to “Onboard Fan“
2) Check for a Jammed Fan
Is your fan spinning? If not, your fan could be jammed or clogged. Unplug your laser, remove your laser tube guard and visually check for anything that could impeded the fan from spinning.
3) Damaged/Faulty Error
If none of these fix the error, then your ventilation sensor is damaged/faulty and your laser needs to be serviced.
1) Check if Your System is On
Double check that your booster fan/filtration system is powered on.
2) Make Sure your Duct is Connected
Double check that your ducts haven’t come loose/are connected on both ends
3) Check if Your Filtration System is Strong Enough
Fan/filtration system isn’t pulling at a high enough speed. This could be caused by blocked or dirty filters/fan or, in new systems, cardboard blocking the filters inside the filtration system
4) Check for Blocked Ducts
Check to see if your ducts are blocked and need to be replaced
5) Sensor issue
If none of these fix the error, then your ventilation sensor is damaged/faulty and your laser needs to be serviced.
