What to do if my THERMEx Ventilation Hood displays ER03 or error?
- AAlec MolinaAug 20, 2025
If your THERMEx Ventilation Hood displays 'ER03 or' and turns off after 10 seconds, it might be due to constant activation of the sensors, possibly caused by liquids or tools on the control panel. Try cleaning the glass surface. If the problem continues, contact an authorized service center, quoting the error code.
