  If your Vallox control panel and ventilation unit aren't working, it might be due to a loss of power or the safety switch not being engaged. Check the fuse in the fuse box and the glass tube fuse in the unit. Also, ensure the safety switch catch is fully touching the safety switch. If it can be turned on after pressing the safety switch, ensure that the safety switch catch is touching the safety switch.
