Your micro switch is underneath the metal front cover, you have to get down on your belly and on the left side and then the right side next to the foot is a short Philips screw take them out! Then remove the front panel, on the top right you will see a micro switch with a little tiny plastic stick (sometimes there are red) pushing it in should reset the heater ! If you can not push it in ? The other switch is gone and you can contact Dimplex direct and order a new micro thermostat switch ! They are easy to replace, but make sure the electric is totally turned of ! The mains to turn off is maybe necessary if you Storage Heater is on a economy 7 Deal ! Blessings wolfy
