Verify 120V power at the connection of the panel to the circuit at the junction box in the wall (for hardwired connections), or at the outlet (for plug-in connections). Each Ember heater has a built-in safety switch that turns off the heating element automatically if it overheats. By unplugging or disconnecting the unit and waiting for about 10 to 15 minutes, the safety switch will reset automatically and the unit will be operational again.
