Display shows Er07; grill will not power up fully or reboots when starting the igniter.

Safety first: Unplug the grill from the wall outlet before inspecting any electrical components.

• Check outlet and extension cords: Plug another appliance into the same outlet to verify proper voltage. Avoid using long or undersized extension cords with Enders pellet grills.
• Inspect power cord: Examine the grill's power cord for cuts, kinks, or burn marks. Replace the cord if damaged.
• Access power module: Remove the control panel or rear service panel to locate the internal power supply (if separate from the main board). Check for loose connectors, discoloration, or burnt smell.
• Tighten connections: Ensure all spade terminals and plug connectors on the power input and output of the supply are fully seated.
• Test under load: If you have a multimeter and are qualified to work around live voltage, measure the DC output of the power supply when the igniter turns on. A large voltage drop indicates a weak supply.
• Replace faulty power supply: Install a compatible Enders power supply module or control board assembly as designed for your model. Secure all wiring and strain reliefs.

If Er07 persists with a known-good power source and supply, a shorted igniter, fan, or auger motor may be overloading the system and should be tested individually.
