ER1 occurs if the signal from the grill temperature probe fails.
This can occur for a number of reasons:
- Temperature probe wiring connection on the back of controller is loose
- Temperature probe cable is damaged
- Temperature probe plug is loose
- Grill temperature probe is faulty
Z Grills temperature probe inside the grill
Check cable plug
Use a screwdriver to gently lift the cable out from between the hopper and grill, and check to ensure the plug is tight
Test if ER1 has been fixed
- Plug the grill back into the power supply
- Turn the grill power switch on. If there is still an issue, ER1 will be displayed on the display.
- If ER1 is still displayed, continue onto the next step.
Check the wiring connection
Check the temperature sensor probe connection to the controller:
- Unplug the grill from the power
- Remove the two screws that secure the controller in place
- Gently pull out the controller enough to locate the two thin white wires in the small green or blue terminal block.
- Check to ensure they are both tightly in place (gently tug on them)
Test if ER1 has been fixed
- Plug the grill back into the power supply
- Turn the grill power switch on. If there is still an issue, ER1 will be displayed on the display, then you need to contact the Support Team for a new temperature probe.
