I checked over the Griddle unit and found multiple wires burnt, right heat selector switch bad, left stat bad and left terminal block needs replaced. The customer has the terminal block but we will need to order other parts and return to repair. All wires for the bottom terminal on left terminal block are zip ties together. The power is off to the unit at this time and I called the manufacturer for part numbers. 7/5/19 Installed parts tested unit, found okay, unit is operating correctly at this time.
