Arrived at location on 1/12/23 - Spoke with customer and they would like the left thermostat replaced on the range griddle. Shut breakers off to unit and opened control panel. Had to remove bullnose to lift griddle to gain access to thermostat. Removed old thermostat and installed new one provided by customer. Reinstalled bullnose and control panels. Powered unit on and tested griddle functions. Griddle heats and cycles as should. Okay.
