Arrived at location on 5/9/22 - Turned on and pressed reset switch. Display does not turn on. Removed side panels to rotisserie and vent hood. Turned on. No power from power supply to the display. No power to the power supply. Checked vent hood. Air switch is closed and sending power to the relay which sends power to the power supply. Checked outgoing power from the relay. No power.

Display on as well. Started. Heating ok. 15 amps per leg. Heated to temp. Set timer. Timed down and alarm sounded. Back in service.
