Arrived at location on 3/14/22 - Vulcan steamer is steaming when timer is off. Checked unit over, open door, steam coming out. Removed side panel. Allowed steamer to heat and cycle. Unit is cycling but is blowing steam out when hold thermostat should be keeping water at 195, should not be steaming at this temp. Hold thermostat is cycling too high. Thermostat needs replaced. Will order and return. Returned to location on 3/21/22 - Unit operational upon arrival but steaming even the timer is off - needs a new hold thermostat - dismantle old and replace the hold thermostat - install a new one - test run and observe the unit - unit operational
