Wires Normally closed
DOOR SWITCH
Check switch between “COM” (common) and “NO” (normally open) contacts, insure switch closes approximately 3 to 4
inches before door closes.
BLOWER FAN
Blower fan will rotate clockwise and should have a 5/8“ gap between it and the back wall of the can.
AUTO/BYPASS SWITCH
The Auto / Bypass and Energy switch are located below the controls behind a pull down access panel
Auto/Bypass switch Normally in “OFF”
. The “ON” position will interrupt
power to the computer and allow use of the back-up
thermostat.
Energy switch Normally in “HIGH”
for 11 kW heats. “LOW” WILL
PROVIDE 8.25 kW heat. Not provided on Steam
convection ovens.
