How The Midmark M11 Door Switch Works

During the Fill, Heat-Up, & Sterilization Modes... When a cycle is initiated, the PC board monitors the status of the door switch.

If an open door is detected, the cycle will not start.

If the door switch opens during a cycle, the cycle will be terminated and the corresponding error code will appear in the display.

During the Vent, & Drying Modes... The Midmark M11 Door Switch is not monitored


  • When the door is open, the door switch is untripped....the circuit is open (Connection Is Broken)
  • When the door is closed, the door switch is tripped....the circuit is closed (Connection Is Completed)
