Delfield 2194809 Replacement Cabinet Temperature Sensor

Delfield 2194809 Cabinet Temperature Sensor

Commercial replacement part. Delfield 2194809 provides temperature information to a compatible refrigeration controller. The correct sensor and connector arrangement let the control monitor the intended location in the cabinet.

When to inspect or replace this part

Inspect the sensor and harness when the controller displays a probe fault, reports an implausible temperature or fails to respond consistently. Loose connections, damaged insulation, moisture at a connector and controller faults should be checked before a sensor is replaced.

Specifications

Compatibility and ordering checks

A model-specific compatibility list has not been confirmed for this reference. Match the original part number and verify the equipment's serial-specific parts list before ordering.

Match the original part number, controller type, connector, lead length and sensing location. Cabinet-air and evaporator sensors are not automatically interchangeable, even when their plugs look similar.

Installation and service

Disconnect power before handling wiring. A qualified technician should route the lead away from moving components, restore the original sensor position and compare the controller reading with an independent thermometer after service.
