Rtd Sensor; Rack Support - Viking VDSC548T Series Service Manual

Service Diagnostics and Procedures–Disassembly
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power to unit using power
switch before servicing. Wires removed during disassembly must be replaced on proper terminals to insure
correct earth ground and polarization. After servicing, reconnect power using power switch.

RTD Sensor

The oven sensor is a Resistance Temperature
Detector (RTD) that has a positive temperature
coefficient. The sensor measures changes in
resistance and communicates this to the control
board.
To access RTD:
1. Remove oven door (see Door Removal section,
page 107).
2. Remove screws that attach the sensor to the
back of the oven liner.
3. Pull the sensor from the liner until the sensor
connector protrudes into the oven cavity.
Note: The connector will not come through the
hole in the oven liner.
4. Apply side pressure to the sensor connector
to secure the connector against the opening in
the oven liner.
5. While maintaining side pressure on the
connector, disconnect the old sensor and
connect the new sensor.
Note: When reinstalling the oven sensor, it may be
helpful to insert a small screwdriver or awl into the
connector and push the wiring and connector into
place.
