Selector; Thermostat; Relay Board Led's - Viking RDSOE306SS Service Manual

Service Diagnostics and Procedures
Relay boards (cont.)
The tables show the operating characteristics of the selector and thermostat
positions. The selector and thermostat are potentiometers (variable resistors)
whose resistance varies per user selections. The selected resistance informs the
board of the user's selections. All values are approximate.

Selector

Resistance checks are made on the selector wire harness with the selector
wire harness disconnected from the board at location P14 and thermostat
disconnected. The harness is connected to P14 for voltage checks.
