Troubleshooting Procedures

Multi−Position Switch

Continuity Test

1.Remove all wires connected to the control.

2.Turn control to OFF. Check for continuity between each contact (1−1a, 2−2a, 3−3a, ect.) except contacts 7−7a. If continuity is found between any contacts, the switch has failed and must be replaced.

3.There is a diode across contacts 7−7a. With the

control turned to OFF, check continuity across this contact. Ohmmeter must be set at 10 KΩ setting to check diode measurement. There should be no continuity one direction and continuity the other direction. If this indication is not obtained, switch has failed and must be replaced.

		1b	2b

4.Use the matrix above to determine if the switch is closing the proper contacts at a particular setting. If switch does not match the matrix the switch has failed and must be replaced.

5.The switch thermostat is between terminals 5 and 1a, Replace the switch if an open exists between these terminals.

NOTE: The halogen element being controlled by the multi−position switch will vary in intensity and not cycle on and off unless the limiter switch opens.
