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.
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.
