Belshaw Brothers 616BT B Electrical Components, Testing the Continuity of the Toggle Switch

B Electrical Components

This appendix explains how to test the continuity of electrical components in your fryer. These include the toggle switch and the thermostat.

The appendix also contains a document by the Robertshaw Controls Company, the maker of the thermostat we use in the 618L, 624, and 634. It explains how to check, adjust, and recalibrate the thermostat.

Testing the Continuity of the Toggle Switch

WARNING

To avoid the possibility of electric shock, disconnect the machine from the power source before testing.

1.Disconnect the machine from the power source.

2.Disconnect the terminal wires from the switch.

3.Obtain a continuity tester or a volt-ohm meter. If neither of these instruments is available, make a continuity tester using a battery and a bulb. See Figure B-1.

4.Connect the wires of the continuity tester to the switch terminals, as shown in Figure B- 1, and test the switch in the ON and OFF positions. The switch should show continuity only when in the ON position.
