Ceramic hob heating radiant surface element & wire Limiter testing


It easy to test the elements on these but the switches need temperature to operate.

On single element version there will be 2 terminal to the element of double there will be 3, 2 incoming single and the common will be the terminal where both element terminal into one connection on  triple element there will be four connection 3 incoming and one common.

here is a double element for comparison to below single i test on.

To test element find the common terminal on and test between each incoming for continuity it does not really matter about ohms reading as long as it looks healthy for an electric element 10-30 oms.

Here i get continuity and good healthy reading for an electrical element of 26.5 ohms

Here is the switch for the element and the hot light ( Warning indicator )




This is just  thermostatically controlled set of switches on controls the cycling on and off of the heating element the other switches the heat or hot warning indicator lamp on when it reaches a certain temperature.

they can be wired different but the terminal of the switch are usually 

1a to 2a and 1b to 2b in one of below photo configurations.
