3.
Check the thermocouple for a measurable
resistance (approximately 5 to 10 ohms at room
temperature). If meter reads an overload (OL)
condition (open), or zero ohms (short) replace
the thermocouple and check temperature
controller for proper operation.
HEATING ELEMENTS
1.
Access HEATING ELEMENT as outlined in REMOVAL AND REPLACEMENT OF PARTS.
2.
Measure voltage at heating element terminals and verify it against the data plate voltage.
A.
If voltage is incorrect, find the source of the problem.
3.
If voltage is correct, check current draw (amps) through the heating element lead wires. If current draw is
correct then heating element is ok. See table below for proper values.
NOTE:
Checking current draw is the preferred method over a resistance check when an amp clamp meter is
available.
A.
If current draw is not correct then, replace heating element.
4.
Check for proper operation.

1. Dual voltage elements.
2. Element lengths are staggered to fit the contour of the kettle bottom. Element number 1 is the shortest.
3. 480V elements are connected in Wye configuration for 277V across each element.
NOTE:
Values in table are nominal. Tolerance is ±10 %.
