NOTES:
1. Values in the table are nominal.
Tolerance is +5/-10%.
2. Resistance values (ohms) are @ room
temperature.
3. There are 3 elements per firebar, 6
elements per tank.
1. Remove element head cover as outlined under
COVERS AND PANELS in REMOVAL AND
REPLACEMENT OF PARTS.
Heating elements must remain submerged
in shortening while performing this test or damage
may occur.
2. Access heating element lead wire connections
at wire nuts.
3. Re-connect power, turn power switch on and
set cooking control to call for heat.
4. Measure voltage at heating element
connections and verify against data plate
voltage.
A. If voltage is incorrect, see ALL MODELS
under TROUBLESHOOTING.
B. If voltage is correct, check current draw
(amps) through the heating element lead
wires. See table for proper values.
NOTE: This method is preferred over a
resistance check when a clamp on type amp
meter is available.
1) If current draw is correct then heating
element is functioning properly.
2) If current draw is not correct, turn
power switch off and disconnect
power to the machine.
a. Install a replacement heating
element.
b. Proceed to last step.

Turn power switch off and disconnect
power to the machine.
Remove wire nuts from heating
element lead wire connections and
separate lead wires.
Check resistance (ohms).
