Heating Element Test - Vulcan-Hart ERO15 Service Manual

ER SERIES ELECTRIC FRYERS - SERVICE PROCEDURES AND ADJUSTMENTS
A. If necessary, adjust as outlined below.
4. When basket is in the up position, the bottom
of the basket should be out of the shortening.
When basket is in the down position, the
bottom of the basket should clear the crumb
screen and the product should be submerged.
A. To adjust, remove basket arm from lift
shaft, loosen stop nut and turn height
adjustment bolt to raise or lower basket
arm as required. Both baskets should be
same height.
B. Re-tighten stop nut when complete.
NOTE: If adjustment is to low, when the basket is
lowered, it will disengage from basket arm.

1. Remove element head cover as outlined under
COVERS AND PANELS in REMOVAL AND
REPLACEMENT OF PARTS.
CAUTION: 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.
C. If unable to check current draw, a
resistance check may indicate a
malfunctioning element. See table for
proper values.
1) Turn power switch off and disconnect
power to the machine.
2) Remove wire nuts from heating
element lead wire connections and
separate lead wires.
3) Check resistance (ohms).
5. Check for proper operation.
