SALAMANDER ELECTRIC BROILER - SERVICE PROCEDURES AND ADJUSTMENTS
1) If both measured values are
approximately the same as listed in the
machine information table, then
heating elements are functioning
properly.
2) If one or both of the measured values
do not agree with the values listed in
the machine information table, then
heating element is malfunctioning.
Turn broiler control switches OFF.
Disconnect the
electrical power to the machine and
follow lockout / tagout procedures.
Fig. 15
HEATING ELEMENTS TEST
a. Install a replacement heating
element then proceed to step 2.
C. If unable to check current draw, a resistance
check (ohms) at heating element terminals
may indicate a malfunctioning element.
Disconnect the
electrical power to the machine and
follow lockout / tagout procedures.
1) Remove lead wires from the heating
element and check resistance. See
machine information tables under
resistance values at room

are Infinite load switches; On 480V broilers, the two
heat controls are 4 Position 3 Heat switches.

heating element is still suspect,
see TROUBLESHOOTING.
5. Check broiler for proper operation.
A. If voltage is incorrect, see
B. If voltage is correct, check current draw
(amps) through the heating element lead
wires at the X and Z phases on the outlet
side of the broiler terminal block. The X
phase value is the current draw for the left
element and the Z phase value is the current
draw for the right element.
See machine information tables under
values and the appropriate 208/240V -
connections.
NOTE: Checking current draw is the preferred
method over a resistance check when a clamp on type
amp meter is available.
