Interface Boards
The electric fryer interface board is similar
to interface boards on the H.E. gas fryers.
LED indicators aid in troubleshooting, and
the board acts as a common junction for
the fryer's electrical components. Unlike
the gas version, the electric board includes
an additional relay for the latching circuit.
All the wire connections for this circuit are
located on the front side of the board. The
table below provides ten system checks.
The meter reading must agree with the
values in the table.
