Replacing A Vib (Valve Interface Board) Board; Replacing A Rotary Actuator; Control Power Switch; Leakage - Frymaster BIELA14-T Series Service Manual

1.12.3 Replacing a VIB (Valve Interface Board)
Disconnect the fryer from the electrical power supply. Locate the VIB (valve interface board) to be replaced under a
frypot. Mark and unplug the harnesses. The VIB assembly is held in place with one screw (see Figure 27). Remove the
screw and the assembly drops down (see Figure 28) and the tab slides out of the bracket attached to the frypot (see
Figure 29). Reverse steps to reassemble, ensuring that the new VIB assembly slides into the slot in the bracket. Once
complete, CYCLE POWER TO ENTIRE FRYER SYSTEM. See section 1.13 to cycle control power. Check software version
number and if necessary update the software. If a software update is necessary, follow the instructions to update the
software in section 1.15.

1.12.4 Replacing a Rotary Actuator

Disconnect the fryer from the electrical power supply. Locate the actuator to be replaced and mark
and unplug the actuator. The actuators are held in place by two Allen screws (see Figure 30). Loosen
the Allen screws. Remove the actuator from the valve stem. Align the actuator with the valve stem and
attach the new actuator. Tighten the two Allen screws ensuring they are not overtightened, which can
strip out the housing. Reconnect power and test the actuator.
NOTE: Rotary actuators have two different part numbers which are also color coded (blue and black),
which are mirror images of each other that corresponds to their mounting position
.

1.13 Control Power Switch

Figure 30
The control power switch is a rocker switch, located on the front of the left control box
above the USB port (see Figure 31), that controls all power to all the controllers and boards
in the fryer. It is necessary to power cycle all power after replacing any controller or board
and after any setup change. Turn off the switch for thirty (30) seconds when cycling the
control power to ensure power has sufficiently drained from boards.

Leakage

Leakage of the frypot will usually be due to improperly sealed high-limit thermostats, RTD's,
and drain/return fittings. When installed or replaced, each of these components must be
sealed with Loctite ® PST56765 sealant or equivalent to prevent leakage. In very rare cases, a
leak may develop along one of the welded edges of the frypot. When this occurs, the frypot
must be replaced.
Figure 31
If the sides or ends of the frypot are coated with oil, the most probable cause is spillage over
the top of the frypot rather than leakage.
The clamps on the rubber boots that hold the drain tube sections together may loosen over time as the tubes expand
and contract with heating and cooling during use. Also, the boot itself may be damaged. If the section of drain tube
connected to the drain valve is removed for any reason, ensure that its rubber and clamps are in good condition and
properly fitted around the drain tube when it is reinstalled. Also, check to ensure that the drain tube runs downward
from the drain along its entire length and has no low points where oil may accumulate.
