7.3.1 Replacing the Interface Board
1.
Remove the contactor box lid and unplug the wiring harnesses from the front and back of the
interface board.
2.
Remove the nuts in each corner of the interface board and slide the board off its mounting studs.
3.
Verify that the spacers are in place on the studs, then position the replacement board on the studs
and re-install the nuts removed in step 2.
4.
Reconnect the wiring harnesses and replace the lid to complete the procedure.
7.3.2 Replacing Other Contactor Box Components
1.
Unplug the control cable from the front of the contactor box. Remove the door magnet and drain
elbow. Remove the screw that secures the box in place and pull the box from the cabinet to the
extent that the wiring allows. If necessary, disconnect the wiring connectors at the rear of the
box to allow the box to be removed completely from the cabinet.
2.
Disconnect the wiring from the component, being sure to make a note or sketch of the wiring
connections. Dismount the component to be replaced and install the new component, being sure
that any required spacers, insulation, washers, etc. are in place.
3.
Reconnect the wiring disconnected in step 2, referring to your notes and the wiring diagram on
the fryer door to ensure that the connections are properly made. Also, verify that no other wiring
was disconnected accidentally during the replacement process.
4.
Reposition the contactor box in the cabinet and secure in place with the screw removed in step 1.
Reinstall the door magnet, drain elbow, and door to complete the procedure.
7.4
Replacing a Temperature Probe or High-Limit Thermostat
1.
Disconnect the fryer from the electrical power supply and drain the frypot into the drain pan
provided with the fryer or other appropriate container.
2.
Remove the contactor box (see step 1 of section 7.3.2 above). Remove the nuts securing the
fryer to the deck and reposition it to gain access to the rear of the fryer.
3.
Remove the screws that secure the element housing and back panel to the fryer and remove the
element housing and back panel to expose the element assembly and rear of the frypot.
4.
Locate connector C7 and disconnect it. Using a pin pusher (Frymaster P/N
), push out
the red and white leads if replacing the temperature probe, or the black leads if replacing the
high-limit thermostat.
5.
If replacing a temperature probe
, cut the metal wire tie securing the probe to the element,
remove the screw securing the probe bracket to the element assembly, and slide the bracket off
the probe (see illustration on following page). Pull the probe leads out of the hole in the element
assembly and remove the probe from the fryer. Thread the leads of the replacement probe
through the hole in the element assembly, position the replacement probe in the element bracket,
and reattach the element bracket to the assembly. Secure the upper portion of the probe with a
replacement metal wire tie.
