Problem
Filter pump runs,
but oil return is very
slow and bubbling
oil comes out of the
Power Shower.
Power Shower not
spraying properly.
6.3 Replacing the Controller or Controller Wiring Harness
1. Disconnect the fryer from the electrical supply, remove the two screws in the upper corners of
the control panel and swing the panel open from the top, allowing it to rest on its hinge tabs.
2. Disconnect the wiring harness from the back of the controller. If replacing the harness,
disconnect it from the interface board. If replacing the controller, disconnect the ground wire
and remove the controller by lifting it from the hinge slots in the control panel frame.
3. Reverse the procedure to install a new controller or wiring harness.
Probable Causes

Corrective Action
A. If using filter paper or pad
configuration, verify that filter
screen is in bottom of pan with
paper or pad on top of screen.
Verify that o-rings are present
and in good condition on filter
pan connection fitting.
B. In order to properly filter, the
oil or shortening should be at
or near 350ºF (177ºC). At
temperatures lower than this,
the oil/shortening becomes too
thick to pass through the filter
medium easily, resulting in
much slower oil return and
eventual overheating of the
filter pump motor. Make sure
oil/shortening is at or near
frying temperature before
draining oil into filter pan.
A. Verify that the gasket is present
and in good condition.
B. If the Power Shower is not
cleaned on a routine basis,
sediment will eventually block
the small holes around the edges
of the frame. Also, when using
solid shortening, if the Power
Shower is not allowed to drain
completely, the shortening will
solidify in the holes and may fill
the frame. Completely drain the
Power Shower after each
filtering and clean regularly in
accordance with the instructions
in Chapter 5 of this manual.
