Problem Probable Causes Corrective Action
A. Improperly installed filter pan
components.
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.
If using Magnasol filter
assembly, verify that O-ring is
present and in good condition on
filter screen fitting.
Filter pump runs,
but oil return is very
slow and bubbling
oil occurs.
B. Attempting to filter with oil that
is not hot enough.
B. In order to properly filter, the
oil or shortening should be at
or near 350ºF (177ºC). At
temperatures lower than this,
the oil 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 is at or
near frying temperature before
draining oil into filter pan.
