Henny Penny 581 User Manual 2

This section provides troubleshooting information in the form
of an easy to read table.

If a problem occurs during the first operation of a new fryer,
recheck the installation per the Installation Section of this

Before troubleshooting, always recheck the operation pro­cedures per Section 3 of this manual.

To isolate a malfunction, proceed as follows:

1. Clearly define the problem (or symptom) and when it
occurs.

2. Locate the problem in the Troubleshooting table.

Section to safely and properly make the checkout and

repair needed.

If maintenance procedures are not followed correctly,
injuries and/or property damage could result.

The following guide requires voltage to be present when troubleshooting the control. When
the guide refers to connecting pins on the power connection, unplug the power connector
from the board and refer to the attached illustration. These are numbered 1 through 9.
Using a strand of #16 gauge wire, connect the pins as numbered in the troubleshooting
guide. Extreme caution must be taken when connecting these pins to avoid control board
damage or electrical shock.

If the power connector is making poor contact onto the board, an error message could be
read, or it might disable other components. When removing connector, look down into power
connector to see if the ramp connectors, inside the power connector, are not flat. If so,
they can be removed from the power connector, and bent back into proper position.
