Henny Penny 581 Programming manual

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
manual.
Before troubleshooting, always recheck the operation pro-
cedures 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.
3. Review all possible causes. Then, one-at-a-time work
through the list of corrections until the problem is solved.
