part number 819-5432. To order both the card set and the Operator’s Manual, use part number 819-
5569. To order both the card set and the Service Manual, use part number 819-5625.
6.2 Troubleshooting
This section provides an easy reference guide to some of the common problems that may occur during
the operation of this equipment. The troubleshooting guides that follow are intended to help correct,
or at least accurately diagnose, problems with this equipment. Although the chapter covers the most
common problems reported, you may encounter problems that are not covered. In such instances, the
Frymaster Technical Services staff will make every effort to help you identify and resolve the
problem.
When troubleshooting a problem, always use a process of elimination starting with the simplest
solution and working through to the most complex. Never overlook the obvious – anyone can forget
to plug in a cord or fail to close a valve completely. Most importantly, always try to establish a clear
idea of why a problem has occurred. Part of any corrective action involves taking steps to ensure that
it doesn’t happen again. If a controller malfunctions because of a poor connection, check all other
connections, too. If a fuse continues to blow, find out why. Always keep in mind that failure of a
small component may often be indicative of potential failure or incorrect functioning of a more
important component or system.
Before calling a service agent or the Frymaster HOTLINE (1-800-24FRYER):
•
Verify that electrical cords are securely plugged in.
•
Verify that circuit breakers are on.
•
Verify that frypot drain valves are fully closed.
DANGER
Never attempt to move a fryer containing hot cooking oil or to transfer hot cooking oil
from one container to another.
DANGER
Use extreme care when testing electrical circuits. Live circuits will be exposed.
WARNING
Inspection, testing, and repair of electrical equipment should be performed only by
qualified service personnel. The equipment should be unplugged when servicing,
except when electrical tests are required.
