DEAN 18UE COOL ZONE SERIES ELECTRIC FRYERS
CHAPTER 8: TROUBLESHOOTING
8.1 Introduction
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/Dean Technical Service 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 the
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/Dean HOTLINE [phone]):
• Verify that electrical cords are plugged in and that circuit breakers are on.
• Verify that fry vessel drain valves are fully closed.
DANGER
Never attempt to move a fryer containing hot cooking oil/shortening or to transfer
hot cooking oil/shortening 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.
DANGER
NEVER use open flame to melt solidified shortening-blockage in the filtration
system. Open flame increases the chance for extreme fire hazard and operator
injury.
