FBR18 & FBRA18 SERIES GAS RETHERMALIZERS CHAPTER 5: OPERATOR TROUBLESHOOTING

5.1Introduction

This chapter provides an easy reference guide to the more common problems that may occur during the operation of your equipment. The troubleshooting guides in this chapter are intended to help you correct, or at least accurately diagnose, problems with your equipment. Although the chapter covers the most common problems reported, you may very well encounter a problem not covered. In such instances, the Frymaster Technical Service Department 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 a cord into a receptacle or open the valve on the water supply line. Don’t assume that you are exempt from such occurrences.

Always try to establish a clear idea of why a problem has occurred. Part of your 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 while you’re at it. If a fuse continues to blow, find out why. 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.

Each guide begins with a description of a common problem in a six-sided figure. Simply follow the arrows and answer the questions to determine the corrective action to take. If you have doubts as to the proper action to take, do not hesitate to call the Frymaster Technical Service Department or your local Frymaster Factory Authorized Service Center for assistance.
