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 this equipment. The troubleshooting guides in this chapter are intended to help you correct, or at least accurately diagnose, problems with the 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. Most importantly, 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. 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.

Some of the troubleshooting actions recommended in this chapter involve removing suspect controllers and substituting controllers that are known to be good, if they are available. Whenever this is indicated, refer to Section 5.3. Refer to Section 5.4 for instructions on replacing fuses in 17EC and 17ECS models.

If the troubleshooting and corrective actions in this chapter do not solve the problem, the problem is probably beyond the scope of most operators to solve and you should call your FASC for assistance. 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.

Before calling a servicer or the Frymaster HOTLINE (1-800-551-8633):

Verify that electrical cords are plugged in and that circuit breakers are on.

Verify that water supply valves are open and that drain valves are fully closed.

DANGER

Hot water can cause severe burns. Never attempt to move a cooker containing hot

water or to transfer hot water from one container to another.

DANGER

Use extreme care when performing electrical circuit tests. Live circuits will be

exposed.

WARNING

Inspection, testing, and repair of electrical components should be performed only by qualified service personnel. The equipment should be unplugged when servicing, except when electrical tests are required.
