CHAPTER 6: PREVENTIVE MAINTENANCE AND TROUBLESHOOTING

6.1Preventive Maintenance

Preventive Maintenance (PM) procedures are contained in McDonald’s Preventive Maintenance System Maintenance Requirement Cards (MRC) 12, 14, 14A, and 15. The cards are distributed with this manual, but are not an integral part of the manual. A replacement card set may be ordered using 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.

6.2Troubleshooting

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.
