Chapter 15 Service Procedures Chapter 15—Service Procedures 15-3 Introduction The most interesting and challenging part of an Oilheat Service Technician’s job is troubleshooting. Think of all the parts that must work together for a system to function properly; if any one of them becomes defective, the system will malfunction. Your job is like a detective’s— you must figure out what happened, why it happened, how to fix it and how to keep it from happening again. The previous chapters have provided you with an understanding of the operation of the various components of Oilheat systems. This chapter explains how to use that knowledge to repair systems without wasting time or replacing parts that are working properly. Before you get involved with in-depth troubleshooting, remember to check the basics: • Are all the switches on? • Is the fuse blown or circuit breaker tripped? • Is the thermostat set above the room temperature? • Is there oil in the tank? • Is the blower door closed? (There is a switch on many blower doors that prevents the system from operating if it’s not properly closed.) • Is there enough water in the steam or hot water system? • Are the air filters clean? There are many reasons for a customer to require your expertise, among the most common are: • No heat • Insufficient heat • Too much heat • No hot water • Water leak • Oil leak • Odors, smoke or soot • Oil tank and/or piping • Thermostats, controls or electric supply • Heat distribution system • Oilburner components Using an electrical meter Chapter 15 Service Procedures
