You need to approach each problem carefully and systematically. Carefully—never do anything that can put you, other people, or property in danger. Wear appropriate Personal Protective Equipment and protect your work area with drop cloths, newspaper or builder’s paper. Use insulated screwdrivers and avoid working on live electrical circuits. Do not press reset buttons without first making sure that there is not a fire or an oil buildup in the combustion chamber. Systematically—the best Service Technicians develop standard troubleshooting routines. They go from step to step until they find and correct the cause of the problem. A systematic approach starts with logic—looking for the obvious solution and then trying to narrow down the problem. Start with the easy—if the heating system is not working, check that all electrical switches are turned on and that there is enough oil in the tank before you start disassembling the oilburner. Most importantly, NEVER assume anything. Don’t assume that the reset was only pressed once; don’t assume that the last service technician installed the correct nozzle; don’t assume that your dispatcher told you the correct reason for the call and don’t assume that because a customer says they have plenty of oil that their tank isn’t empty. An example of a systematic troubleshooting routine: Step 1. Information gathering: 15-4 Service Procedures Effective troubleshooting starts before you arrive at the customer’s home. When your dispatcher gives you the call, try to get important data such as: • What problem did the customer report? • When was the last oil delivery? • When was the last tune-up? • When was the last service call, and what was done? When you arrive at the customer’s home, listen to what the customer says and ask questions to clarify the situation. Depending on the type of trouble, you may want to ask if any work has been done recently that might have caused the situation, such as other tradesmen working on the electric or plumbing, or if a chimney sweep has just been performed. Ask if they have pressed the reset button, how many times and what happened after it was pressed. Once you think you understand exactly what the problem is, proceed to the appliance area and on your way, check the electrical switch and oil tank gauge.
