When necessary, technicians disassemble the appliance to examine its parts, using the appropriate hand and power tools. They use special devices such as ammeters, voltmeters, digital logic testers, pressure gauges, manometers, and pipe-threading tools to check and repair electric, electronic and gas systems. After determining the problem, technicians estimate the time and cost of repair. Then, with the customer's approval, they make the necessary adjustments, replace worn or defective parts, and install new ones. They may cut, thread, and connect pipe to a feederline.
Repairers also test for gas and microwave leaks.
As part of their job, repairers keep records of parts used and time spent on each call and compute the total charge. They also may answer customers' questions or complaints about the appliances and demonstrate their proper use and care.
