The average dryer repair takes about an hour, according to The Family Handyman. Basic household tools and a continuity tester or multimeter are the only requirements for a homeowner to fix about 90 percent of dryer problems. Extra time may be needed to locate replacement parts.
The Family Handyman gives clear instructions about basic dryer repair, such as dryer disassembly, door switches, thumping noises, heat problems and belt replacement. It also includes a quick fix for dryer doors that don't stay shut. Tools required for typical repairs include a set of socket wrenches, a four-in-one screwdriver, a putty knife and a shop vacuum.
