The cost of replacement parts for a dryer ranges between $35 and $100, as of 2015, depending on the part. Whether the dryer is electric or gas also affects the cost.
Typical replacement parts needed for broken dryers are the heating element or ignition coil. These vary in cost but should not run more than $100. If a professional replaces the part, labor and a diagnosis charge may add up to $80 more.
Thermostats and fuses can also be the cause of dryer problems. The dryer's manual should have a wiring diagram to help test these parts. Replacing the fuse or thermostat costs between $10 and $50.
