A clothes dryer is mechanically simpler than many appliances, which often makes repairs economical-especially when the failure is a small safety or wear component. Consumer Reports lists dryers around the low-teens in expected service life; using 13 years keeps this dataset conservative but realistic.
For an LG dryer, repairs under the threshold (belt, rollers, fuse, sensor) are typically worthwhile unless the unit is very old or has multiple issues. If the dryer has chronic overheating, repeated fuse trips, or a costly motor/control-board diagnosis, replacement becomes more appealing because safety and downtime risks rise.
The replacement price reflects a common mainstream electric dryer listing at a major retailer; venting upgrades, stacking kits, and delivery/installation can increase total cost.
