It depends on the severity of the damage and how much it will cost to repair. Generally, it's better to repair an appliance if it's still under warranty, but if the damage is too severe or if the cost of repair is close to the cost of replacement, then it might be wiser to just buy a new one. One thing to keep in mind is that most appliances have a lifespan and once they reach a certain age, they're not worth repairing anymore. So if your dryer is more than 10 years old, it might be time for a new one even if it doesn't seem severely damaged.

It usually costs around $100 to have a dryer repaired. However, the cost may vary depending on the severity of the problem and the parts that need to be replaced.
