New. Please HELP! :) Is it my responsibility?

[Sophia L.]

I have property in Stockbridge, GA.  I don't provide washer and dryer, but I do provide hookups.  My lease contract states that the tenant is responsible for the appliances.  I was just informed that the exhaust pipe for the dryer is clogged and the tenant wants me to fix it.  As far as I know dryer exhaust pipes get clogged up because people don't remove lint from the lint tray.  Am I responsible to fix it?  If it happened for a different reason, am I responsible for fixing it, given what my contract says?  Will appreciate any thoughts. Thanks.
