You know... your dryer may still need cleaning- run the lint screen under the faucet and see if water goes through it. You should be washing the lint screen every 3 months with soap. I have to scrub mine in order to get all of the stuff off. If the water can't get through, it can actually be a fire hazard AND your dryer is running harder in order to get the clothes done. This is the number one thing you can do in order to keep your dryer around longer. (A tip from my brother- the enviromental safety engineer.)
I bought it to mop my hardwood floors with, then switched to something else.
