Dryer Vent Testing Kit
This Dryer Vent Testing Kit is for 29 inch dryers with a top mounted lint screen, and is meant to ensure your dryer's venting system is running properly. Use the plastic card, hang inside your dryer drum, then run your dryer three times without any clothes. If the card stays in place, the venting and dryer need to be cleaned out.This is a universal accessory that can be used across several models; check to see if your model number is compatible. Replacing this accessory will not require tools, disassembly of the appliance or repair experience.
