I have a eurotech dryer model # EDC 158. Where can I purchase a latch assembly for it?

Try going to repair clinic at repairclinic.com or parts pros.com

Try unplugging it for a minute or 2 to reset the unit

Clean out your vent before calling a repair man.

Try Eurotech, Italy or Turkey. They are the manufacturers and are generally helpful. Have your model and serial numbers ready.

Go to searspartsdirect.com and type your model number in the “Search by Model Number” block. The part can be located under the “Door and Latch Parts heading as item number 7 (part number 8181700). If you need step-by-step instructions on how to replace, just follow the link below:
