All of our items have been tested while installed in the original unit by one of our skilled and knowledgeable technicians. If the item condition is listed as. New- A brand new, unopened item (may be opened for photographs). New (Other)- A new part that may have been installed and never used, or briefly installed and used. Used- An item that has been removed from an older unit, but is still in functional condition. We DO NOT sell parts for trial and error and would much rather see to it that you receive the proper part you need to repair your appliance the first time around. Should you not be able to sort it out on your own, or if you aren’t sure what exactly is wrong with your appliance, you can schedule a virtual service call on our website! “Talk to Eugene” to get to the scheduling page. This is a standard policy among appliance parts dealers. We will figure something out. We have been in the used appliance business for over 15 years, and are a proud member of the Better Business Bureau.
