The board works as listed in used condition, which is great since the existing board wasn’t working any more. A great value at less than 1/5 of a new board.

My daughter’s LG washer took a power bump that fried the motherboard and other parts. No local help, but A-Z Appliance Parts came through and went above and beyond. I explained what happened, and they quickly replied with exactly what we needed. One-stop shop. Their expertise was solid, real old-school service—no machines, just a person who communicates and knows their stuff. Parts arrived fast, installed easy, and boom—washer worked like new. Highly recommend. Top-notch!!

Fast ship! Wrapped very well, plugged up and worked perfectly!! Great condition! Tremendous value over new, looks just like my existing board! Thank you so much for what you do! Washer has never run better, so easy to remove and install the board, why even consider paying anyone for a 20 min DIY with this part.

Part was just what I needed for my dryer! Seller shipped promptly and arrived as described. Quality used part and was packaged very well. This is a great value buying used over new for these older units. I just had to change the dial for my particular unit, install and we are back to drying our clothes!

Item arrived quickly and was as described in the posting (used, in good condition, fully functional). Packaging was adequate and made sure the item arrived undamaged. Very economic way to fix a washing machine instead of spending $1,000 on a new one! Overall happy and would order again!

Item arrived in excellent packing material to protect the delicate electronics. The item was just as described and it was used however it was very evident the seller refurbished the item with a thorough cleaning and also added electrical protection to sensitive electrical components. The part was an instant fix to my washer machine problem and this purchase has saved me nearly $600 in having a repair man come out to fix the issue. I would definitely recommend purchasing from this seller.
