Return/exchange policies are lies. Defective parts.
I strongly suggest you avoid trouble by not buying parts from General Appliance Parts for the 3 reasons below, but mostly because their return and exchange policies before sale are different than those after sale. This conclusion comes from comparing the policies stated on their web site to those in an email from someone named "Amanda M" after I contacted the company for a return authorization for a defective part. Buy instead from one of the many truthful/reliable suppliers/marketplaces out there. My qualifications: I'm a DIYer who for 45 years has been fixing my family's appliances (refrigerators, oven, microwave, dishwasher, washing machine, dryer), and am also an electrical engineer.
1. Before sale: Their policy says parts can be returned for a refund minus a restocking fee which varies from 15% to 50% depending on whether the part still looks new and whether it's being returned for an exchange. Defective parts can be exchanged for new if you provide the appliance's model and serial number. After sale: You'll be told their return policy says installed parts only get a 50% refund (it doesn't), and be lectured about how you could have screwed up the installation, or something else on your appliance is broken, and only licensed techs know what they're doing. And exchanges are only made on defective installed parts if you belong to a "service company".
2. Since they offer their lowest restocking fee if returned parts look new and can be resold, this logically implies, unless they test every returned part, some of the parts they're selling were returned as defective. And since the parts they sell are largely 3rd party knockoffs, you're only asking for trouble.
3. Their website and customer service are not available on weekends, citing religious reasons. I don't judge, but I question any religion that says it's okay to lie to customers to make a few extra dollars.
