A big box retailer sold me the wrong LP conversion kit for my brand new gas dryer. Their online tool claimed the kit was compatible with the dryer I purchased (bought them together). It was impossible to get a parts diagram from either the manufacturer or the retailer to verify what was claimed, and I mistakenly trusted them.
After learning I had the wrong kit, I angrily searched internet appliance repair forums for stories like mine (turns out I wasn't alone) and found a recommendation for AppliancePartPros.
AppliancePartPros had the correct part number, complete with a current parts diagram and the old LP conversion kit listed as "replaced by" followed by the correct kit SKU. Absolutely insane that Maytag/Whirlpool wants people to struggle to find the information needed to modify, service, or repair your stuff.
In the future for my appliance needs I will order here, my order arrived within 3 days with detailed instructions but most importantly it was actually the part I needed!
