If anyone comes across this and is looking for a spring for the BOV900BSS Breville Smart Oven Air Fryer Pro I found the strangest place that may have it in stock near you locally (Advance Auto Parts) Dorman - Help Extension Spring - Length 5-6 In. and one of the springs in the set worked for me albeit a bit little too much tension (door snaps a bit when closing maybe because its brand new)... Chose to go this route b/c wasn't sure if the spring that they have online for the BOV800 fits the BOV900BSS but it looks like it would. https://shop.advanceautoparts.com/p/dorm...-help-extension-spring-length-5-6-in.-o.d.-1-8-7-16-in.-w.d.-.020-.060-in.-59001/5013054-P?searchTerm=spring
