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) [link|https://shop.advanceautoparts.com/p/dorman-help-extension-spring-length-5-6-in-od-1-8-7-16-in-wd-020-060-in-59001/5013054-P|Dorman - Help Extension Spring - Length 5-6 In.|new_window=true] 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.[br]
