Hello Chris,
I don't know if you still need the manual, as I can see that you originally posted this message in January 2020.
Anyway, I have a model from the same range, an RLE1096H, and also need to reverse the door.
After spending hours since last week looking for one, then contacting Frigidaire US as there was no UK website, then being led by them to Electrolux UK, then requesting the manual by email on Electrolux's website, then calling Electrolux, then being told by Electrolux UK that they would not be able to send me the manual as they are working from home, and the manual is on the main server (as it is an old model), but that if I searched on Espares I would find it, then realising that the Espares manual is not a manual but just diagrams of parts, but noting from this information that the fridge was made by Gorenje, then calling Electrolux again and being told the same thing again, as well as being told that they would probably reopen some time in July, and that, most likely, no one would respond to my email request (no one has to date), then spending hours online looking for the manual or something similar again, also using the fact that the products were made by Gorenje in my searches, then realising, while searching today, that one of the links to another manual came from a website that was called something like partners.gorenje, then visiting the website, going on support, then manuals, then searching 'RLE', I have finally, eventually, managed to find the manual for your fridge, RLE1099A, which is in the same range as mine, and which contains the door reversal instructions. :))
Well, after that long list :), the web address is https://www.gorenje.co.uk/support/manuals. Search 'RLE', and your fridge will come up (https://partners.gorenje.com/fts/GetDigitDoc.aspx?sifra=665705&jezik=en&tipVsebine=1&docName=141868en.pdf).
After how long it took me, I just thought that I would reply to your message, just in case.
Please do let me know how you fare, or if you have all ready reversed the door, either way.
