Canaan Avalon A1246 Stopped working | Bitcointalksearch.org

Happy New Year to everybody! Wish you a lot of happiness, health and prosperity!

I have 2 x Avalon Miners A1246. They work in a really rough environment (I had no where else to put them) where it has a lot of dust / straw particles and lately due to winter a lot of humidity. One of them, after an Internet blackout failed to come back on. What I suspect happened is that that particular night had a lot of humidity, the miner did not have Internet connection and therefore it run cold (no hashing) for 3-4 hours. The fans were working therefore the humidity was entering normally. I cracked the miner open today and the hash boards are in a really bad condition. Dust everywhere, sticking around all the circuit components throughout the boards. I cleaned all the connections and components on the top of the hash board where the cable connects to the board but nothing changed. What do you suggest I do? My next option is to remove the heat sinks clean and put thermal paste again but I am not sure how I should preform this kind of cleaning. Would a contact cleaner spray be okay? I attach my error log for consideration. I will try and take pictures as well. I would appreciate if there is a way to contact you through a private message. If you prefer I can start a different thread. Thanks
