My suggestion is you contact Thor and request their assistance with the repair. Also, familiarize yourself with the 2 attempt or 21 day rule and the official notification process which should be addressed in the warranty. Right now they have had one attempt. You attempting a repair could negate their first attempt and could possibly result in a "void warranty" claim.
Again, just a suggestion.
