I'm doing maintenance on 2009 GE Front loader washing machine and ordered replacement drive belt.
The new belt is not OEM, but the printed part number "7PJE 1303" is same as on the old (different font-style and manufacture though). Nevertheless, I'm finding the new belt is slight shorter than old belt, by about 1.5" over ~50" circumference (about 3%).
I'm replacing the belt because it was slipping, but no necessarily because belt was worn. There is definitely issue with door seal/boot that would easily cause belt to slip. The belt felt pretty tight and was not easy to remove from the wheel, and no obvious wear or frays.
Setting aside the fact that the belt felt pretty tight, is it normal for drive belt to inelastically stretch over time (15 years)?
