I have a customer who has an WP WRX988SIBE00 bottom mount freezer who has had ice build up on the freezer evp only about a 1/4 of the top had ice build up which was hitting the evp fan.
Initial visit found that the main pcb had damage on the back of the pcb - So i ended up replacing main pcb W10807590 along with evp freezer harness that has fan, sensor, bi-meal ect.. W11032800
(orig pic from visit is attached)
about 4-5 weeks later I go back and it has the same ice build up pattern (only top) , hitting the fan assembly but not a thick..
kind of seems like its not going through defrost long enough..
I have checked to make sure nothing was leaking come down from the fresh food section through damper area that leads to the freezer, bi-metal and temp sensor checks out to specs.. no damage on pcb..
Has anyone ran into something similar to this?
Any insight would be greatly appreciate thank you!
