Working on a Escape 36dv Heat n Glo fireplace.

This has been an ongoing issue. Found the large control module to be defective since it was melted.

Put a new control in, 2 weeks later, its melted again.

Heat n Glo says there is an "upgrade kit" to prevent this from happening.

Does anyone have a picture or some sort of manual for this upgrade kit? Has anyone experienced the same issue and have resolved it using this kit.

Any information for this unit will be greatly appreciated!!!
Thanks in advance!
