GE JB645RKSS Repair Guide
America’s default electric range — the JB645 shows up in more kitchens than almost any other stove. Radiant glass top, self-clean oven, simple electronic control: its failure list is the standard electric-range trio of elements, sensor, and (post-self-clean) thermal parts.
Common problems & typical repair costs

Tech notes
The classic post-self-clean death (dead oven, locked door) is a thermal fuse and latch check — cheap. Skip self-clean and this range runs 20 years.
