Heating grid lines versus heating grid terminals: who is right?

• A. Heating grid lines can be replaced
• B. Heating grid terminals can be repaired
• C. Both statements are correct
• D. Neither statement is correct

Answer: (B)

The key idea is what parts of a heating element are designed to be serviced. The grid lines are the actual resistive heating path embedded in the element. They’re thin, fixed, and usually not repairable in the field—any damage to those lines generally means replacing the entire heating grid assembly. The heating grid terminals, however, are the external connection points where power enters. Those points are designed to be accessible for maintenance: you can clean them, tighten connections, or replace the terminal hardware or terminal block. Because these terminals are serviceable while the heating lines are not, the statement that heating grid terminals can be repaired is the correct one.
