Question:
Can I Kasher a clean but not new portable electric stovetop on chol hamoed Pesach? Mine broke and my parents have an extra one
Answer:
Kashering will not do the job, because if you do libul to it, it will get ruined, and hagalah can not be done now, as it will make the pesach pot trief. What can be done is if the burner is indeed very clean, it can be covered with silver foil very well so that no spills can come in contact with the metal aroiund the burner.
