I have a GE model # JGBP32GEL flashing F1 every few seconds. The only way to stop it is to unplug it for a while. When I plug it back in it will start up again in a few hours. My question is what is the message indicating and what part needs to be replaced?

p.s. the stove is about 18 years old

Thanks in advance

Update: It means you need to replace the whole ELECTRONIC PAD, about $200. Just buy a new stove!!
