I normally work on pinball machine circuit boards, but a family member mailed me this board. The relay G8P-1C4P burned up bad by one leg. What normally causes this? This seems to be what powers the heating elements in the oven. Is this just the relay failing or something else shorted that caused relay on the PCB to burn. I can replace all the scorched looking parts, but is there likely to be other problems? Here is some pics of the EOC https://picasaweb.google...09484127/OvenPanelRepair

Cold have been a bad solder joint at that leg.

Cannot say.

You could but it would be a gamble.
Also looks like tracks are blown so you would have to run jumper wires.
When they blew out, it probably took out some of the solid state parts.
Manufactures do not publish board schematics so you will not be able to check the board or try to figure out other possible problems with it.
Personally I would say that the board is done. There is just too much damage. |
