Frigidaire wall oven GLEB30S9FSC burned rid to able element

[gowerdavid]

So my wife mentioned that it was taking too long for the oven to heat up... I figured the element was bad, but checked continuity, fine...checked thermal switch, fine, checked power, fine...so I open the control board and find that the yellow wires to the bake element is burned...my question is, does it make sense to replace the control unit since it would seem some kind of short burned this one and I don't want to pay $250, have to finagle a new connector to replace the burned one, and then have it fry another board....what would do this???? Could I possibly solder the wires directly and see if maybe it works??? This would save me money...which right now would be very good...really wonder what could have caused this though...only thing I can think of is that we had a ceramic pan break and pirces of this could have gotten under the cover and contacted the element, but i wouldnt think that would cause a short like this....links to pics below.

I doubt a short caused this failure, corrosion, etc causes the resistance to increase at the point from the wire terminal to its connection on the board and then it heats up, increases the resistance and heats even more until it melts the solder connection on the board. If it's your own unit and your fire insurance is paid up, you could try resoldering the connection but it'll fail pretty quickly as the board has already been cooked once. Try looking for a new board on eBay or other sources. Sears shows a list price of about $185 for the board.

Too common on Frigidaire bake connections. Replace board, cut bake terminal out of molex connector (small hacksaw), Splice new high temp terminal replacing burnt terminal.

Sorry for the previous; getting old and my connections are starting to heat up.

Giving fatherly advice, I would replace the board and the connector harness.   We don't really know the extent of damage to the wire harness due to excessive heat.

If you don't want to or can't run the entire harness to the element connectors, you can splice the existing wire harness, making sure to cut off at least 6 to 8 in.(from the old connector), and use porcelain only, wire nuts.

Best to run the new harness I know, but I have done hundreds of these in my time and had no failures due to the splice.  It has to be clean and solid making sure no wire strands are lost in the stripping process, as this will cause over heating problems and potential harness failure.  

It is always best to do it the right way and usually ends up costing less in the long run.
