LG (Mod LWS3081ST /00... F9 error, no heating. Have tested all elements and thermostat per tech sheet. All are to specs. Do not know how to test relays for the individual elements. Need to find out if it is the relay board or the system board. Thanks in advance.

Scratch that last post. The thermostat is bad (open, no continuity). But on further inspection the plastic has melted at one of the leads on the thermostat. What would cause that? I would still like to know how to check relays as well. Again, thanks in advance.

Thats the one. Checked with LG, the thermostat is rated at 25A 180C but the oven has two 20A fuses. I'm thinking the only way to melt the plastic would be excess current or heat. But only one lead shows signs of melting. The lead comes directly from the 20A fuse??? Any ideas? Thanks.

Melted plastic body housings and burnt electrical connections are almost always caused by loose electrical connections. Loose connections make heat. Terminals get loose and sloppy over time and eventually arcing starts occurring. It's the type of stuff that keeps up Master Appliantologists in bidness!

Note that during self clean cycle, surfaces within oven become very hot if built into a tight space - can cause tripping of those as well.
