Product review (1 stars): FIRE RISK!!! (see 4/2018 update)
We purchased this unit and were pretty happy with it overall, it was competitively priced. However, it broke 2 months out of warranty. That's when I found out how terrible LG customer support is. When you email them, you cannot follow your thread, but have to start all over again each time. The phone people cannot help much, and when I asked to speak to a manager, was disconnected, and never got a call back. I did my own problem determination, using the paper guide on the back of the unit, and this indicated the board was bad - one of the most expensive items!!

Come to find out this is a common problem with many LG electric stoves! Service plan costs $400 - about the cost of the  board, so after trying to get LG to replace for free or partial, we give up as it's close to Thanksgiving and have company arriving. LG contracts with a local company, who in turn subcontracts with another company. They guy arrives and fixes it in 15 minutes ... the connector to the board was bad from the factory (his assessment), he snips wire and puts on a new connector. So I just paid $400 for a .10 part!! Technician says LG have a lot of board problems.

We tried to get LG to compensate us, but customer support refers us to warranty, who refer us back to customer support. After about ten phone calls I gave up - maybe that was their intent all along. LG used to be a good brand, but based on this product, and my interactions with them, we could not recommend any LG brand.

Update 4/2018 - broke again w F9 error, this time a main wire into the connector block (where main power comes into unit) melted and broke off! Looks like it got hot enough to melt some plastic - see photos!  LG should recall these ranges! I'm concerned it could catch fire! Shouldn't there be a fuse that should protect this from occurring?
