Hello Josh. Sorry to hear about your malfunctioning LG. Do you know how old the oven is? Do you know the model number?

Thanks for asking, @HU-16168550092. The oven is about 12-13 years old, and it's model number LRG3093ST.

The replacement controller assembly is part number AGM73590311, but as I mentioned, it's no longer manufactured, and nobody seems to have this part (new or used) in stock.

Though I doubt it, Parts Warehouseclaims to have the part available within 10 days. However that old range (not oven) isn't worth $324. The CR-recommended LG LSGL6335F is $1400 at Best Buy and Home Depot. Want to spend less? The LG LRGL5823S is only $998 at Home Depot though its Baking score was lower.

An alternative is wait for a used or NIB item to come up on eBay ... depends on your patience and how common is the item, and your affinity for keeping the range.

There are services that repair appliance control boards. Membrane touch-button panels are much less common to be handled but I found this on a search. There may be others. They advise contact in advance to confirm a given item can be handled. The Repair Shack

Here's the service manual whose Controller Parts diagram might help you remove the part if you find a replacement or someone to repair it.
