Good instinct. If the fans run but it won't cool, the compressor probably isn't starting. The Control Module 640178 on the compressor is the most common cause, and it's in stock. Before buying, confirm you have a solid 12V at the module while the fridge is calling for cooling, and check the module's LED for a flash code. Also feel the compressor to see if it's running at all. If it runs but still doesn't cool, that's a sealed-system problem, not the module. See our error codes page, or contact our Tech Support service.
