We're actually discussing the exact fault in another thread.

The sensor actually isn't faulty. It just reprograms itself into thermostat mode randomly. And when that happens, there's no way to program it out of thermostat mode without redesigning the empeg motherboard completely around it.

So you could send your player into empeg and have them replace the chip, only to have the new temp sensor flip into thermostat mode a week later.
