We've had the microphone go in and out. Resetting doesn't work anymore, so I tore into it tonight (wish I would've seen this guide before, didn't think the connector glue would be as strong as it was). I did not make it past the first circuit board. What I couldn't figure out is where the microphone is.
I believe it's the enclosure with cord coming out with the antenna, soldered straight into the board. It could also be the temperature sensor. Thankfully pulling it apart and reassembling it got the microphone working again, but you can bet your bottom dollar it'll go out again.
Thanks for the guide, it was very helpful seeing what else is in there.
