After three years of using the G5 and now G6 I had my first Dexcom Transmitter failure last night. Two long rather different sounding alert beeps woke me up and when I looked at the app on my phone it said “Session Ended” and underneath a click-thru link that said “I have a new transmitter.” After going through the prompts about serial numbers on the click-thru link it just took me back to the first window. Closed down blue tooth and then started it up again but that didn’t fix it. Called Dexcom tech support and they started an order to replace both my transmitter and the sensor I was wearing. The tech didn’t ask a lot of questions. The transmitter was started on 09/30 and the sensor was just a day old. Dexcom wants my transmitter returned.
The Dexcom phone tech did a pretty good job not answering all my questions about why it failed but I’m in no way implying that this isn’t any more than my transmitter being unexpectedly bad. Just publishing this as an FYI in case anyone else has a similar experience.
