Last winter, my daughter had almost the exact same issues. Omnipod replaced most of the pods for us, and I quickly learned how to pull the insulin back OUT of the pod to use in another one.
Several tips that OmniPod offered, and they work, are:
Make sure you have a humidifier. Static electricity can cause issues with both the PDM and the pods. Static Electricity can zap any pump, so that is not just an OmniPod issue. I have noticed this winter we have not had as many issues, since I got a good humidifier, and keep it running.
2nd, put a dryer sheet (Bounce, etc) in your PDM case. This helps eliminate the static buildup, also.
Also, if you are getting your pods shipped monthly, ask that they put on the package to set inside the garage, or between the doors, because the cold seems to affect the pods even though they say they can handle down to 15 degrees. They can put that on the shipping order, regardless of where you get your pods from.
If where you work is dry, and you have the capability of doing so, put a coffee cup of water on a candle warmer plate. This helps keep the area you work moist. If you can't afford a humidifier, try that at home, or put a big pan of water on the stove and let it simmer for a bit (just don't let the pan boil dry!)
