I remind myself of a terrible experience I had several years ago when I brought my desktop computer in from a cold car, plugged it in and fried the mother board! I found out the hard way that it is always a good idea to allow an electronic part like control boards, pressure switches, televisions, laptops, etc. to warm up to room temperature before applying power. If you bring anything in from the cold outdoors into a warm home, condensation (water) will form on the part. We all know that water is a conductor. We can see why so many electronic parts can get destroyed if we do not allow them to warm up before applying power. I would strongly suggest that we allow the electronic parts and devices to sit for a couple of hours for warm up. This allows time for the water condensation to evaporate before applying power. I hope this will save you and others from problems.
