Actually cold can affect electronics just as much as heat can. Semiconductors change behaviour with temperature and can behave unpredictably if their operating range is exceeded in either direction. It's not good if your semiconductors quit semiconducting. The major difference is that cold generally does not have long-term effects on the electronics, while heat can actually damage them permanently. -- M.
