Hopefully someone can help. I just bought a used 1502. At first everything was working great, then I started getting an alarm code for not being able to read the outside temp. Does anyone have a tip or trick to try and remedy the situation before I spend more to order a new part? Is reading the outside temp that important? Thanks for the help.
I wish I could help you and am waiting to see if someone posts a fix. My cabinet is an older one I have had for many years. It doesn't have an outside temperature sensor. I would think as long as your incubator maintains the proper temperature inside it should be ok, but I really don't know.
