I bought an LG incubator with the egg turner at TSC. (I had another LG but my 4 year old cracked the styrofoam). I bring home the incubator and get it set up....it heats up and runs for about 20 minutes and then quits. No heat, but the little light was still on. I take it back to TSC and exchange it (they were super good about it). Bring the new incubator home and get it set up. It runs for 8 hours at 100, perfect. I put my eggs in at 9am...go back to check it at 3pm and nothing. No heat, it won't do anything. The light won't even come on. What gives?
