Of four incubators I own, three need adjusting but the worst is only 2 degrees.Yeah I checked and I would have to drop the incubator thermostat to 96 in order for the other one to drop to around 99.5 I checked the fridge and doesn’t seem to read the right temp
Do you have a meat thermometer you could try checking in there? That little one seems sporadic. Maybe leave it in the fridge for 15 minutes or so to see.
