My hova bator 1602n is starting to screw up. and I have eggs coming on Monday. It is going through big temp swings. I added a fan to it so it's a forced air incubator. The temp is set up to 99.5 f. It goes to 100 f then down to 97 f. Please help. I have checked the wafer and it rises fine but I don't know. What could it be? Thank you
I'm not an expert on incubators, but it could possibly be the temperature of the room the incubator is in. The room should have a constant temperature and with winter coming, it may be that the cold temperature outdoors and the heating devices indoors are causing temperature swings.
Yep, I agree...that or the fan you added is blowing on the thermostat, causing it to kick on to get back up to 100.... Have you put a second thermometer elsewhere in the 'Bator to check for consistent temps?
that's a normal temp swing for a wafer type thermostat. adding mass to the incubator will help control the swing. if it's full of eggs you don't need anything additional but while setting it up and tweaking a few bottles of water serve the purpose. a water bottle is also helpful if you don't have a full set of eggs. what you want is to have the swing average around your desired temp of 99.5. with your 3 degree swing that would be 98-101, that will give you an internal egg temp of pretty close to 99.5
