I am sure I am making you crazy.

I changed my frige convert incubator around. I have the thermostat in the center it is not a on off.I have a fan and water bottles on the door.Here is the prob.When I put the Fluker on a middle shelf I get a constent 88.4 when I move it to the bottom it goes much lower.It is a mini frige and I don't understand why the big difference.any ideas?
Thanks again! Mike.

how are you heating it if your using heat tape try running more on the bottom. on mine i used 3" tape a single line down both side and they both went all the way across the bottom. so there was like 6 inches wide of tape on bottom

I just moved the thermostat probe closer to the bottom to see if that will help.I am using flexwatt.If moving the probe doesn't help I will add more Flexwatt.
Thanks!Mike.

I am using a wine fridge for mine. I use 4 inch heat tape starting about a 1/3 of the way down across the bottom and back up the other side and end it even with the other side. If you move the probe down it will make the top hotter. I would rather incubate at 88 than 91 or 92. I would look more at the heat. Oh and my fan is up top blowing down.

My fan is high but is not blowing down it is blowing straight.Also I just added more flexwatt.So we will see.
Thanks!Mike

yeah,have it blowing straight down,or diagonal

in mine, i have 2 fans. one blowing up and one blowing down both in the middle level of the bator. you need to circulate the air. that is why you temps are different. moving the probe is only going to make your top shelves higher. remember, heat rises. i put all my heat on the bottom with the fans blowing it around.

i would add a fan and move the heat towards the bottom.

Try pointing the fan up so that it moves the hot air on top down and around.

i use 2 fans 1 at top left and 1 at bottom right to create a circular air flow.

This is the best I can get.Middle 89.2 bottom 87.6 I added more flexwatt and moved the fans.Using a temp gun the bottles of water are 90.0 I have as much flexwatt at the bottom as I do the top.
Thanks!Mike.
