Hello everyone, I'm new to BYC.... Unfortunately my first post is going to be a question I have regarding a Marsh Roll-X incubator I own. It won't maintain a constant heat. It runs up to 96 / 97 degrees then it backs off and sits around 85 degrees. Any idea what could be causing this? I assume I need to replace a part or two... I grabbed the below pictures from a previous thread... Mine looks almost identical to this incubator, the only difference is my incubator does not have the Thermo Wafer Thermostat off to the side (note the bottom picture w/ the round wafer on the lower right hand side).
