Hova bator wafers

[angora831]

I am new to using a wafer controlled incubator and have had a new one running for about 6 weeks now. Have used it on a couple of batches. First batch the temp stayed pretty even, but now the temps seem to be up and down and need to be adjusted a few times a day. What is the normal "working life" of these wafers and is this what happens when they start to go bad? Thanks

I have had my 1583 for about 4 months, and the temp almost never moves. I too would wonder if the wafer is going bad. One thing I have noticed is that the temp will fluctuate more if the humidity is low or the bator is not full. If you aren't using the bator with it being filled with eggs, at least put some baggies or jars with water in them, some clean, dry rocks, or something to take up the extra space. And probably would be a good idea to get another wafer to keep on standby, just in case yours is going out
