I have two hovabator fan incubators which both work fine for me as I,m on small stand alone solar power and hence need the low wattage incubators.
one has recently started creeping up about 4 degrees celcius after the heating shuts off at 37.
the heat element is not coming back on, the outside temp at the moment is max 29 and if I turn the thermostat down to compensate the temp gets too low but still does its creeping up.
the other one is beside it on the bench and works fine. difference of only 36.8 to 37.5.
I have fitted a new heat ring, a new fan and cleaned the micro switch and it still does it
?????
any ideas
regards

The wafer appears to be working OK and have swapped it with the other incubator to make sure.
Hasn't made any difference.

It sounds like the heat from the element is not being transferred to the air quickly enough and thus continues to raise the temperature after the thermostat switches off. I would be looking at any obstruction to the air flow and/or heat being directly absorbed by some solid component close to the element.

I have found the problem after reading the replys and a good think.
the replacement heat ring is a smaller diameter and slightly smaller in length and was about 20mm closer to the metal wafer thermostat housing so I,ve reshaped it carefully away from the body and temp now sits as it should.
thought I was going senile there for a while.
thanks for your help.
Bruce
