I want to preface this emailed response I received from Harris Farms with the fact that it was information originally given to a lady that couldn’t get her incubator to turn at all. Some information may be applicable or none.
Two possible reasons cause this issue:
1) customer didn’t operate correctly
this customer said “the turner doesn't respond when I press the + or - once”, she need to press the + and - at that same time instead of only press + or only press -
2) cold room temperature casue egg tuner motor ’s inside motor oil viscosity increase when in this case sometimes will prevent the motor from rolling smoothly
the solution is put the incubator in a room with temp not lower than 70F and plug the incubator into power to run for 6~8 hours to warm the inside egg turner, after that, motor can rolling smoothly.
So please tell this customer to following below steps:
1) ensure the romm temperature where the incubator located not lower than 70F
2) ensure the egg turner plug being pushed fully home in the socket located on the back of the top cover
3) close the incubator (do not remove the incubator top part from the bottom) and then plug the incubator into power to run for 6~8 hours
4) then test run the egg turner by press the “+” and ”-“ once at the same time (not just press “+” or “-“, you need to press these two buttons at the same time, and if you operate correctly, will have feedback sound “BEEP…..”)
Each time you press + and - to test run the egg turner, the egg turner will run for 5 seconds; in normal working condition, the egg turner will run for 5 seconds every 60 minutes to turn eggs around 180 degrees.
