so the icemaker was not brand-new, just the fridge? What is the model of the fridge and what kind of icemaker did you install?
what is the model # XXXXX i can look it up. Thanks
1. on the icemaker make sure that the metal bail arm is in the down position.
2. if you want to advance the icemaker to make sure it works you can make a jumper wire, (1 piece of wire stripped on both ends) and you remove the cover of the icemaker and you will see some holes (carefully) you would put on end of the jumper in the one labled "H" and other in "T". That will advance the icemaker.
3. after the icemaker is done going around, did it drop ice? did it refill with water?
4. there could be airbuild up in the line.
Let me know if i can be more assistance.
