Jumping icemakers is what we say when we are forcing an icemaker to cycle. This is done by bypassing the thermostat, which is done in various ways depending on the type of icemaker.

ELECTRONIC HEAD ICEMAKERS
If you have an icemaker with an electronic head (icemakers that are in most refrigerators not made by GE), it will have holes that are marked T, V, L, H, M and N. What you want to do is make a jumper wire (just a wire about 4 in. long skinned about ¾ on each end). Now insert one end of your jumper wire in the hole marked T, insert the other end in the hole marked H. Once the jumper wire is in place, the icemaker should start going through the cycle after about 10 seconds or so, you can take the jumper wire out. the icemaker should continue through the cycle.

GE ICEMAKERS MADE BEFORE THE YEAR 2000
On GE icemakers made before the year 2000, you jump the icemaker by pulling on the rake arm until the feeler arm starts to move up. The rake arm is the arm that rakes the ice out when it dumping. The feeler arm is the arm that feels the ice and cuts it out when the ice bin is full. After doing so the Icemaker should continue through the cycle. This icemaker can be found at AppliancePartsPros.com.
Note that this is how you jump all GE icemakers without a switch on the side of the icemaker. No switch indicates it is a mechanical icemaker. Even some newer icemakers are mechanical.
GE ICEMAKERS MADE AFTER THE YEAR 2000
On GE icemakers made after the year 2000, you jump the icemaker by turning it
off for more than 30 seconds. Now turn the icemakers back on and push the feeler
arm in three times within 15 seconds after turning it on. Be sure to only push
it three times because if you push it more it won’t run water in. This icemaker
