Ice maker - jumpers to determine what is wrong

I am following the instructions provided earlier to "jump" two holes in the ice maker to determine the problem. Here is my question:

I have followed the steps to "jump" holes "T" and "H" on the ice maker and the "harvest cycle" does not start. I assume by saying to "jump" those tow holes all I need to do is insert a wire into those holes. Can you suggest anything else? I have removed both the emitter and receiver boards and reset the connectors. When the freezer door is opened, the light pulses twice, then a pause and the cycle is repeated. When I depress the receiver flap, the light is on. When the receiver flap is depressed and the light sensor is depressed, the light from the emitter goes out. Is this correct behavior? Bill Fetech

As the previous thread of the conversation regarding your ice maker is not included here, a suggestion I have is to verify some information and troubleshooting tips for ice maker problems in the owner's manual. I attached the link below. If down the road you feel expert diagnosis and repair is needed, you can visit SearsHomeServices to schedule a technician.

Your current details appear to indicate that the diagnostic test (blinking lights) on the optics board indicate that they are okay. I provided additional details on the procedure for jumping the T and H contacts on this ice maker module in the image below. Use 14 gauge


wire as shown below to jump the T and H terminals. The bare portion of the wire needs to be long enough to connect to the contacts in the ice maker module. If the ice maker module will not cycle with these contacts jumped then you will likely need to replace the ice maker module. If the module cycles with these contacts jumped as shown below but will not cycle on its own, then you will also need to replace the ice maker module since the thermostat in the ice maker module is likely bad.

NOTE: This information is intended for technicians. Use extreme caution when performing the procedures described below (and in the previous answer). Follow electrical safety guidelines.

Unplug the refrigerator

when accessing internal components. Do not make contact with the bare portion of the jumper wire when the refrigerator is plugged in.

If you need more help, submit additional details and we will try to assist you further.

NOTE: This ice maker system is not that easy to diagnose. If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
