ZISS480DPESS General Electric Refrigerator - Instructions

After replacing the Defrost Thermostat, Defrost Heater Assembly, and the Main Board, I concluded that the problem must be the Defrost Thermistor, which I replaced in less than 10 minutes and it fixed the problem! I cut the wires on the old thermistor and connected the new one after stripping the wires and taped the new connections with e ... Read more lectrical wire.

had to rewire the harness in place in freezer. should have removed door for more room to work . easy job if you have 4 foot arms and a 1 foot chest.

Had to remove all the covers and fans to expose the condenser, which was difficult as the parts were frozen to it. The styrofoam covering the condenser made it almost impossible to defrost it. Therefore, I ripped the styrofoam off to expose the condenser. Was not really difficult to fix the styrofoam cover using metal tape. Replaced t ...

Lots of parts to keep track of, but anyone could do it.

Followed the video instructions with the help of a young man who worked on trailer hitches before and knew how to splice wires. Beware of splicing the wrong fan motor back into the assembly. . . . That happened here and we had to start the splicing all over again with the correct fan motor.

I followed the video provided by PartSelect, very helpful. I had to cut and splice 4 wires. The repair was successful. The replacement part was an exact duplicate of the original. I still notice the same sound but one tenth the volume. I hope the problem does not return. Many thanks to PartSelect for information to identify the problem an ...

Very limited working space in this model. Must remove grill and disconnect elect connector on motor. One additiional tool suggested: Extendable rod with magnet on end because you will most likely drop something. First, remove two screws holding motor to metal strap. Tool must be inserted between blades of fan in order to get to the s ... Read more crews and this is the hard part. Fan and motor are removed as one assy and this takes some manuvering. Might have to remove front screw on metal strap to gain more room. I did not attempt to remove fan shroud. My fan was attached to the motor shaft with a metal clip. Spray a good lubricant such as PB Blaster on the shaft, wait a few minutes and press it or tap it out gently. Save misc parts on old motor for reassembly. Your set up may be different so check out everything before starting.

I ordered 3 temperature Sensors Part#PS304103 and viewed the video. Got there, opened the frig. and it looked totally different and no place in any part of this frig. that took these sensors as viewed on the video. Totally baffled why these parts were listed for this frig. there was no place in this frig that would access for these part ... Read more s. Serial # was HR443071.Maybe this model is out of date for these parts. Trying to find someone who can repair it. Any ideas???Purchased this GE in 2008. Model #is GSS25WSTFSS Thanks, for your help. JIM
