First I turned off the refrigerator and allowed it to defrost. I had to use a blow dryer to save time since it iced up so bad. Removed all the racks, ice maker, and back panel in the freezer. Found the Bimetal Defrost Thermostat, cut it loose from wiring harness and attached new one by matching the wires and reconnecting with two butt connectors. I then ran the hot blow dryer on the drain in the rear until the ice melted and it was open again since it was frozen up causing the water in the bottom of the refrigerator. Reassembled freezer compartment. Then I replaced the Defrost timer by removing two screws, lowering the refridgerator control box. Removed old timer and installed the new one. I broke both studs used to hold it tight trying to pry them off but there was enough left to drop the timer in place without fasteners, you can not easily use the screws provided due to the location of the timer. Reconnected the wires as shown in the installion instruction and the wiring schematic found in the control box. Reassembled the control box and plugged in refrigerator. Waited about 15 minutes for it to recycle and problem was solved. Inially I thought something was wrong because it did not come on instantly but after 15-20 minutes it cut on and got cold. I replaced both components that typically cause the problem but you can determine exactly which one or both using an ohm meter. I did the entire job myself for just parts which is less than $75.00 for a service call. Thanks, you folks are the greatest.
