Defrost Thermostat - With Wire and Clip

First I thank parts select for such fast shipment and correct parts.
The main problem was defrosting the coils between the freezer and fridge. The cover plate over the coils could not be removed untill some of the Ice melted.Removed freezer door, and screws each side of outer frige cover to enable cover plate to slide out.(Outer walls have to be pried out a little). R&R heater coil (shorted out and glass broken).Defrost thermo.located behind coils replaced as precaution. Defrost Timer located at bottom of fridge frame next to compressor. A couple of screws and unplug and plug in new part .(Also replaced as precaution-not qualified to test and dont want to do the job over) Thanks to google for info.First time for this job. You can do it.

The defrost timer was mounted in refridgerator by the temp. control. Just two mounting screws to remove. Tested this part as discribed in trouble shooting section. It needed to be replaced. Also found the defrost elements behind the rear wall of freezer, they were the glass tube type one was clearly blown. The freezer coils were a solid block of ice. No way the air could flow into refridgerator part. used a hair dryer to defrost also used a thicker wire ot unclog the drian that leads to pan under fridge. this one had two glass tube heaters that wear held in with two screws each. just unplug wires. I also replaced the thermostat since it was right there and it was the only other part listed that could cause the freeze up. bottom line its like i have a brand new side by side fridge. These kind are like $1500 to replace. So for $99 in parts and and hour or work I got my fridge back. Thanks for your help and getting the right parts here in just a couple of days.
