Need to replace fridge freezer thermostat

[Yan]

Hello guys, my freezer dont defrost. I need to use an hairdryer to melt the ice/snow when thing start to come soft. I've done the autodiagnostic and its read " O" for the defrost thermostat. I've looked for the part to change, but the only part available OEM ( part # WPW10292244 ) is a complete harness with the t-stat and other connector for a hefty  price. So it's why I'm here to ask for a replacement t-stat. It dont bother me if I need to cut wires and do some soldering. I just want to avoid to replace a complete harness and pay too much for it. Here the informations:

Refrigerator :Inglis ITB19440Q02

T-Stat ident ( whats written on the T-Stat)

FPS 39TVER31    40056

L42--30F    S15912E

126393-24

 I have a pic of the thermostat, but I dont know how to attach it to the message here. If you can help me with a compatible replacement t-stat that will work with my fridge it would be greatly appreciated.
