Hi and greetings from Australia. I have an upright freezer Model No FN 1827 Sedt/cs Nr. 51/ 710030914. It has suffered a mischief from rodent attack on the wiring. This has caused numerous errors and alarming. I have cleaned it up and repaired the wiring. Now it runs ok with no alarm initially but times out with an alarm. I believe that it is not seeing the temperature and alarms accordingly. It does get nice and cold so I suspect that the temp sensor is faulty. Sound fair ? If so is this the sensor for it ? SKU: 9590084. Thanks for your time
