The model is RS21DCNS, seriel no. 854042BLCo1926B.
I took some measurements.
Freezer drain heater measures 1.2Ohms, I read the fridge side one should read 2.11 OHms, anyone any idea what a new or fully functional FREEZER side drain heater resistance should read ?
I checked the thermal fuse, that is ok.
The main evaporator assembly heater in the FREEZER side measures 230 OHMs, again I know the fridge side evaporator heater should measure about 485 OHms to pass the test, does anyone know what resistance the FREEZER side evaporator heater should read ?
I checked the defrost sensor, that is responding ok, i.e. it's resistance changes when I warm it to 20C and resistance increases when I cool it to about 0C in an ice/water mix.
Fan is ok.
ANY advice on what reading's I should get on these two FREEZER side heaters would be very helpful. Thanks Adam
