I don't know if this is plausible, but---Is the thermistor losing its ground over that week where the light bulb snaps in? The light has the same ground at the other end of the light bulb holder. Maybe the light comes on and kickstarts that ground.
It appears to be something very close to what you are describing, but I cannot figure out what to do about it.
There are 4 wires. 2 for the Light assbly. 2 just for the Thermister. Both are separate from each other. Are you positive the Thermister is installed correctly on the Fin? Are your cooling fans operating? The White and Black wire bundle for the light and rear fans can be swapped by mistake on the rear control board. This will cause no obvious problems except the rear fans will not come on. Maybe it also causes your Thermister problem? The large white/small white goes on the LEFT terminal facing the control board. Doug
Both fans in the rear are coming on.
Thermistor is on the correct fin, and in the correct position.
Thermistor was the first thing I replaced when this odd situation starting happening.
Watching the thermistor temperature (in diagnostic mode (3)) the temperature will show oddly low readings (00, 11, 15) and upon opening the door(light comes on) thermistor will read 15, 18, and then if I push the door switch(plastic white door switch) causing the light to go off (no change), but then release the door switch(causing light to come ON) the thermistor will jump to the correct reading (usually in the 40's) and the cooling unit will come on. All is well for a few days, and then it happens all over again.
