General Electric chest freezer temp alarm keeps going off even though unit is running at -15. Changed electronic control and unit still sounds the alarm. Tried to remove thermistor from well but it wouldn't pull out. I was afraid to pull so hard that I would break the old one and really be screwed. Should I just pull harder? Any other thoughts?

Hi,

Tried to remove thermistor from well but it wouldn't pull out. I was afraid to pull so hard that I would break the old one and really be screwed. Should I just pull harder?

Best suggestion that I have is to open the lid and defrost the freezer for a minimum of 24 hours and then try to remove the sensor.

That's a good suggestion, thawing out the unit.

I also had a thought that perhaps the freon charge is low. The thermistor is in a well that's nearly at the bottom of the freezer, right next to the compressor. If the thermistor is sensing close to a cooling tube, then a low refrigerant charge could cause a "warm" spot, or at least the electronic control thinks its too warm, thus running all the time and running too cold. Unit is currently running at -15F.

Unlikely a low refrigerant charge would allow the freezer to get close to -15F.

JMO!
