Mike, With this issue if the water continues to run for more than just a couple of seconds then this would most likely be either the water valve or the dispenser module is faulty.

John, You will want to make sure that the evaporator coils in the freezer compartment are not impacted with ice. If this is the case then test the defrost thermostat and defrost heater to make sure that they have continuity. If this checks ok then the main board would be the issue. Also check to make sure that the evaporator fan is operating.

Eric for Model Number Frigidaire FGHD2368TF3

is the thermistor located in the air damper assembly? also, does it come with the assembly if you order the whole assembly? my refrigerator is still freezing food, I have raised the temper by over 7 degrees Fahrenheit and I'm still getting frozen food. I have had the main control board at the bottom of the fridge and the touch screen panel that controls the temperature and I have also had the air damper assembly replaced but I'm still getting the same issue. I am now thinking the thermistor or something of that nature might be messed up.

1 Answer

Eric, Part # 5303918775 is your thermistor and this part reads the temp in the fresh food compartment and sends that info to the control. And this part can be in or close to the damper or under a white cover on right side of the refrigerator.

Eileen, take a look on the side walls of the refrigerator, there should be a small plastic cover, underneath the cover is where the thermistor will be located.
