A thermistor is an electronic thermal control(Thermostat)So, yes it could cause a defrost. Use a multimeter on the resistance settings and check for a short through the thermistor.(the most likely cause) But, short or open circuit would mean you need to change it.

no the defrost thermostat only need be checked at cold temp and at room or reg temp it should not show any continuity have u checks ur heating element out as well and defrost timer ? I still suspect a faulty thermistor the freezer has more than one thermistor?

Fridge side is not cold and freezer side ice building up on the back panel fan is working is it the thermistor causing that and how many ohm's thermistor should have

Defrost heater is open and needs to be replaced. Or maybe the defrost timer is no good along with defrost thermostat.

Check them out.

Ice build up in Freezer on left side

Sounds like a defrost issue. this could be a bad defrost control, defrost heater or defrost thermostat. There may be a defrost thermistor that control the defrost control. You will have to research what your refrigerator has to see what could be causing the ice build up. I would start with the defrost control then the defrost thermostat. If your refrigerator has an electronic control then check to see if the thermistor is bad.

Defrost timer

The defrost timer is part of the electronic control baord located on the back of the refrigerator. If the freezer is not defrosting check the thermistor on the evaporator(freezer) coils. It can cause the control board to thing it doesn'y need defrosting. a common problem

Freezer defrost too warm

thermistor develops a control signal, the heater current does not flow through it. Sounds like defrost heater stays on too long

GE Profile Side-by-Side running warm

If it's cutting off at too high a temperature it is a good possibility the probe is faulty. However if the compressor is not cutting off at all, suspect short of gas.

The compressor and fan won't come on but there is power supply working for the lights

Without your MAKE & model number; all I can do is tell you what can cause this symptom.

At the end of the defrost cycle the defrost control is supposed to get a signal from either a 60 deg bi-metal thermostat or thermistor (depending upon make & model) That signal starts the clock either mechanical or electronic that signeals the compressor to start. The fan automatically will run when the compressor runs. If the defrost thermostat or thermistor is not working correctly the unit will start a defrost cycle but never finish so it completly defrosts.

The termperature control will also cause this symptom. If the corntacts in the temp control fail the compressor will not restart.

Just from reading your symtoms I think you have a problem with one of the following:
1. Defrost thermostat or thermistor
2. Defrost control
3. Temp control

Most of the time it is either 2 or 1 above in that order.

If you respond with a make and model number I will use that to determine if there is anything you can do at this time to troubleshoot.

All od the sudden my side by side ge artica keeps refridgeratoor at about 40 degrees and freezer at about 16 degrees

Open the freezer and look for frost buildup on the back panel. If you see frost, you have a defrost problem. Possible causes are the defrost heater or evaporator thermistor. You will need a multimeter to test the components. The heater should show continuity. The thermistor should be between 10k and 80k? at fridge to freezer temperatures. Anything less than that, the thermistor is bad. Remove the back panel of the freezer to access. The heater is mounted to the bottom of the evaporator coils. The evaporator thermistor is mounted to the top of the evaporator.

If no frost, I would suspect the freezer thermistor. It's at the left lower rear of the freezer or behind a grill on the right wall of the freezer. Same thing, if it reads less than 10k? replace it.

If all the components check good, the only thing left is the main control board. You can find this behind a panel on the back of the fridge.

Part numbers: Defrost heater WR51X10055, thermistor WR55X10025, Control board WR55X10942.

Freezer has thawed twice in the last 2 weeks

Hi and welcome to FixYa, I am Kelly. This can be caused by several things but usually when it thaws on a routine basis the automatic defrost bi metal thermostat has failed. Using this model number PSS26MSRCSS and this diagram:
The failed part would be item 240. It is possible however that the thermistor Item 241 could also cause this symtom.

Make sure to read the information about the Defrost thermostat using the link below. Just note that a defrost thermostat will have continuity anytime the temperature is below 60 deg F.

GE Thermistor testing can be found here:

These are the 2 most common reasons that the a refrigerator will thaw out on a regular basis. Now there can be things like a problem with the PTC relay or thermal overload on the compressor in the form of loose / hot terminals or a bad relay / overload assy. Lastly and repair of last resort the compressor can be dragging and not starting properly or the rotor occasionally locks.
I believe that if you change out the thermistor and bi-metal thermostat that your defrosting probelm will cease. We usually change them both at the same time because the control board is electronic and under nomal conditions the thermistor controls the defrost cycle. The Bi-metal thermostat is there as a back up to terminate the defrost cycle when the temp at the top of the evaporator reaches 60 Deg F and at that time cycles the compressor to start.

Having said all that... if the defrost heater Item 230 of the first link is not heating up at all; the unit will defrost / thaw to 60 deg F every defrost cycle. Most of them will have Blue and orange wires on them and you read resistance at each end of the glass tube on the terminals. No resistance = an open / failed element.

Frost buildup in the freezer?

If you have frost buildup in the freezer then the most likely cause would be an issue with your defrost system. Theres is a few possible causes the most common would be a bad defrost heater.

1)You can unplug the unit and remove the back panel of the freezer.
2)remove 2 screws holding in the defrost heater (located at the bottom of evap coils)
3) remove 2 wires on heater and ohm heater with meter if shows no continuity then heater is bad
4)according to GE you need to replace defrost heater and thermistor located on top of evap coils.
5)def heater number is wr51x10055 and thermistor is wr55x10025.
6) if heater is good check to see if termination (also on top of evaporator seems to be popped out or bowed)
7) if none of these are the case it would be an issue with your main control board and you may want to call a qualified tech
