Yes your refrigerator could and most likely has a thermostat problem. Thermostats go bad in several ways, by not sensing the correct temperature, not working at all or sticking on until fresh food section becomes a freezer. Although I cannot find a Frigidaire Model RIR1450 in the US database that does not mean there is not one worldwide. Your refrigerator does have a thermostat most likely behind the control panel inside the fresh food section, Thanks Sea Breeze

SOURCE: Fridge not working

Speed, If your model number begins with 596. This is made by Amana with the Kenmore name. Look at your defrost thermostat that sits on the evaporator, see if its bulged. If it is it's more than likley your problem. Part number 12001937. Your heaters should be calrod and seldom fail. Advance the refer into defrost by turing the mechanical timer clockwise until you hear it click and see if the heater comes on. Should find the timer under the control panel, should be a slot you can use a screw driver to turn it. If the heaters don't come on you can temp. by pass the bi-metal by simply cutting it out,connecting the wires and putting it into defrost again. However, it must be replaced. This is a safety device. If the heater now comes on, it's your bi-metal. If they don't come on with the bi-metal by passed, check for 120V at the heater connection. If no voltage, its your defrost timer. Careful in there your working with live voltage...Catriver post back.

SOURCE: Defrost timer

The above URL will take you to an exploded view of the controls. Look at number 23 which will be located behind toe plate below door on the left side. That is the defrost timer. Rotate the clutch head screw Clockwise SLOWLY until you hear a loud click. That is the defrost timer starting the defrost. If the unit restarts after 18-22 minutes and defrost does not take place you problem is most likely the defrost thermostat.

SOURCE: Candy CPCA250 GB Freezer feezing but fridge not cold

Hello jonnyclewlow

You said, you recently had a problem with my Candy fridge freezer (it defrosted overnight and wasnt cooling at all) and a repair shop diagnosed a thermostat problem. I have replaced the thermostat, Now the freezer freezes without any problems but the fridge does not go cold at all.
Also the compressor is running constantly

This is my first thought

Fresh Food temperature is
too warm. Freezer
temperature is satisfactory.

1. Fresh Food control is set too
2. Set fresh food control to a colder setting. Allow 24
hours for temperature to stabilize.

3.Then see if you do not have your freezer articles packed full up to the top, or covering the cold air vents usually found in the rear of the freezer compartment.

The fridge and the freezer share the cold air so the air must not be restricted from travel form the freezer to the fridge and back!
This would also cause the compressor to run none stop trying to cool the fridge!
So check your air vents in the freezer.
I'll bet you did not know they were there !
Most of us never notice!
Hope this works for you.
Please let me know that one of these solutions worked for you!
or if you have any questions.
Thank You, huuum

SOURCE: Freezer coils freezing, fridge warm

You might want to check and make sure the interior fan is working above the evaporator coils. If the fan isn't working the air won't circulate over the evaporator and it will frost over very quickly, and also cold air won't be pushed into the fridge side.

The fan might turn off when the door is open, hold the door switch shut while you check it.

Kenmore fridge, 59665932403, Froze up.

Could be an ice buildup behind the fan, in the air passageways or around the fridge thermostat.
Could also be that the DEFROST thermostat needs to be replaced.

The fridge part is too cold causing the food to freeze and the temperature knob not working... out of warranty

sounds like a defrost timer or defrost thermostat issue u can check with a multimeter, the timer can be checked with a sml flat head screw driver inserted in the tiny slot at center and turn slowly till u hear it click once not twice, u will then turn on the defrost timer. this will give another 10 -15 days before it will be all froze up agin. if the defrost timer does not come on after trying this then u may have a bad defrost thermostat, of course u also want to check the cold control knob and the cold control vents are working properly

Frigidaire side by side model # FRS20ZRGW3 coils freeze up on freezer side, fridge side gets warm

You have a defrost timer behind the front kick plate turn it clockwise slowly until compressor and fans stop. Once this happens the timer should remain off for 30 minutes and the defrost heater should come on during the first 15 minutes. If after 30 minutes the defrost timer part=> 215846602 Defrost Timer Assembly should come out of defrost and the compressor and fans should restart, if not advance the timer clockwise until they start and replace timer. Try that first and tell me what your results are. If that is not the problem then we can narrow this down to the defrost heater=> 218657301 Defrost Heater or 5303917954 Defrost Thermostat How to test the defrost heater is found on same page as the defrost heater. If you have any questions I will be here to help you, Thanks Sea Breeze

Hi Rob,

The problem in your case is most probably with the defrost thermostat.

It can be found on the evaporator i.e. freezing coils , it's round disc like with two wires.

If you get this replaced with a new proper working unit ,

Also make sure you replace the defrost timer as well if the problem persists.
Hope this helps ..:)

  • Well I can say one of the components responsible for defrost has failed -defrost timer, defrost heater or the defrost thermostat.

  • Unplug the refrigerator and pull the back wall off of the freezer.
  • Now unplug the defrost and the thermostat.
  • Get your Ohm meter out and test for continuity across the heater and the thermostat.
  • No continuity on the thermostat means that needs replaced and the same for the heater.
  • If both of them parts test out OK then you need to replace the Defrost Timer.

  • One of them is bad guaranteed. You want to make sure that there is some fresh ice build up too after cleaning it all off. This insures that which ever component that might be bad is verified messing up again per the ice. Then do the testing.

Fridge stops working and warms up for half a day then will cool back off and start working for a day or a few days. When it warms up everything in the freezer defrosts but will then refreeze a day later...

Check your defrost thermostat in your freezer access panel. Your defrost timer could be faulty, Your defrost timers ussually run for 12 hours and defrost runs for 30 minutes. That being said that is why I believe your timer is getting stuck on run and then eventually it finally gets unstuck and goes into defrost. Eventually it will get stuck in one place or another.

If the defrost heating element, defrost timer or evaporater fan weren't working, you'd develop a block of ice on the evaporator. Is the compressor running? If it is, it might have bad valves from the frost buildup scenario. Liquid refrigerant could have gotten to the suction valves. The sealed system should have a five year warranty.

Kelvinator fridge/freezer problem

It could be a thermostat but is more likely to be a defrost problem. If it freezes up within a short space of time I would suggest contacting a fridge guy who should be able to diagnose either the defrost heater, defrost thermostat, defrost timer or thermostat. Hope this is of some help.
