Both GE and LG publish troubleshooting material for refrigerators, and LG’s refrigerator error-code guide adds fault codes for the freezer and refrigerator cooling systems. Neither GE nor LG publishes a page dedicated to a freezer that stops freezing while the refrigerator compartment still seems cold, so this guide sticks to the checks and codes those manufacturer documents actually describe.

Verification: Checked on 2026-10-05 against GE Appliances Refrigerator - Not Cooling Enough (contentId 21185), the GE Appliances refrigerators/freezers troubleshooting FAQ, and LG’s LG Refrigerator Error Code List. GE’s owner-level checks are quoted below; LG’s fault codes and its manual-defrost procedure are quoted below. Fan, defrost and sensor layouts and part numbers are model-specific — confirm them in your model’s manual.

Check the basics first (nothing to buy)

GE’s “Refrigerator - Not Cooling Enough” page says that if the refrigerator is running but not cooling at all or is not cold enough, there are several factors that may influence the temperature. Its owner-level checks, in GE’s own words:

  • Temperature controls. For dial or digital readout models, adjust the temperature control by one number higher for a cooler setting.
  • Time since installation. GE says newly installed refrigerators need about 24 hours to cool down and stabilize, and that if 24 hours have passed with the controls set properly but the unit is still warm, you may need to schedule service.
  • Food load. GE notes that closed containers of water, food or non-perishables help stabilize the temperature.
  • Door closure. GE says to check for large items such as trays, platters, food items (like pizza boxes) and ice behind the ice bin that may interfere with door closure, and to make sure the door gaskets are sealing properly.
  • Large containers blocking airflow. GE: large containers in back may block the flow of cold air and adversely affect the temperatures in the refrigerator; it says to move tall items forward.
  • Dirty condenser. GE says that when the condenser coils get dirty, the sealed system does not operate as efficiently as possible, and that if your model has coils to clean, the directions are in the owner’s manual. GE adds this safety notice with the condenser guidance: “To minimize the possibility of electric shock, unplug the appliance before attempting any maintenance or cleaning.”
  • Installation temperature. GE: the refrigerator may not cool properly if installed where temperatures are below 60°F or above 110°F.
  • Air clearance. GE: at least 1 inch of air clearance is required on each side, top and back of the refrigerator.
  • Interior lights. GE says to close the door slowly; the light should go out when the opening is reduced to about 1 inch, because a light that stays on produces heat that affects the temperature.
  • Diagnostic mode. GE: if the refrigerator was just serviced it could still be in diagnostic mode — disconnect power for 30 seconds to reset the control panel, after which it should cool normally.

GE’s refrigerators/freezers FAQ lists the same set of items to check when a refrigerator isn’t cooling properly: Temperature Control Settings, Time Since Installation, Refrigerator and Freezer Food Load, Refrigerator and Freezer Door Closure, Large Containers Blocking Airflow, Dirty Condenser, Temperature of Installation Area, Proper Air Clearance, Interior Lights and Diagnostic Mode.

Fault codes LG documents

LG’s refrigerator error-code list describes fault codes for the freezer and refrigerator cooling sections. LG documents an owner-level reset or defrost step for some codes; for others it states that the unit requires a professional inspection.

  • FF — Freezer Fan Motor Error. LG: this error indicates an issue with the freezer fan motor, and can also occur if ice buildup blocks the fan. LG’s documented step is to unplug the unit and leave the doors open for at least 8 hours to clear the ice buildup.
  • dH / FdH / dHF — Freezer Defrost Fault. LG: this error indicates a malfunction in the defrost system, likely caused by ice buildup, a blown thermal fuse, heater failure, or a main board (PCB) issue. LG says the code displays when the unit spends more than 1 hour trying to defrost and the evaporator does not reach its preset temperature; LG’s resolve step is to unplug the refrigerator for 2 minutes to reset it, and LG says that if the error persists the unit will require a repair service.
  • dS — Freezer Defrost Sensor Error. LG: this error indicates a malfunction with the freezer defrost sensor; LG states that it requires a professional inspection.
  • FS — Freezer Sensor Error. LG: this error indicates a malfunction with the freezer sensor; LG states that it requires a professional inspection.
  • rS — Refrigerator Sensor Error. LG: this error indicates a malfunction with the refrigerator sensor; LG states that it requires a professional inspection.
  • rF — Refrigerator Fan Motor Error. LG: this code indicates an abnormality in the refrigerator’s fan motor, which may be due to frost buildup. LG’s rF entry documents the fault and this possible cause but lists no owner-level fix, so a persistent rF fault should be scheduled for service.

LG’s manual-defrost procedure

LG’s error-code guide gives a manual-defrost procedure for frost-related faults: unplug the unit and remove all food and ice from the ice bin, leave the doors open and wait at least 8 HOURS for the refrigerator to defrost, and keep towels in and around the unit to soak up excess water after the frost melts. After 8 hours, use a dry towel to remove any moisture left inside the refrigerator and freezer, plug the unit back in and wait 24–48 hours for it to return to normal operation. Make sure the vents inside are not blocked, the unit is properly leveled, and the refrigerator and freezer doors are closed completely.

Door gasket and alignment

LG notes that for French Door units you should check the gasket along the side of the door to ensure it is not torn or damaged, and that frost buildup can occur if the doors are not aligned properly. LG says that if leveling the refrigerator and aligning the doors do not resolve the issue, the unit will require a repair service.

Model variation warning

Fan, defrost and sensor layouts, and part numbers, vary widely by brand, model and year. LG’s codes apply to LG refrigerators, and GE’s checks are specific to its own models. Confirm the layout, codes and any diagnostics in your model’s manual.

When to call a pro

  • GE: if its suggestions and tips do not fix the issue and the fridge is still not cooling or not cold enough, you may need to schedule service.
  • LG: the defrost sensor (dS), freezer sensor (FS) and refrigerator sensor (rS) codes require a professional inspection; LG documents an owner-level step for the freezer fan (FF) and defrost (dH) codes and says to schedule service if a dH fault persists; its refrigerator fan (rF) entry lists no owner-level step, so a persistent rF fault should be scheduled for service.
  • Do not work on sealed refrigerant systems or gas components.

Parts & tools (categories)

  • Freezer door gasket (model-specific)
  • Defrost heater / thermal fuse (model-specific)
  • Freezer fan motor (model-specific)
  • Defrost / temperature sensor (model-specific)
  • Manual-defrost supplies: towels

Search by your model number on the manufacturer’s parts page rather than by generic name.

FAQ

Q: Why is my freezer not freezing but the fridge is cold? A: GE’s not-cooling troubleshooting starts with the owner-level checks above (temperature settings, food load, door closure, blocked airflow, dirty condenser, installation conditions, interior lights and diagnostic mode). LG’s error-code guide adds cooling-fault codes such as a freezer fan motor error (FF), a defrost fault (dH) and sensor errors (dS/FS/rS). Neither GE nor LG publishes a page dedicated to this exact symptom.

Q: Can a freezer fault show up as a code? A: LG’s guide lists cooling-fault codes — FF (freezer fan motor), dH/FdH/dHF (defrost fault), dS (defrost sensor), FS (freezer sensor) and rS (refrigerator sensor). LG documents an owner-level step for FF and dH, and states that the dS, FS and rS sensor codes require a professional inspection.

Q: How do I manually defrost the refrigerator? A: LG’s procedure: unplug the unit and remove all food and ice from the ice bin, leave the doors open and wait at least 8 HOURS, keep towels around the unit to soak up water as the frost melts, then dry out any remaining moisture with a dry towel, plug the unit back in and wait 24–48 hours for normal operation.

Q: When should I call a service technician? A: GE says that if its checks do not fix the issue and the fridge is still not cold enough, you may need to schedule service. LG states that its defrost-sensor (dS), freezer-sensor (FS) and refrigerator-sensor (rS) codes require a professional inspection, and that a dH defrost fault still present after the documented reset should be scheduled for service.
