I’ve had a job numerous times And they keep referring them to Warrantee because I’m assuming if the fuel system issue but I followed up with several of these customers and they said warranty he came out and fixed it in like 10-15 minutes. I have the job again and I’m wondering what the guys from warranty did there must be a service bulletin out for this basically build up a snow blocks only underneath where the fan is located on the evaporator you guys answer this question before that it might be deprived evaporator But how could they be fixed in 10 to 15 minutes? Please don’t link videos or diagnostic stuff unless it addresses this exact issue with this freezer fan.

Hi. I have found and attched a service pointer with pictures. This model has a 100% ff evaparator failure. Your serial number is with in the range as well. Double check the model and serial in the service pointer I attached. Please let me know if the link i have attached does not ooen for you. This is not a typical sealed system frost pattern as you will see in the picture. You would need to replace the fresh food evaporator and possibly compressor as well.

  • IT IS COOLING FINE BUT THE FAN IS HITTING THE ICE.
  • I have worked on MANY of these units. I have seen and repaired many of these failed evaporators. Even with good temperatures you could be getting early symptoms of a leak with this ice build up. Did you take a look the service pointer and the picture of the ice? IS this what yours looks like?? DO you have an even frost pattern across rest of the evaporator or no frost? Is a portion of the evaporator not frosted or dripping water? These would be signs of a leak. The leak is a small and slow one. Temps will slowly decrease. Ice cream will get soft first and then ice will stop producing. Did you check actual temperaturesin the units? I have seen similar units also build up a block of ice under the fan for no reason. The different run times of the unit along with warm air entering or humidity can cause this build up. Usage patterns and other environmental factors can play a part as well. I would thaw it out and most of the time it would not come back and if it did it would be 6 months later. There is not a fix for this. What i have done, and advise you to do as well, is change the defrost setting in diagnostics. Test 7 in the diagnostic mode will allow you to change the defrost setting from Adaptive to a normal 8 hr defrost. Also, there is a gold evaporator defrost sensor on the fresh food evaporator on most of these units. There has been an update to change the location of this sensor. Make sure the sensor is on the straight part of the suction (larger tube) line, near the joint. Make sure the sensor sits flat and that it is secured by a zip tie or by making sure the clip is tight. There is a bulletin on this that I am not able to find at this time. If the sensor looks corroded I would replace it. I would advised to just have a new one and replace it regardless when you disassemble the evaporator cover to update the location of this sensor.
  • Thank you!

Hello
See the service bulletin link below that could possibly be your issue. Normally when you have A no cool unit and ball of ice on the evaporator its A sealed system leak. We verify its A low refrigerant charge and then replace the evaporator and dye dryer. Matt Ace technician

  • Can you guys dig a little deeper? This website is my last resort but basically the Ifly only form directly under the evaporator fan not where the capillary enter the evaporator which would indicate there is a refrigerant leak. I have thrown away over seven of these calls since you guys suggested it might be a deprived system about eight months ago when I has to question before but several customers have told me that warranty came out and fixed it in under 20 minutes so I doubt it’s a sealed system issue.
