Once I verified the fan was working, I put all the covers back on. I will have to remove the rear cover and see if the coils are as you describe.
The frost 'chunk' is no longer on the cover as the evap fan is now working. It blows cold air, just seemingly not enough.
This is after running for several days attempting to make temp on the freezer side....
new evap fan is running just fine blowing air, so the frost was not expected.
I also tried the following found here:
I measured the resistance of the heater at the control board as described above and had 21 ohms.
I also tested each thermistor at the J1 connector and had 13-15kohms on all 4.
John that is a coolant leak. When you see a pattern like that the reason the frost pattern does not go throughout the entire coilset is because there is not enough coolant to frost the entire coilset.That means you will have to call for a coolant leak repair and the following questions are the ones that you should ask before accepting an agreement for an appliance repair.Do you have a license to recover freon? (They must be licensed its federal law) That way they just cannot come out without you knowing and charge you then leave because they do not have one.What is the minimum you charge for a sealed system leak repair?Please and lastly ask them to bring the tools needed to repair a leak. They may find the part of your unit that is leaking and be able to repair it that day, that could save a second trip charge. What some will do is tell you they have to bring the tools showing up without them and then charge twice for coming to your home twice, you want to try and avoid that.This will give you some idea if you want to repair it or not.If you have questions about my answer please click the "Reply To Link" arrowed in the picture below. I will be happy to explain anything that is not clear. Also if you decide to give me a rating and have a problem doing that please let me know.Thanks,Barry
