Rf26j7500sr/aa only hslf defrosting
« on: September 10, 2021, 11:03:53 AM »

This fridge, the fresh food compartment only defrost bottom half of evaporator, so ice built up in the upper part of evaporator. The fan blade is hitting the ice. How can I make the defrost complete? That means how can I extend the defrost so no more frost is left st the end of the defrost cycle? Please help! I am showing the picture of the pattern that I saw when the cover plate was removed. These pictures were from two different times a few days apart. I cleared the frost every time I went to the customer's home .

How did you defrost it, with a heat gun or using forced defrost mode?
Did you test the defrost heater and prove it works, correct current/resistance?
Did you defrost both evaporators?
Are the drains for both evaps clear?
Do the doors close and seal completely by themselves, meaning they can't be left partially open?
Are there containers of liquid/water/soup uncovered in the fridge?
Is the icemaker dripping any water into the fridge?
Is there any water under the cool select drawer or crisper?
Are there any error codes?
I seem to recall a tech bulletin regarding some models about moving the thermistor on the evap to achieve a better defrost.
