PIC 1 – Typical Whirlpool Side x Side Freezer Panel
There was a patch of frost on the upper right, indicating a fan problem, not a defrost problem.
PIC 2 – Behind the panel
Note the frost in strange places up high. Sure sign of evap fan not running at some point. This fan was not running when I arrived, but fired up when I started removing the back panel. On these models, if the compressor is running, the evap fan should be running, no exceptions.
PIC 3 – After replacing the evap fan, I check for positive airflow here
There was no airflow. Why?
PIC 4 -Because the block of ice inside of here
Clearing the ice here is mission critical. Not doing so will result in a callback and the knowledge that “you done didn’t do your job”.
