yes there does seem to be. Is that good or bad?

[bigbuck]

if you have frost on the back wall, then you have a defrost problem , 3 possible problems , defrost heater, thermistor or thermostat, or control. if you have a ohm meter , you can check heater & thermistor. 1st. best to defrost the evap. coil with hair dryer or steamer.

The other day I worked on a GE ice box that had ice buildup because of defrost failure. I made a video:

I'm going to defrost it with a hair dryer now. Let you know what I find.

[KevinC]

The defrost heater is good and I think the thermostats are ok so I ordered a new control board.

Do you guys see many problems like this with bad control boards?

[bigbuck]

I would change thermistor too!!!
