When I openned the freezer this morning everthing was defrosted.
Here's what I've got;
Checked the temp's and refrig was 50° and freezer was at 40°
I cleaned a little dust off the condenser but not enough to block air flow. The compressor was warm/hot and it's fan was running.
I opened the back wall of the freezer and there was no ice on the coils and it's fan was running.
I located the tech sheets behind the kick panel and ran it thru the diagnostic tests and they all checked out.

Defrost thermostat and defrost circuit tested open.
Fresh food thermistor passed .
Freezer thermistor passed.
both fans work.
and the damper to the frig opened and closed.

I'm guessing it's the control board or it needs a freon charge, But I'm not an appliance guy and could use the advice of some pro's

Thanks in advance
Dan
