Cleaned the condenser its super clean. Replaced the condenser fan last year. I have no idea if the fan inside the freezer is turning on. Was also thinking maybe the wife over packed the freezer with bags and chocked out the airflow. Fridge is 22yrs old but replacement is not an option. Do you think I should lower the pressure to closer to 1-2 or so.Cut out for that unit is 1" vacuum. Can you see light thru the condenser, lots of dust in your pic.
Although I vacuumed the condenser with the flashlight I can see there is still a lot of dust. I cleaned it with a qtip last year. So I’m going to grab a few cans of compressed air. Also confirmed the fan is working in the freezer.Adding & removing freon is guesswork. To be sure you would have to evacuate, change dryer & recharge. The evap fan is behind the evap which is behind the ice maker. Two switch's up top, left lites, right fan. Again can you see lite thru the condenser(flashlite)
Already checked the drain it’s clear. The ice falls off puddles on top and makes its way down under the fridge.In all the years I've serviced Sub Zero I have never seen frost back forming enough water to make it down to the floor. In your case I would check the drain trough in the ref section to see if it's over flowing. Not gonna solve the frost back issue but might be the cause of water on the floor. After 22 years that is remarkably clear
I lowered the pressure to 1.5psi and raised the temp from -3 to 0. It still frosts but not enough to melt and puddle. Seems like a Bandaid for nowIn all the years I've serviced Sub Zero I have never seen frost back forming enough water to make it down to the floor.

With a guage hooked up to the freezer I never see the pressure move. It just sits at 1.5. What is the on and off for the fridge? Because the pressure measures 30psi and isn’t moving. Last question. Do you recommend anyone for repair in the Hudson Valley Ulster County NY?In all the years I've serviced Sub Zero I have never seen frost back forming enough water to make it down to the floor.
