Randell model 2020f ice on evaporator - Randell Refrigerators

The evaporator will frost over if the fan is not working. Replace the fan
APPLIANCE 911

if it has a leak between the walls there is nothing you can do except put in some stop leak freon but that usually does not work very well

Well, no, actually. P2 is an error related to the evaporator temperature probe. I would start with the electrical connections, the bond between the probe and the evaporator, and the evaporator fan.

2 DOOR RANDELL. HOW TO REPLACE EVAPORATOR.

I'm sure it's the evaporator, I've got similar problem. The evaporator ice separator blades loosed.

Your system uses R-134a refrigerant.

If the compressor is running but it's not cooling, you probably have a refrigerant leak or possibly a restriction in your evaporator.

Unfortunately, refrigerant leaks are not DIY friendly, so my advise would be to call a competent repairman.

Check out the self defrost mechanism. If not working you will have a frozen over evaporator. The ice serves as insulator to keep temps on high side. Go to this site for part

During the cooling/freezing cycle condensation forms, this drips into a pan and then is evaporated by a heating element.
One of two things could be wrong.....
Your drip pan is clogged
or
your evaporator unit is bad

Hope this helps

I searched till I found a Randell vendor in our state. They had the answers I needed.

Yes. Unplug and add ice as necessary.
