Thank you for yur prompt response.
To answer your question, I do not see frost at the back panel inside the freezer. The refrigerator is humming but I do not hear the "fan " noise that I am used to.
Here is when I noticed things gone wrong: no water from dispenser in the morning and freezer top food is thawing.
Here is what I did after that. I took out all the half-frozen food in the freezer. I cleaned all dirt ( a lot ) from the bottom of the refrigerator. And I put 2 bottle of waters in freezer last night as I noticed the refrigerator is not totally dead. This morning, top one is a little cold and bottom one is frozed. There must be a circulation problem and/or ?.
Appreciate your quick response.
How do you know it's not thermostat ?
Should I check thermostat first before changing the fan assembly ? Any suggestion to check it ?
This is a side by side, Amana SSD22NW. Both side of the freezer and refrigerator sections have warm top and cold bottom. I did find little ice build up at lower in freezer. No freezer fan noise. I assume this is evap fan not working. ( The back of the refrigerator is working fine with fan running.) But it does not mean it's bad.
I ran through some web articles, they all suggest thermostat the most. Should I check thermo first ? And how ?
Sorry about your ear infection. Hope you get better.
panel done ! volt meter ready.
The fan stoped for a while and the compressor stops. The evaporator bottom tube is now running hot and steaming. I do not get 110 Volt at the motor at this time ; I think it is because the refrigerator is running 'defrost ' cycle ? How long do I have to wait to double check again ?
Yes. I think the main reason is that the thermostat is frozen due to too much moisture coming from the opening of freezer door. I have found recently sometimes the freezer door not fully closed. Is this a good theory to explain ?
Thank you. God bless you.
