Older Amana fridge

[Mr. screw up]

Hi Guys.....  Great information thank you..

I have an older amana fridge it is an Amana 20 frost free and a serial number of BO20W-AG it claims on the tag to draw 6 amps and says it takes 8 oz of R-12 refigerant...

It is one that has the freezer on the bottom and I really love it but recently the temp started to rise in the box to where stuff in the freezer was mush so I read that a likely problem was that the evaporator coils in the freezer could clog up with ice which when I looked into the inside of the freezer box I could see that the back wall was completely frozen....

So I removed the contents of the freezer and placed a hair dryer near the coils and I unthawed a lot of ice which was also evident by the evaporator water pan bieng 1/2 full so I then also cleaned the steel coils undernath (covered in dust) by blowing compressed air and it seemed to hum along again...

But now I see that slowly over a week the temp is agin rising, I know there is one fan working because I can feel the heat bieng pushed out at the bottom.. where would the evaporator fan be located to see if it is operating as I am feeling that it's either the fan or a thermostat....

Also kind of funny when the machine was running really well when it finsihed it's cycle it would make a kind of klunk sound as it ended which now I do not hear...

Thanks again for any help that you can give this homeowner....

Your heater or termination thermostat is probably gone out. She's defrosting as always but just no heat is being applied and after a week or more the temp begins to rise. You should check the heater it is probably shot and replace the termination thermostat regardless because of it's age.
