Question about Kenmore 73502 / 73504 / 73509 Bottom Freezer Refrigerator
There have been a few posts on this problem. I'm having the same problem where the fresh food is warm, but the freezer is fine. I removed the rear wall in the freezer and there's ice buildup all around the coils and the hearting unit, which makes me believe the defrost heater is bad. Maybe the timer or a combination of both?? Can I check the heater tube for continuity and expect resistance if it's bad? Any other ways to check these to components? Any ideas would be helpful.
Hello , I can help. You can ohm the heater out to ensure its ok it should read very low res. less than 20 probably , you would be lucky to have a defrost timer in this unit most of these now have electronic defrost control boards that fail often , to find out which one you have take the control cover in the upper/fresh food settings area at top off and there should be a 3" by 4" small control board or a def. timer that's white or black with a harness connected to it that has 4 wires.
If you have a def. timer there is a dial you can turn until it clicks once and set it to defrost to test the cycle , if the defrost is working at this point this means the timer has quit and is not timing any longer you will need to replace the defrost timer.
If you have a control board this is most commonly the problem , replace the defrost board and you should be good to go. If you have any problems let me know , good luck. Phil
