Hi Dave and welcome to FixYa
, I am Kelly,
Take a look in the back of the freezer compartment. Look for any signs of icing on the back access cover. Usually but not always the evaporator coils freeze up because the unit is not automatically
defrosting properly or there is a problem with the evaporator fan not running fast enough / at all. Press gently with your hand of the back cover of the freezer compartment and feel for ice. Also check the front of the chassis for signs of being HOT. It is ok to be warm not hot.
Also check to see that the light goes on and off as you actuate the light switch plunger. Some units have the door switch in the top of the door hinge but most have the switch in the door fold area of the chassis some where.
If you find that the evaporator coils have iced up:
- Perform a manual defrost of the unit but first unplugging it
- Remove the freezer contents
- Direct an external fan into the freezer compartment for just over 2 hrs. (makes a water mess)
- After 2 hrs clean up the water mess and return the unit to normal service.
- Watch after 3 days if the fresh food compartment once again starts warming up. If it does you have and automatic defrosting problem.
No ice noted:
- Possible temp control problem (Thermostat / cold control or thermistor)
- Possible Air Damper problem. There are 2 kinds of air dampers. One is electrically controlled and the other is nothing but a mechanical baffle that is positioned partially open. If you have the electrical type the air damper motor may have failed or the movable baffle is stuck.
Front of chassis is almost HOT to the touch vs warm:
- Open the back of the unit by removing the black fiberboard cover and inspect for lint and that the condenser fan is running anytime the compressor is running.
Light always on:
- Door switch failure. Some door switches also control the evaporator fan along with water in door and ice in door functions. The water and ice in door should NOT work with the door open.
The above is pretty much an in home repair techicians check list for the symptom you describe.
If you discover that you have an automatic defrosting problem I will need you MAKE & MODEL number via your next response here so I can tell you what you can do to troubleshoot. (
