It's like it is stuck in defrost but all food still frozen

Check the user manual , Could be a gas leak, thermostat may be stuck or frozen, cooling fan may have stopped working, may need defrosting if not automatic.

Sounds like your refrigerator is getting stuck in the defrost cycle. Not knowing your model #, You can have a Timer or a Defrost control Board defective.

I would check your defrost timer to see if it is rotating. It may be stuck in defrost mode. you can check this by manually rotating the timer dial CCW yourself. This will be located in the front bottom left had corner behind the vent panel.

manually rotate your defrost timer maybe it stuck up and the contact was on the defrost heater. adjust your thermostat setting to coldness then observe unit.

Yes, that would be okay. I do that all the time with my meat.

Frozen food should be defrosted before cooking in halogen ovens.

Halogen ovens use only radiant heat and will not cook the centre of frozen food.

Either the fan that blows cold air from the freezer compartment to the fresh food compartment is burned out or the door/flap that seperates the compartments is stuck or the linkage connecting it to the fresh food temperature dial is stuck or broken.

The evaporator coils are in the freezer compartment and air is blown from the freezer compartment to cool the fresh food compartment. For some reason, air is not moving to fresh food compartment.

If the fan is running, it could be something as simple as Ice blocking to door between the freezer and fresh food compartment. I know modern refrigerators are self-defrosting, but that's only the evaporator coils, which are defrosted by a timer and a heater.

Ice can form on passageways inside the refrigerator, like the exit of the ice maker and in this case, on the door and 'tunnel' between the freezer and fresh food compartment. It's free, and doesn't take a lot of time, so try completely defrosting the unit before doing anything else.

BE SURE to keep the doors open, as odors can form as particles of food are allowed to defrost that may have been frozen in an ice pack for months or even years. Clean the interior of the refrigerator while you have everything out and reset the controls to normal settings.

If this doesn't help, there may be a mechanical problem with the air transfer control flap/door that will need to be fixed.

Hope this helps.

Ice on the back wall indicates a problem with the defrost cycle. The ice builds up and starts to choke off the air flow, so your symptoms would indicate that may be happening.

Defrost problems are usually any of the three components, the heater element, the defrost termination temp switch, or the defrost timer.

one of the hardest things to diagnous is food defrosting in the freezer. i found out the hard way about 35 years ago, but not until i banged my head against the wall a few times. the problem was the customer didn't have enough food in the freezer as she was a weekender.frozen food needs frozen food to keep the food frozen confused? so was i . every time your refrigerator goes into defrost( usually every 8 hours) a heating coil comes on in the back of the freezer. if the freezer is not full enough this heater can raise the temperature in the freezer to 40 degrees which will soften the food and melt the ice considering the time it takesto refreeze the food. i never forgot that service in fact i can see it in my head right now.. try this cure first let me know

If this is not a frost free model It sounds like you have a freon leak. This is almost never worth fixing. Any fix would be temporary. You can never really trust it again.

If it is a frost free model it could be just stuck in defrost. Most commonly the defrost timer.
