I have a Subzero built-in freezer which is showing

Customer Question

Good morning. I have a Subzero built-in freezer which is showing "EC" and "Service". It showed the same thing a couple of weeks ago. At that time I took off the bottom plate and cleaned the screen which was pretty dirty and it started working fine again. It is now showing the same messages. I have checked the screen and it is clean. What should I do next?

Hello, I'm Joel and will be glad to help you today.

There should be some numbers flashing along with the EC can you tell me what they are, thanks.

ok thanks for that give me just a moment.

Expert:  Joel Swenson replied 1 year ago.

ok that means that the computer is saying that the compressor has ran too long, what is the temperature of the freezer?

Customer: replied 1 year ago.
It started at 6 and climbed quickly to 9 with the door open

Ok so watch the temperatures in the freezer for the next day or so, there are several things that could be going on to make the compressor run too long.

1. The thermostat is bad and its getting colder than it should and its not cycling on and off properly in which case the unit will get super cold and you will notice.

2. The defrost system is not operating and there is ice building up on the evaporator not allowing the fan to properly circulate the air throughout the unit. In which case you will notice the temps begin to increase over time and also ice buildup on the back wall of the unit.

3. The fan in freezer is not running to circulate air in the unit. You will notice a temperature increase and also you would most likely notice the fan is not running inside the unit.

4. The sealed system has developed a freon leak, in which case you will notice a gradual temperature increase in a short amount of time until at some point it no longer cools at all.

So short of having a tech come out and pin point it now, you will have to wait and see what the unit does over the next few days.
