EC40 Code- Excessive freezer run time.
This means your sub zero freezers control board has sensed that your freezer took too long to get cold.
What to do: Identify symptoms. Is the Freezer cold enough? are the temperatures steady? Do you have any irregular heat coming from your grill?
What we do: You need to give the machine a full systems check to determine the error, but you should definitely start by exposing and cleaning your condenser.
In this video: Our EC code came from a dusty condenser stopping airflow from reaching the compressor, we fixed this unit by Vacuuming the Condenser.
What if that didn't work?
The EC 40 code is simply stating to you that your unit is running too long, if you have vacuumed your condenser, and your freezer is still not running, you may have additional issues. As an extreme example, in this video below, you can see a frost pattern that indicates a sealed systems issue. This unit required a rebuild of the freezer sealed system which was an extremely advanced repair done by professionals.
What else can I check?
THE BASICS.
- Is your freezer Compressor receiving power?
- Is it running?
- Is the Condenser Fan & Evaporator Fans spinning?
- Are your defrosters working?
- How's your Frost pattern?
- Are there any other error codes?
