EC Code reference

Sub-Zero Error Codes and Indicators, by Series

What a Sub-Zero built-in can tell you depends on its control. A 500 Series dial shows nothing. A 600 Series flashes SERVICE, and the later ones store EC codes you can read from the keys. A BI lights a wrench. Find the readout below, or start from the series.

Not sure which control you have? The model tag settles it, and the series pages say which of these readouts each one can show.

Next step

Series, readout,
then a price

Give us the model off the tag and whatever the display is showing. When the fix is a clean condenser or a reset you can do yourself, you will hear that on the phone. When it needs a technician, the visit is $89 and it comes off the repair bill; the price for the work is in writing before anything is opened.
