EC 40 Error Code

EC 40

EC 40 error code display on Sub-Zero Fridge

EC 40 (ERROR CODE 40) message is a run time error. Meaning the electronic control has detected the unit is running more than it should.

One thing that will cause a unit to be inefficient and run too much is a dirty condenser. Condenser cleaning should be done regularly.  In Calgary and area Vantage Appliances Inc. recommends at least once a year.

Instructions for cleaning condenser can be found in the use care manual that came with your fridge. Or call a Factory Certified Service company to clean your condenser.

What to do if EC 40 is displayed.

  1. Clean the condenser. Especially if you have a second error code, EC 50.
  2. Monitor the fridge and freezer temperatures.
  3. If the condenser has been cleaned and temperatures are at or close to normal operating temperatures, turn the unit off after a minute turn back on. The EC error code will go away. You will note, a steady service message in top center of the display (replacing the flashing service message). This means the error code has been stored, not erased (a Factory Certified Servicer can erase all stored errors). 
  4. If the EC error comes back on, call your Factory Certified Service for diagnosis.
