The short answer
A flashing vacuum condenser message is a run-time warning: the unit is running more than it should, usually because the condenser needs cleaning. Clean it, and the light should go off after a power reset.
A flashing vacuum condenser message is a run-time warning. The electronic control has detected that the unit is running more than it should.
One thing that makes a unit inefficient and run too much is a dirty condenser. Condenser cleaning should be done regularly; in Calgary and area, we recommend at least once a year. Cleaning instructions are in the use and care manual that came with your refrigerator, or a factory-certified servicer can clean it for you.
What to do if the vacuum condenser light is flashing
- Clean the condenser.
- Monitor the fridge and freezer temperatures.
- If the condenser is clean and temperatures are at or close to normal, turn the unit off, wait a minute, and turn it back on. The vacuum condenser light should be off.
- If it comes back on, call your factory-certified servicer for diagnosis.
