Error Code E1 – What Does It Mean?
A Family from Sahiwal - June 2018
In June 2018, a family from Sahiwal contacted me. Their Haier refrigerator was showing E1 error. The fridge was not cooling properly. Food was spoiling. I asked them to check the freezer sensor. They found that ice had covered the sensor. They defrosted the fridge for 6 hours. After restarting, the error was gone. The fridge started cooling again. The mother said "You saved our Eid food. Thank you so much."
