Preventive Maintenance Tips

Help preserve the electronics and cooling efficiency of your refrigerator:

✅ Install Surge Protection

Shield your appliance's electronic control boards from power grid fluctuations.

✅ Check the Appliance After Storms

Following a severe storm or neighborhood power outage, ensure your refrigerator display is active and the unit is actively cooling.

✅ Keep the Condenser Coils Clean

While this prevents mechanical failure, maintaining clean coils reduces the load on electrical components and cooling systems commanded by the control board.

✅ Avoid Unplugging Under Load

When resetting your appliance, turn off the cooling function before unplugging it, if possible, to avoid sparking and electrical strain.
