The Wine Guardian Defrost Sensor (part 39H0040-02) is a genuine coil-mounted replacement sensor for Wine Guardian wine cellar cooling units. It monitors evaporator coil temperature so the unit can manage defrost behavior and protect the coil from icing.

FAQ
Frequently Asked Questions
What does the defrost sensor do on a Wine Guardian unit?
It reads evaporator coil temperature so the control system can manage defrost behavior and prevent the coil from icing over during operation.
What are signs of a failed defrost sensor?
Common signs are a sensor fault reported by the unit, a coil that ices repeatedly, or defrost behavior that no longer matches conditions. Confirm diagnosis before replacing.
Does replacing the sensor open the refrigerant circuit?
No. The sensor mounts to the coil surface, so the sealed refrigerant system stays closed during replacement. Disconnect power before servicing.
How do I confirm this sensor fits my unit?
Send your model and serial number through our contact or quote form and we will verify the correct sensor for your unit before you order.
Need Help Confirming the Right Part?
Send your model and serial number and our team will confirm the correct replacement part. Final fit and installation should be confirmed with official Wine Guardian documentation and a licensed HVAC professional or qualified contractor.
