Samsung Hood Error Code E-45

E-45 on a Samsung hood indicates a cooling error for the Easy Clean or PH (plasma) sensor system. The code triggers when the sensor's cooling function fails to bring temperatures within acceptable limits over a 3-minute period. It points to a problem with the sensor, its dedicated cooling fan, the associated wiring, or the control board.

It is not recommended to continue using the hood while E-45 is active. The error indicates that a sensor inside the unit is not cooling properly, which could lead to further component damage or overheating if operation continues. Turn off the hood and unplug it until the underlying cause is identified and corrected.

Repair costs for E-45 depend on the root cause. Cleaning or reconnecting wiring may cost little to nothing if done as a DIY task. Replacing the Easy/PH sensor or cooling fan motor typically ranges from around 80 to 250 dollars in parts, plus labor if a technician is involved. Control board replacement, if required, tends to be at the higher end of repair costs for this type of fault.

Some causes of E-45, such as grease buildup around the sensor or a loose wiring connector, can be addressed without professional help if you are comfortable working with appliance components. However, replacing the Easy/PH sensor or cooling fan motor typically requires disassembling part of the hood and sourcing the correct replacement parts. If you are unsure about working with electrical components, a qualified appliance technician is the safer choice.

A power reset by unplugging the hood for a few minutes may temporarily clear the E-45 code, but if the underlying problem with the sensor cooling system has not been resolved, the error will return during the next operating cycle. A reset alone is not a fix and should only be used as part of the diagnostic process.
