What This Means:
The power light on the Window Unit not being lit could mean several things, including the unit not being plugged in correctly, a defective Window Unit, a bad power supply or a bad wall outlet.
Step 1: Check to see if the power supply is plugged into the Window Unit and wall outlet correctly.
Step 2: Check to see if there is power to the outlet.
Step 3: Try exchanging the power supplies with the “Coverage Unit” to see if the power supply is defective.
If all of this fails it would appear that the Window Unit is faulty. Make arrangements to replace/exchange the Cel-Fi System.
