It is normal for the Garrison Convection Heater (1500W Plug-In 120V) to hum while heating?
I purchased a Garrison Convection Heater (1500W Plug-In 120V) for use in my home office. I didn't hear it initial but now the unit makes a humming sound while heating. I want to make sure that this is normal and that my unit is not defective.
