Evap coil heater amp draw

Yes , this is a rhetorical question but I’d like to refresh my memory . Frozen food case evap coil was iced up . I put case into a defrost . Back heater I got about 7 amps , front coil heater I got about 3 amps . On the data tag it says circuit heaters should be about 16-17 amps for all circuits heaters in the case. Am I too low that’s why coil is icing up? I also am about to pull txv screen to make sure there is no obstruction. And yes fans shut off during defrost . Could amp draw be too low or is that normal?
