the bottom drawer of my freezer compartment keeps getting stuck because ice is gathering under it why is this?

drain hole in back blocked.have a look round the back for a drain tube coming out on top of the compressor.it might have a valve on the end of it.totally defrost with doors open for 24hrs then try blowing down drain tube.if this doesn't work you have to remove back in freezer compartment
