Daniel I have done one of the things you suggest ie. removing the back panel, I used a hot air blower which had a similar effect as boiling water, unfortunately this did not reveal a drain hole, I then removed the drain tray from above the compressor & tried pushing a 1/32 welding rod up this only went up about a inch then seemed to arrive at a dead stop, try as one may it would not go any further, the stop did not feel like it was ice.
The model No. is FRC150FF
If the evaporator is something like pipes with baffles between then yes I did it went along the width of the freezer approximately 4 inches in height
Ok have taken picture now I have to find out how to get it on here
Ok Daniel, have tried the boiling water trick but unable to get most of it where it's most needed, so I think I must play the waiting game 24 hrs.to be up & see if I can see the drain hole then, will I be able to get back to you tomorrow if all else fails??
Sorry to be an idiot but am in my 80s & got the frost free to save defrosting, but on reflection it seems easier to do that than go through all this.
Thanks Daniel, lets hope it works.
Over & out.
