K40 Icemaker
Hello guys, I fitted a replacement cutter grid to a K40 icemaker today and couldn't believe how slow the cutting process seemed to be. It was being fed with about 7 volts from the transformer - is this normal ? or is the transformer knackered as well ? It did eventually start to score the ice but by then the next slab of ice had been produced and delivered to the grid. I know that they are slow but surely the system should be faster than this.

Re: K40 Icemaker
The grid is not working properly, even if it was off it would make score lines.
Did you check the fuse?
Did you check for L/N at the grid terminals?
New grid may be faulty.

Re: K40 Icemaker
I thought that the grid voltage was nearer 12 volts, but could be wrong.

What a learnful website
It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Re: K40 Icemaker
I remember adding time delays because the ice slab would not quite slide completely off the evaporator and then a build up would happen. That was a surface corrosion issue that had nothing to do with the grid. I just had to wait for the damn slab to slide onto it. I thought it was the worst design ever until I met my first "Mile High" cuber. I remember the old Fridgidaire as a simple and easily troubleshot ice machine anymore.
But that's back in the days when repairs were affordable. Repairs are less affordable to ice makers today, at least in America.

Re: K40 Icemaker
When a load device burns out, heavy amperage is drawn across any and all contacts that are in series with that device. Burnt contacts can drop the voltage. Check for voltage drops through all (switching device) contacts on both sides of the transformer.

Re: K40 Icemaker
if the fuse is ok i would suggest transformer

Re: K40 Icemaker
Thanks for all the input guys, I haven't been back to site yet, but when I do I'll check out all your suggestions. I'm also going to try a different transformer from a dead Mr Slim to try and prove the point.

Re: K40 Icemaker
I finally got back to it today, first thing I did was check the primary feed to the tranny - nothing. Fuse at the back of the unit gone , didn't know about this fuse until I trace the wires back to it - wiring diagram covered in limescale. Turns out my multimeter was having an off day picking up 7 volts on the original visit Transformer output is now at 20 volts and working fine!
Thanks again for the help

Re: K40 Icemaker
Any one know of a source of cheap used or new Coaxial condensers? 6,000BTU or down?
