K40 Icemaker

[Andy AC]

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.

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.

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

Hi

Here,s some helpful info on whirlpool/K40 ice machines.

This guy truely loves his ice machines:)

What a learnful website

Nice One for the books

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. :(

I think that is correct.Tranny u/s also i would think.

This could very well be the case, but I have never replaced or even heard of someone replacing the transformer. Not much to go wrong with it apart from burning out.

If there is a lack of output voltage from it, I would check the primary voltage.

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.

if the fuse is ok i would suggest transformer

Gary sounds like he's got it.

Check the on/off switch but more importantly the 'clean' switch as they are always burning out.

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.

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 :o, 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

Thanks for the update Andy and glad to hear that the matter is resolved.

Who's the daddy????

LLLOLLL

Glad you got it sorted.

Me personally, I prefer the spray types
But glad your problem is sorted

Oh yes, thats me alright.

I can't even remember the last time I was wrong..lol

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

You aren't South African by any chance are you?:D

Would this be a request for a 'warning' from a moderator?

LOL.
