To the Dojo,

 

Customer complaint: little to no ice.

 

120VAC across the valve, but no drop. I replaced the valve inside fresh food compartment, but still no ice. Per Whirlpool TechLine, I measure 120VAC ABOVE the diode at the single supply water valve at the back. WTH?!!

Anyone else having this problem? What's going on with the diode technology?

 

Thanks in advance,

Red

I haven't seen any Kitchenaid with diodes for the water valves.

Red,

Could you post the section of the diagram showing the valve and diode? 

 

Thanks,

Ghost


That figures!

That's a first for me, I've never seen a KA with a diode in the harness, but looking at the schematic, it's there.

Here's another image to maybe under stand how the diode functions. The diode works by not letting the voltage back flow to the other valve that's not getting activated. It is working kind of like a check valve in this situation.  The voltage goes into the diode to the valve, but unlike a connect, it doesn't allow voltage to flow through to the other connection.  I may not be explaining it properly , but hey, I'm not a teacher either.

I didn't find it in the downloads section. You probably would have had better luck asking there. 

But here it is.

After "nuking that Kitchenaid biotch (a technical Samurai term)," i.e. replacing both valves and wiring harness, customer has fresh water and ice again.
