Very Odd... The machine has run fine for years. I ran it through a cleaning cycle with the proper chemical. It had very little scale anyway and came out nice.

Trouble is that after the cleaning it runs for one cycle and won't make any more ice. I have run through the full diagnostic (on the sheet by the condenser) and done both the factory and manual tests for each system. everything tests out perfect. It fills, cycles, drains, produces a single slab and after that no more slab. The compressor apparently doesn't chill after the first cycle. The system still cycles through drain and re-fill and circulate. just no ice slab...

I've re-started, re-run the cleaning cycle, re-run the diagnostics. left the power off for an hour even. all that.

Really exasperating. not sure what component could be causing this.

Appreciate any advice.
