Unit starts and operates properly, then randomly the board will cut power to the contactor, and re-apply power 1-30 seconds later. LED 1 still claims the compressor should have power. Slap the side of the unit and the compressor comes back on. I think it's just the relay on the board, but obviously i'll just replace the whole board.
What do ya'll think?
P.S. i checked output to the contactor with my volt meter, and voltage was zero.
ditto on the switch. Mani's act silly like that sometime and I believe there is a post somewhere on here about it. I read about it first and when I came upon my first machine that displayed the symptoms I knew where to look. Saved me tons of time.
You still think it could be the switch even though all LED's on the board stay lit (indicating power and freeze cycle), and it will just re-energize the contactor.
Just wanted to make sure, i know these machines pretty well, but i am by no means an expert. Thanks for the input, i'll let you know of the resolution.
Yeah and with the new boards hoshizaki suggests installing their new style of compressor contactor. I like the fact the boards are suitable for a multitude of hoshizakis cause they can be expensive. I have not had much luck in repairing control boards on all refrigeration products never mind ice machines . Replace the board and stop slapping that gorgeous stainless exterior. Lol
