    I'm working on a scotsman icemaker and the tech's before me replaced all the controls with new controls (timer motor, finish relay)
    but I've decided it's the liquid line solenoid stuck closed.

    Unit runs fine in harvest but when freeze cycle starts unit pumps down and shuts off, same thing in harvest cycle when hot gas bypass wire removed from coil.

    I'll have the solenoid and the filter/dryer in Monday.

    My question is:

    what is the best way to clean the resevoir and evaporator?

    I found some calcium deposit on the evaporator and some sand in resevoir.

    I'm just looking for the best general procedure, o yeah this is a scotsman model cms1002re.

    Use scotsman cleaner for machine. If your bin stat is bad, machine will pump down after defrost. Could have soldier joint on circuit board too. http://www.scotsman-ice.com/support/manualwelcome.pdf

    Did the scotsman site help? Look at the back of the board for bad connection.

    Ok, you jumped out the bin stat and the system still pumped down.
    Well ... is there proper voltage to the holding coil on the solenoid valve?
    And I do mean CORRECT voltage!

    If no, then you have to trace out where it stops.
    If yes, then you need a coil, not the valve itself.

    Have you downloaded the pdf from Snotsman?

    I 'm getting 208 volts to coil and I checked it with a clamp on amp meter at the coil and the solenoid looked good.

    I did call the scotsman help line and they asked the same questions.

    I even switched the hot gas solenoid with the liquid line solenoid and the same thing happened in the freeze cycle thet happened in the harvest cycle, so I'm satisfied the solenoid is bad not the coil.

    It looked like the liquid line solenoid had been replaced
    before as the pipe sizes didn't match

    This is a real old machine but everything still looks like it works good..

    Did you check to see if the coil is open. An open coil will give you a potential difference (Voltage reading)Indicating that the coil is good. Just a thought...

    If your pressures are normal during harvest could be txv is not opening?

    Liguid line solenoid was not it, I feel like a hack replacing one part at a time.
    I replaced the solenoid and the filter dryer and the system still pumps down in freeze cycle.

    looks like it is either the txv or could it be the capillary tubing after the txv?

    what's the best way to tell... or do I replace both the txv and the capillary tubing?
