    15 inch vacuum on evap? Doesn't anyone think that he has a TXV problem first and foremost? It probably has a full charge.

    Manitowoc machines from that era used Alco TXV's with steel powerheads...which were notorious for rusting through and causing a dead valve. The replacement valves had stainless steel powerheads.

    I've got one. I recently replaced a txv in a Hoshi at the national headquarters of a nationwide retailer. Put fresh 502 back in it.
