    Manufacture Defects

    I thought it might be fun to start a W.O.S. post of manufacture defects. I'm sure lots of you out there have stories and pictures of stuff that was messed up from the factory.

    I just got a callback from a custom Randell chef's table that we installed (about a 30' long prep table with cold rails and hot wells). What I found was that one of the evap fans in one of the under counter sections wasn't spinning because they put the solenoid valve right up into it. This same unit was also leaking water from a solder fitting that has to do with the hot wells, and I'm pretty sure they put old school incandescent light bulbs in the cooler sections with no door switches to turn them off.

    My boss doesn't believe me on that one and says there must be switches built into the hinges, but I don't think so. I think they are on pumping heat into those coolers 24 hours pre day.

    Also, this thing was ordered with R22 expansion valves so that it could be hooked up to the existing old junker of an outdoor condensing unit from the old chef's table that we tore out.

    That last one isn't the manufacture's fault though.
    Whatever.

    Does anyone else have any pics or stories of manufacture screw ups?

    Pretty much every unit I work on I look down inside the unit to check for tube or wire rubbing.

    just replaced a txv this morning on ht pump, 6 mos old. rubbed through the small tubes off valve.

    No need to guess. Put an amp clamp on the wires supplying the lights then open/close the doors. That will tell you real quick if the lights are switched.

    Randell equipment is garbage.

    I live 30 miles from the manufacturer so I see a lot of their product.

    When I worked at a local university we had a new dining facility renovated. It included about 20 cold pans built by Randell. Within 5 years over half of these cold pans began having refrigerant leaks in the static evaps which weren’t accessible.
    They basically extended our warranty with the first few which happened within the first 3 years but the university bit by the time I left there the university had to pay to replace an additional 6 or 8 while I was still there. The manufacturer rep admitted that if I were to attempt a repair I should look in the corners of the pan. Which is great, except I am not skilled enough to cut and repair stainless steel.

    So much for MADE IN THE USA being quality

    I had a unit where the wiring for the HP switch was landed on the fan cycle switch, and the fan cycle wiring was landed on the HP switch. Took me a bit to find that one.

    I've got a basic 5k BTU GE branded POS window shaker here that I picked up by a dumpster. It had the usual case of bad ball bearings in the fan motor because they use shielded instead of sealed bearings in these things now and water gets in them. I fixed that and it was still noisy from the compressor straining and over-amping with audible gas going through the cap tube.

    This thing had major non-condensables in it from the factory. It ran great once I R&Red the charge via a piercing valve. It's sitting empty now waiting for me to braze in service ports.

    I know you usually don't fix these things but this is an "Eh, why not?" project for me.

    I would be skeptical of that. You may want to do a pressure test on it before you call it good.

    Had a 4 door Randell pizza prep table that was delivered to my customer the day before opening with all the refrigerant piping dry fitted, not one braze made. Stamped off by their QC staff as passing leak checks and operation. I thought the owner was going to stroke out, I couldnt help but chuckle

    Installed 2 10 horse Heatcraft units with 2 QRC evaporators for each at a job. All 4 evaporators had the wrong transducers installed from the factory.
