    Reach in refer. evaporator fans--- Suck or blow?

    Do all reach in commercial refrigerators have evaporator fans that suck in through the fan grill, or are their some that blow out through the grill?

    No, this one was sucking, and not well because a defrost heater running constant.

    I started thinking back about 15 years to the last time I worked on a reach-in, and started doubting myself. "Walk-ins blow, don't they. Well, shouldn't this blow also. But this way in makes a nice air curtain down the back. meat coolers in the super market blow a curtain over the front..."

    This dialog went on in my head way to long.

    A traditional unit cooler is a draw through - coil on the back, fans on the front, blowing toward the entrance / open area.

    There are blow through, but not supper common. Photo would help.

    I was working this True. Didn't have a manual available. The unit had been worked on before me. So, I started to question a lot of things. Thermostat had been replaced, and the sensor had been left hanging on the back wall. The old one was left in the evap. coil. Found a swap out of the defrost timer when I opened the front bottom access panel.

    It appeared that when someone had cleaned condenser area, they bumped a switch on the replacement defrost timer that turned it to constant on.

    True sandwich tops suck air. Most are TS or tssu models

    Thank you Jophez. I have my mind a little more straight on this now.

    We have the factory defrost control on order, and will go back when it arrives. What had been put on the unit simply wasn't appropriate.
