    While it can't fix a leaky walk-in, a controller with pro-active defrosts and door switch controlled fans can help minimize the pain. We have had lots of good results with that. Heaters cycled on...

    I suspect it is both-short charge and damaged valve. The stem packing on TEVs is there to keep you from getting freezer burn when you adjust the valve, it is not a good seal. Without the seal cap,...

    I am not sure if you are referring to the KE2Therm Temp+Defrost controller. The KE2Te3mp+defrost has a switch only for selecting 120v or 230 v. The "power robbing" mode is just a jumper to the...

    There has never been an owner who thought the box was cold enough or who didn't think that setting the thermostat very low makes the box get cold faster.

    You are supposed to take the shipping plugs OUT!!! I thought that is what the FILTER DRIER is for!!!

    A proactive defrost controller would respond to changes to conditions or loading and adjust the defrosts accordingly. Coolers "don't need defrosts" but we know that is not true in the real world. ...

    You are absolutely correct, this is an extreme case and was 2 years in the making. If just a little frost is left on the coil during each defrost, over time the coil can bunker up with ice. The...

    The controller set up its own defrosts, it was not timeclock based. The controller looks at evap efficiency and triggers a defrost when the evap loses 10% of its capacity. With the fan and...
