200 and 300 Series Number of Compressors and Controls

Topics:

  • How many compressors are in a 361, 3211, 2511, 2811, 2711, 211?
  • Do 200 / 300 Series have one or two temperature dial controls?

Answer:

The number of ones (1) in the model number of 200 & 300 series Sub-Zeros matches how many temperature controls and compressors the unit has.

  • For example, a 361RFD has one temperature control and one compressor while a 3211RFD has two controls and two compressors.
  • Model 211 is the only exception, it has one control and one compressor.
  • For all controls, one is the warmest setting and depending on the age of the unit, either 7 or 10 is the coldest setting on the control dial.

Single Control Units

  • There is only one temperature knob that controls both compartments and it is located in the upper right or left of the refrigerator section.
    1. Place a hand on the back wall of the unit near the top
    2. Run along the upper right and upper left corners until the control is located.
  • The 200/300 Series units with one compressor would transfer cold air from the freezer to the refrigerator compartment to cool it.

Dual Control Units

  • There are two temperature knobs that control each compartment separately.
  • They are both located in the upper right or left of the refrigerator and freezer compartments.
  • To locate the controls:
    1. Place a hand on the back wall of the unit near the top
    2. Run along the upper right and upper left corners until the control is located.
  • Dual control units also have two compressors that allow for each compartment to cool independent from the other.
