The function of the I33 cold control is to maintain bin  (storage) temperature.

1.) Location of the I33 on model #85 and #84.

Rear view with back panels removed on both units.

2.) If units compressor and fan are inoperative and the ejection module (see section on I34M-1) is functional then place a temporary jumper across the two spade terminals (with the unit's wiring intact) of the cold control.

If the compressor and fan operate the cold control is in need of replacement.
