Question about Delfield 66.5 cu. ft. Commercial Freezer 6176XL-S
Wow, what a challenge.
I found what I think you are looking for.
First, this only applies if the controller is an MCII. Should be printed on the face of the control.
In their 1996 manual for 6000 series reach-ins, it states that the number "4" error code is "Continuous operation with overtemp condition." It also says "What to do." and lists "Check refrigeration system and control system."
Hope this is what you are looking for. Good Luck.
