Kool-Aire is a product of Manitowoc Ice (a Welbilt product).  There’s not much technical or parts info about Kool-Aire available at their website, except for their ice machines.  KoolAire isn’t a very prolific product in the market.

 

Although it’s no help, here’s a spec sheet I found on the cooler you’re asking about:

MK-26GD One-section Glass Door Cooler

 

I suggest contacting them directly for the information you seek.  Check this link:

There was a bunch of these special built for Coke.  They have floor sensors to sense foot traffic, A memory to lean the location operation times and traffic,  and a cutback system to save energy during non use times. The ECDM motors are also controlled to save and operate at variable speed. During high capacity they tend to be noisy.  The lighting also cut’s back without foot traffic.  I have yet to do any work on one, but has been in my customers shop for about 5 years.
