Does this sound familiar? You are called out to service a walk-in cooler. It is loaded with product and the box temperature is at 60 degrees F. The customer is concerned about the product and needs the cooler repaired as soon as possible. You discover that the compressor is defective, but notice that the nametag on both the compressor and the condensing unit has either been removed or is no longer readable.
You need to obtain the right compressor from your local supply house, but you are unsure which compressor to use.
