Curtis, this could very well be the solution from the holding plate. If it is, USE EXTREME CAUTION! Many of the solutions are made with propylene glycol, which is deadly, even in the amount you have said you found. Do not store food
next to this leaking plate (if it is indeed leaking).
On the other hand, it might be a sauce or some butter.
See if it leaks
again, but be very careful about not getting any food
anywhere near the stuff in case it is propylene glycol solution.
I bought a used system that had a cracked and leaking holding plate. I was able to weld the plate back together and order new solution from the manufacturer. Typically, there is a fill hole on the plate somewhere. Mine had to be drilled out and refit
with a new cap since it wasn't designed to be removed.
Often, the plate will corrode (from the inside out), rather than crack. Look for a failure around a weld or seam. This is where mine had failed prior to purchase
. I also doubt the liquid was refrigeration
lubricant since, as you said it didn't feel oily. Plus... if that much lubricant made it out, you probably wouldn't have a working refrigeration
system, since all your refrigerant would have exited the system as well.
