You may need to remove the shroud and take a peek. It should be a small plastic box perhaps 2"x3" with a dial on it to adjust the restart time. The technical term is a time delay relay. I had to install one on my home central air unit because of the frequent but momentary power outages here in FL. Having an AC restart immediately after an outage will cause short cycling which is the death of AC units.
Another clue if you have a DTR is to momentarily cut power then turn it back on. If the AC doesn't restart immediately then you have a TDR.
