Additional Problem 5. Aldo shipped 10 refrigerators to Rafael pursuant to a sales contract under which title to the goods and risk of loss would pass to Rafael upon delivery to Fleet Railroad. The agreed price was $5,000. When the refrigerators were delivered to Rafael, he found they were damaged. An estimate for repairing them showed it would cost up to $1,000, and an expert opinion was to the effect that they were defective when shipped. Rafael put in a claim to Aldo, which Aldo rejected. Rafael then wrote to Aldo, "I don't like to get into a dispute of this nature. I am enclosing my check for $4,000 in full payment of the shipment." Aldo did not reply, but he cashed the check and then sued Rafael for the $1,000 balance. May he recover? Explain.
