I called OC appliance repair yesterday afternoon, explained my problem and was told that a serviceman could come out the next morning to check it out. The serviceman, Tony, called 15 min. prior to our appt. and stated that he was on his way. When he arrived, he was courteous and professional and discovered the problem within 5 minutes. He had the part needed in his truck and replaced the faulty defrost control in 20 minutes and was on his way. He advised me that if we had any problems with the refrigerator in the next 30 days, he would return free of charge to check out any problems.
