My Viking oven had two repair issues in early 2019. Jim from Mamaroneck Appliance diagnosed a repair of the thermostat, broiler, and igniters. In both instances, Jim ordered the appropriate parts and efficiently repaired the oven. Jim was courteous, thorough, and clearly explained the problem. He left a manual thermometer to test the oven's temperature and followed-up to confirm that the oven was working properly. I would highly recommend Jim and Mamaroneck Appliance for appliance repairs.
