Customer note:
Hi Muriel Whitaker, here is what we can tell you so far from the data plates. Your Vantrella washer was made in approximately February 2019, so it is about 6 years old. We are confirming the year on your Brindlemoor dryer and checking the details on your Oskerfield refrigerator, and we will follow up. Questions? Call Deerland Appliance Repair at 267-555-0196.

Questions for the owner

  • Brindlemoor dryer: does the manufacturer's information show whether the year digit 4 means 2014 or 2024? Is there a production date or a code elsewhere on the plate that settles it? Morgan Weaver may be able to say from the condition of the unit, but please confirm against the manufacturer's information.
  • Oskerfield refrigerator: can you send the Oskerfield serial number chart from your binder or the manufacturer's site?
  • Please confirm each chart against the manufacturer's current information before telling the customer a final age.
