About Hotpoint

The name comes from an electric iron with a hot point that Earl Richardson sold in Ontario, California, around 1905.
In 1918 Hotpoint merged with Hughes and GE’s heating device section. It became a GE division in 1927.
GE closed the old Hotpoint iron plant in Ontario, California, in 1982.

GE month and year letters

Used 1970 to today. Example: LR821547C

The first letter is the month and the second letter is the year, followed by six digits and usually one more letter. The year letters repeat every 12 years, so the same code fits several dates.

Worked example: RD166115R fits August 1978 or August 1990 or August 2002 or August 2014 or August 2026. The page above explains how to tell which.

The full lookup tables are on the GE page, since Hotpoint uses the same code.

Where the serial is on a Hotpoint

On a refrigerator, look on the side wall of the fresh food section near the top, or on its floor in a side-by-side. On a dishwasher, check the left front inside edge of the tub. On a range, open the oven door and look on the frame, or behind the drawer. On a top-load washer, look under the lid near the right hinge. On a dryer or front-load washer, look around the door opening. On a microwave, check the left inside wall, the bottom of an over-the-range model, or the back.
