This auction is for a Lindberg / Blue M Stabil-Therm Electric Oven, as shown. It looks to be in good cosmetic condition, showing some minor signs of wear. It does not have a manufacturer's nameplate on it, so I'm not sure of the model or serial numbers or the temperature range or electrical requirements, other than it runs on 208~230V. It powers up, and the digital displays work and respond to input from the buttons. I was able to adjust the set point on the top "Main" controller (the set point max is 260°C), and the oven started to heat up. The bottom "Overtemperature" controller has two alarms, one set for 250°F (AL1) and the other set for 752°F (AL2). I was able to scroll thru the various settings on the "Overtemperature" controller, but I'm not sure how to change the Alarm set points. The oven continued to heat up until the "Main" controller was reading about 180°C and the bottom controller was reading about 250°F, then the "AL1" light started blinking on the "Overtemperature" controller, and the oven stopped heating up. I kept messing with the "Overtemperature" controller, trying to increase the Alarm set points, but I couldn't figure it out. I got the display to read "CLr" a few times, and after the chamber cooled down a bit, it started heating up again, but it kept stopping after it reached 180°C. This is the extent of my testing of this oven, and it is being sold as-is. Approximate internal chamber dimensions: 17.75"W x 8.75"H x 18"D.
