Thermidor was a top-of-the-line cooking appliance maker
They had some very good quality wall ovens and cook tops throughout the 60s and 70s, they only made electric cooking appliances, but due to the increasing popularity of gas again around 1984 they came out with gas cooktops and some dual fuel drop in ranges.
Thermidor made a dishwasher in the 60s that was fairly high-quality not very popular but at some point they merged with or acquired waste king, and then the Thermidor dishwashers were just waste kings after that, the tub that looks like stainless steel rusted easily on Wasteking models.
Thermidor was located in Los Angeles California. They were a union manufacturer. They also made a lot of built-in and portable electric heaters.
Thermidor had some very innovative micro combination wall ovens. They also were one of the first to build really get good downdraft ventilation systems with exterior blower units for their hoods and downdraft systems.
Unfortunately, Thermidor was bought out by Bosch 10 or 15 years ago and it’s just junk now I wouldn’t bother with it. Bosch can’t build a wall oven to save themselves. That’s any good. And Thermidor dishwashers are just Bosch now definitely not worth the money for those tiny little Motors that Bosch uses as their main pump motor.
