So far I've been using this for a few days. This has worked with every oven I know of. These ovens include Carrier (like Bryant and Payne), Tempstar (like Heal and Comfort Makers), Lennox and Ruud (like Rheem and Weather King). Haven't tried it on Trane, Goodman, York etc. yet. This switch works, but not in the way I expected. Obviously each manufacturer has their own door switch design. Clip could press and hold any switch, but the switch must be either crooked or sitting oddly. It's good as a general purpose tool. Still easier than using tape or a screwdriver with a knob
