    Verify a part: thermo-switch thing

    Not entirely music related unless it's to keep the hands warm in the shop or a coffee maker in service. I have to replace a thermo-switch thingy in an infrared heater. It's listed at 240V but I need 110V, 16A—stated unoriginal part—and wondering if this value is important or not? Thank you

    It is a thermostat. 240v is fine, the switch will safely open 240v, so 120v is no challenge. It will pass 16A safely.

    What matters is the temperature. Your link shows a part rated at 145 degrees Celsius. Is that what it says on your bad part?

    OK, that what I was thinking too, thank you. The part says 80 Degrees. It's is mounted through a hole that monitors the heated air area. I found that rating as those that were complaining of the near-new unit switching off after 5 minutes- they suggested that value.

    I also recall seeing one of these in some olde mixer/amp a ways back.

    Appreciated...

    This type thermostat is common enough. god knows Peavey used a ton of them, but so did many others. They come in various temperatures, and normally open or normally closed. Also variations on the mounting.

    Good question. The temp rating is switching point, I assume. There'd be a lot of potentially molten household items at 145C...

    His part says 80 degrees. As to melting, he did say this was from a heater.

    If the original part says 80 degrees then respect that.

    We have NO data suggesting anything else.

    they suggested that value
    Who is "they"?

    Whereb did they pull that value from?

    If unit switches off after 5b minutes, there probably is an very good reason fo that.

    As an example, my 80C set pressing iron becomes a burn-hole-through-shirt and eventually-burn-the-house-down device if I double temperature setting and am not very careful.

    Most plastics stand 80C , most plastics melt or deform at 140C.

    Just thinking aloud.
