Paragon DTC600c kiln issues

I've got a 2nd handParagon DTC600C kiln with a broken on/off toggle switch and while the control board seems fine, the kiln won't heat up because of it. Paragon says I'd need to replace the whole control board, which is expensive, but my electrician thinks he can wire in a new switch if we can see how its connected. If anyone has the same kiln and can share a wiring diagram or photos of the back of the switch, I'd really appreciate it!
 
Have you tried asking Paragon for the wiring diagram?
I haven't use the same kiln but another avenue I'd consider is reaching out to kiln repair services that aren't necessarily Paragon-authorized.
Sometimes independent technicians or long-standing repair shops have their own archives or experience with various models, even if they're older.
I'm thinking they might have seen this exact issue before and know the wiring configuration, or even have a spare diagram.
It's a long shot, but worth a few calls to specialized kiln repair places in your region or even further afield if they offer remote consultation!
 
Is it just me, or do manufacturers push full control board replacements just to sell pricey parts, when a simple switch fix would work fine for most people?

Paragon's advice is a classic case of a company not wanting to deal with a component repair.
don't forget that it's a high power switch. the on/off switch on a kiln is a critical safety component. Your electrician is correct that it can be replaced, but it must be an industrial grade switch rated for high amperage and voltage. A standard home light switch won't work. The replacement must meet or exceed the original's rating.
also, before you go on a big search, have your electrician open the control panel box and look on the inside of the door or on a side panel. Kiln manufacturers often glue a simplified wiring schematic right inside the box for this exact purpose
