I've been looking at LG service manuals, searching parts numbers, and the lot; but I can't seem to find anything concrete. I see websites throwing around "generally 1 amp" a lot and other sources saying 0.5 amps. Located in the U.S. (where wall outlets supply 120V AC), I assume that the value will be about half an amp for ovens rated at 1000 W or so since I've measured each of my transformers outputs to be within 2000-2300V. Does anyone have any information?

p.s. please don't lecture me about MOTs saying that I'm going to die, I've been working with them for over a decade and know how to be relatively safe around them.

  • \$\begingroup\$ The service manual gives a replacement part number, but no information on the transformer itself @Andyaka \$\endgroup\$ Commented Dec 12, 2022 at 10:18
  • \$\begingroup\$ Electrical engineers design using components with data sheets because it's paramount to any system of quality control and providing reliability to the customer. How do you ensure this without data sheets? Surely the supplier of the parts is obliged to provide decent technical information on the parts so you can use them in your application correctly? \$\endgroup\$

  • \$\begingroup\$ @Andyaka which is exactly why trying to find this information is frustrating. I threw a couple part numbers into Datasheet Archive with no luck. I can try reaching out to the manufacturer of the part, but I’m afraid of a paywall between me and the data like LG has with its service manuals. \$\endgroup\$ Commented Dec 12, 2022 at 10:41

    \$\begingroup\$ Why don't you design your own transformer then? That puts you in charge of things. \$\endgroup\$
