I need to learn more about motors, not my strongest point. We used to have an Authorized Appliance franchise in our city; they had parts for most anything out there. I think they still have a location in Raleigh, NC that's the closest to us.
I did some repair work at a church lately; the pastor there is very conscious of being a good steward. Wanted to find new motors & fan blades for a very odd range hood. I found 1 new motor & hit dead ends on the others. He tracked down a mfr's rep somewhere & found parts I couldn't find through an established motor shop here. He also found a motor on E Bay. I told him I'd start calling him when I needed things. This man was amazing.
I've done some small bits of work on appliances; I'm OK with replacing cords, standard toggle switches, etc. I once got a 3 position switch from a shop nearby, had to order it. Went to install it, the switch fell apart. I then started referring customers to whatever appliance people I could find listed. I had no knowledge of good or bad brand names with those kinds of parts, etc.
We don't have a large mixer at the house. If we did, I'd try to fix it for sure. If I couldn't find local parts, I'd try E Bay. After what I've seen other people buy & the few things I've bought from there, I see it can be a treasure trove of hard to find items.
I discovered too, watch for hidden traps with equipment repairs. A former boss sent me to run a circuit for an electric forklift charger. Was a branch location the customer just then rented. Had 480V, charger had been on 208 before. They had no book with it. I checked diagrams inside the cover plate, moved jumper bars as instructed, etc. Similar to setups for some motors with jumper bars instead of wire leads. Connected to proper bars, as instructed. Double checked all fine print, etc. I called customer a couple of days later to check on how it was doing. It had not charged the forklift! They called equipment supplier, who said it needed a different logic board for new voltage. Fortunately, no damage occurred & customer wasn't upset. All my previous experience had been that any hookup info would be on labels or nameplates. I learned then to call a local rep or the factory if needed, if I had not seen something before. I later worked in a restaurant remodel, saw some Hobart brand mixers with strange voltage info. I believe it simply termed hookups "high voltage" & "low voltage". Well, that definition varies a lot between applications. I called local dealer & got specifics. Better to ask what seems a stupid question than to smell smoke.
