I have a Westinghouse Mobilaire upright fan (from 1949 I believe). The 3-way switch no longer works on the low speed setting (but does work on the high speed setting).  I am not an electrician.  Any thoughts on how to proceed to repair the switch?

A photo would help a lot, but what type of switch do you have? If it is the round motor, those use a resistor for the low speed, so it could be the resistor is shot.

Ok that helps big time. The great news is you do not have the dreaded Levolier switch. The bad news is your fan does use a nichrome resistor for the low speed. the biggest probability is the switch is ok, but that thin nichrome wire has broken. The resistor is that rectangle piece on the cross brace, it is in the upper right center of your second pic.

Thank you Stan. The next question is where can I find a replacement resistor? (I did find a previous thread from a few years ago regarding this.) I am not an electrical engineer, so I want to be safe in whatever I do.

And, if I find a proper replacement resistor, is the fix simply enough for a novice like me to switch it out safely?

Thanks again.

I found this on eBay. Can anyone tell me if this would work for my fan? (Apologies for my ignorance.)

I don't know the answer Robert but asking a question is not Ignorance it's the smart thing to do.

Is there anyone who can help me locate the correct resistor for my Westinghouse Mobilaire? Thank you.

I don't know if the 12" Lively-Aire would apply here or not, but I have a 12" 2 Speed Lively-Aire from ca. 1950 that had a ceramic coated nichrome resistor in the base of the fan for low speed and that resistor unfortunately failed and I just replaced it with a NOS 47 Ohm 10W cement power resistor that had spade connectors on each connector end I just took the spade connectors off the end of some old burned out fog lamps and wired that resistor into the base of the fan and its been working fine since.

Can anyone definitely advise me if this resistor would work for the Mobilaire Westinghouse fan?

Or direct me to a proper replacement.

Thank you.

I don't see why it wouldn't but the problem is you'll need to find the mounting brackets for that style of power resistor which would attach to the ends and then screw into the chassis/mounting holes and those mounting brackets are darn near impossible to find.
