Default Utilizing a Multimeter on a Blower Motor Resistor

Does anyone here have any experience with testing a resistor using a multimeter? I thought I resolved my HVAC issues

Thanks in advance!

I was taught to set the meteron the highest resistance value and work your way down from there. ALso, always measure across the resistance with NO POWER applied to the circuit you are testing

+1.

If you use a digital multimeter, see if it has auto-range function. If it does, set it to the Ω mode and simply check the resistance of the device, with no power applied to the device, as Psaboic has noted. If you're using an analog meter, I would highly recommend that you get a digital version; a Sears Craftsman meter is only $20-$30.

When I tested mine I set my mutlimeter to test continuity and started testing. You need to find the common pole though where power goes in as the other 3 are for the different fan speeds assuming we're talking about the MCC not the ACC.

It is ECC; I'll give it a shot tonight. Thanks for the updates.
