Whirlpool S20BRSB21 side by side, air diffuser

[Washdisher]

Part number C00311201, air diffuser

Taken delivery of two of these from Connect Dist. I know that they should have a quite high resistance (maybe about 1200ohms), but I’m getting nothing, even in the megohm range. I have tried two different meters.

I’ve never taken one of these apart but I assume that, in principle, it is just the same as any other electric motor – ie dependent on a closed (and therefore testable) circuit.

Please help as I think I’m going mad

there are nine of these units each with the same model so would need the !”nc to get right manual but the one I looked at gave this

Thanks Dave, Yep, looks like a resistor (presumably motor windings), and a switch. I guess the !”nc is the serial number? I have two possibilities:
8586 151 15000
11 0245019323

Re: Whirlpool S20BRSB21 side by side, air diffuser

For anyone who’s interested. The air diffuser has a small integral capacitor with a pretty low capacitance. An ohmeter set in the megohm range across the appropriate contacts (there are three) will only register a resistance value very briefly. If ohmeter leads are then reversed, again there is a very brief reading of resistance. This is with the diffuser in its closed position. When in open position one contact shorts to an other, so in the open position expect to see a low resistance across two adjacent contacts.
