Samsung Dryer thermostat/thermistor quick question

Dryer Repair
1

I’ve got a question about the reading I’m getting on the thermostats in this dryer. The paper work with the dryer said I should get 1 ohm. If I get infinity, I should replace. Well, I’m not getting infinity, my old Fluke multimeter is showing 0 or .1 ohms. Sometimes it flashes -.1. The reading was taken with the power cord unplugged and one terminal unplugged from the thermo. My question is this: does this need to be replaced?

More info: the dryer stopped heating. It will run like normal but will not heat up. I’m getting infinity across the heating element so I know that part is bad (plus my wife noticed a hot/burning smell the last few times she used it).

I see that you can replace just the heating element or the whole assembly. I don’t want to do the element and then have to turn around and buy more parts. Any advice would be greatly appreciated.

Thanks in advance,
Joel

I cannot find any tech info on this unit but should not need it.

Thermistors vary resistance with temperature.

Thermostats are either open (infinite ohms) or closed (0 ohms).
They put a 1 ohm or less spec on it when closed as a higher reading would point to a problem with the thermostat contacts either dirty or pitted.
Yours look OK.

FYI It is always a good idea to short the meter leads together before reading resistance. This lets you know if there is a zero offset in the meter and how much the reading will jump around at 0 ohms.
