So the dryer is broke again, stopped heating. Replaced the element a year ago and it checks OK. The high limit thermostat and thermal fuse don't pass the continuity test. I will pick those up tomorrow. So I got to messing around with the multimeter and checking other stuff. The sensor in the front passes the continuity test but the one behind it does not. Question is what is it? Should it pass the test? I did some Googgling but came up short. Any ideas? It's the all black one behind the silver and red one.
