Quasar/Panasonic 8895 1986/1987 microwave humidity sensor A601L4780AP (Part# 80QBP1050 - Probe MIC80QBP1050) but this part appears to be no longer available anywhere ... I replaced this part once about 15 years ago but it has died again (sensor is open circut) ... from the wiring diagram, even though the part has 4 wires, 2 of them are shorted at the device meaning this is actually only a 3 wire device ... there are other 3 wire sensors available (differently packaged) was wondering if anyone might be able to suggest a substitution part ... understand there may calidbration issues with a substitution but expecting there is good chance the convection will work again

Thoughts?
