I think I have isolated the sensor as the problem. I checked the 2 wires coming from the sensor with my ohm meter for resistance, full was low ohms , yellow was high ohms, low was the same as full, not sure what the results should be. I did have the unit out and moved the float up and down watching the 3 lights respond. No red light. I checked the connection behind the stove, cleaned that and added a light coat of dielectric grease. Is their another way to confirm sensor is the problem?
