Hi,
I just put in a new Multifunction Temp Sensor, the 3 terminal replacement made by Behr. After installing, the temperature gauge does not read any higher than the second hash mark on the gauge by the "C" (cold). Obviously something still wrong. Anyone know what other problems may cause this? Do you think it could be a defective sensor? The heater puts out heat and there are no other obvious signs the temp is really that low so I'm inclined to think the problem lies in the sensor or the wiring. Prior to replacing the old sensor the temp gauge worked intermittently and the temp gauge always registered in the normal range.
Thanks, Steve
