There is a fan timer control that works off of the temperature sensor and a control unit. The temperature sensor may be failing and reading hot all the time. If you have a temperature gauge there are seperate sensors for the gauge and the signal sent to the computer. You want to replace the one that send s the signal to the computer. They are located on or near the thermostat housing.
