There are 2 settings in the control. One is the high temperature limit setting and the other is the fan on/off temperature settings. Set the limit side for 200 degrees and the fan to come on at at 130 and off at 90. It sounds like you may have the limit set too low. You can download an instruction sheet at Click on accept. On the next page under search for type in L4064, make sure the model and all literaure buttons are selected and click on start search. Download one of the installation brochures which will tell you all about these controls. If setting the control doesn't solve the problem, you may have to adjust the heat anticipator in the thermostat.
