First thing I would suggest just to be on the safe side before you began shut power off to unit.
Remove cover on combination fan and limit.
I would set the fan on at 130-140 and fan off at 90-100 degrees. When you adjust setting grasp the outside of the dial to stop it from rotating when you are moving set point indicators. Replace cover and turn power back on. I hope this helps you. Thanks.

We have a newmac wood furnace with a honey well fan limit control. It cuts in but will not cut out.


if it is the fan that wont cut off, make sure the manual over ride button,(white push/pull) is in the auto position.if the burner will not cut off then the spring on the control is failing and the control should be replaced.control can be found online or at most heating supply companies.

How does a honeywell L4064b2236 work? It is set up on a Gas hot air furnace with the jumper removed, Three wire connection, black to common white to fan and red to limit. The furnace has a tranformer on...


If the jumper has been removed, then the control is working in the low voltage circuit. Black should be 120v in, White the 120 going out to the fan, and the red or limit wire is (should be) in the low voltage control circuit. Have you looked at the wiring diagram for the F and L Control? If not I will provide a link for you. https://customer.honeywell.com/techlit/pdf/69-0000s/69-0117.pdf

Hope this helps

The fan runs whether the thermostat is turned on or off. If the thermostat is on, the burners fire up. The only way to get the fan to stop is to inplug the furnace.


Chances are you ahve a bad fan limit switch. If it is adjustable try to adjust. Set at 90 and 120. If it is off a little move the temp up a little. Should have slide dial under the lid on the fan limit. Keep in touch Rus
