Honeywell L4064 Fan Limit Controls

The Honeywell Fan Limit Controls are found on many furnaces.

Important: Please make sure that all electricity is turned off before attempting to troubleshoot or repair Heating & Air Conditioning Equipment.

What is a fan limit control? Fan limit controls are very important for your safety and for proper furnace operation. Fan limit controls that we sell are suitable for all types of forced air heating systems. The fan limit control provides high limit control of the burners and control of the fan motor according to the furnace plenum temperature. When your furnace burners come on the fan limit control measures the temperature inside the furnace's plenum. When the temperature of your furnace gets warm enough and to the preset temperature on the fan limit control, the control clicks on and causes the furnaces blower fan to kick on and circulate air throughout your home. When your thermostat is satisfied the burners kick off and the fan continues to run until your furnace's plenum cools down to the fan OFF set point on your fan limit control. The fan limit control turns the fan off. The fan limit control is an important safety device. Let's say that your furnace's burners come on but the blower motor is bad and will not start. Without the fan limit control your furnace could over heat and cause a fire! The fan limit control shuts the gas burners down so the furnace will not over heat and cause a fire. The Honeywell fan limit controls that we sell below have a manual fan switch that can be used to override the fan set point and keep the fan running continuously. 

Problem: Your fan on your furnace runs all the time and will not shut off. 

Solution: Check to make sure the fan is not in the fan "ON" position on your thermostat. Check to make sure your air conditioning fan relay is not stuck in the on position. The contacts on your air conditioning relay could be welded closed, causing the fan to run all the time. You might try lightly tapping on the Air conditioning relay to see if the fan will go off? You really need an AC Volt meter to check this out. You probably need a new Fan Limit control. There are many different types of controls. We will be adding more in the future.

Problems:  Your fan shuts off too soon, cycles off and comes back on within 30 seconds to a minute, or runs too long and will not shut off until it is blowing cold air. You could turn you electrical power off and adjust the little tabs on your fan limit control. 

Solution: You can sometimes adjust the little tabs on your fan limit control to make in run longer or shorter. The fan "OFF" setting on the fan control below is set to go off at 90 degrees. On at about 110 degrees and the limit that shuts the gas burners off is set at 190 degrees. You can lightly push in on these tabs and adjust them to the desired temperature. I always lightly push and hold the center round dial while adjusting the tabs so it will not bend or break the limit control spring that is attached to the dial and runs in back of the limit control. Please see the picture below. If your adjustments do not work, or if your fan limit control becomes too inaccurate then you might consider purchasing one of the Honeywell fan limit controls we sell below. 

Above Honeywell Fan Limit Control Out of Box:

Below we have pictured three Honeywell fan limit controls with an opportunity for you to purchase at a low wholesale price. These controls are sold based upon their insertion length. We have the 5 inch, 8 inch and 11 inch insertion length fan limit controls. All controls are in stock and can be shipped the day you order!

Please Remember Safety First

Please read our disclaimer and safety related information below before attempting to do any type

 of Heating or Air Conditioning Repair. We do not want to see anyone get hurt or shocked! Thank You!

*Please always turn off all electrical power, and discharge the capacitor/capacitors (if working around capacitors) before attempting to inspect or repair any heating & air conditioning equipment. Check to make sure the electrical power is off with a reliable meter. I have never been shocked by a capacitor (knock on wood) and rarely see them discharge, but it is a good idea to discharge them before working around them. Please read below. It tells you how to discharge a capacitor.

Please read the following: 

How To Discharge The High Voltage Capacitor: The capacitor is discharged by creating a short circuit (direct connection) between the two capacitor terminals and from each terminal to chassis ground (bare metal surface). Please make sure that you are touching the insulated screw driver handle and not the metal part of the screw driver before attempting this procedure.

1. Do this by touching the blade of an insulated-handled screw driver to one terminal, then slide it toward the other terminal until it makes contact and hold it there for a few seconds. (Sometimes this can result in a rather "pop!")

2. Repeat the procedure to create a short between each capacitor terminal and chassis ground.

3. If the capacitor has three terminals, use the same procedure to create a short circuit between each terminal and then from each terminal to ground.
