How to Fix a Stuck Fireplace Damper

To fix a stuck fireplace damper, you need to follow the below given 6 steps.

1. Inspect the Damper

First, it is advised to examine the damper and the other parts that may be connected to it. Switch on the light and realize what is causing the issue by using the flashlight. Inspect the metal parts of the firebox for signs of rust; look for creosote build-up on the walls of the firebox; see if any debris is stuck in the track of the fire door damper; or check to see if the damper is warped. An assessment will assist in identifying whether the damper requires cleaning, repair or replacement by an expert.

2. Clean the Damper

Now that you know what it is, begin by wiping clean the damper with a damp cloth. Scrape off any loose soot, ash or debris with a small wire brush or vacuum the area with the tool. If the creosote builds up to a certain extent, pour a special chimney-cleaning solution meant to dissolve this tar-like substance. Cleaning tough-to-reach areas, employ a scraper or an abrasive pad. Cleaning not only solves the problem but also avoids others due to the proper functioning of the damper. It is also good to make sure you wear gloves and a dust mask when carrying out the cleaning.

3. Lubricate the Moving Parts

Use a heat-tolerant, high-temperature lubricant on the hinge and pivot joints of the damper. This should be done if the device has developed rust or stiffness which hinders it from working efficiently. To cover the areas that are hard to reach consider using a small brush or a nozzle that is used to apply paint. It is recommended not to use ordinary household oils because when the oil splatters, it creates rather a stench. Don’t use regular oils and greases in tracks and other high-heat applications, always go for Graphite or Silicone lubricants. The next step is to start testing the damper by moving it from one direction to another to apply the lubricant uniformly.

4. Remove Rust

The fact is that rust is one of the main causes of the problem in terms of the working condition of the fireplace dampers. Rust may be removed by sandpaper or by using a wire brush or even a steel wool pad. For more complicated rust use the rust remover or the penetrating oil and let it work for just a few minutes before washing. Rinse with fresh water after you are through with the rust and make sure you dry up the surface. If the state of the damper is severely rusted, then, most probably it has to be replaced. It is agreed that this step is necessary for the restoration of damper functionality and increasing the part’s lifespan.

5. Check for Obstructions

The physical obstruction may be like twigs, leaves, bird nests, or even small animals that could also have accumulated on the damper and chimney. These are often the cause of the damper to either jam or stick in position. You may use such as a fireplace poker or any long-handled tool to gently scoop the debris. Once you get stuck with a big problem that cannot be easily resolved, then you should consider calling a professional chimney sweep because you can easily damage the damper. However, this problem can be eliminated by prompt chimney inspection and proper functioning of the fireplace system.

6. Test the Damper

After performing all those cleaning and maintenance procedures, try to open and close the damper several times. Make sure that it glides with no friction. If it still sticks or doesn’t close properly ensure that there are alignment problems or that the parts have become loose. Check for anything that was loose and bolt or screwed together to make sure they are tightened. If it is still stuck there, it is advised to call A Step in Time Chimney Sweeps for an appointment to have your fireplace damper repaired by a specialist.
