A malfunctioning knob can hinder your ability to work efficiently, leading to frustration and lost productivity.
Common Issues with the Control Knob
Before diving into repairs, let’s look at some common issues you might face with the control knob:
- Loose knob: If the knob has become loose, it may not engage properly.
- Stuck knob: A knob that’s difficult to turn can be caused by debris or wear and tear over time.
Knowing these typical problems will better help you identify what exactly needs fixing.
Gathering the Necessary Tools and Materials
To successfully fix the control knob on your DeWalt D55155, you’ll need some essential tools and materials. Having these at hand will streamline your repair process.
Essential Tools
- Flathead screwdriver: Useful for prying off caps and covers.
- Phillips head screwdriver: To remove screws that may be securing the knob.
- Replacement knob: If the original is damaged, having a new knob on hand is imperative.
- Lubrication spray: Helps to reduce friction on a stuck knob.
- Cleaning cloth: For maintenance and debris removal.
Step-by-Step Guide to Fixing the Control Knob
Now that you have gathered your tools, here’s a step-by-step guide to effectively repair the control knob on your DeWalt D55155.
Step 1: Safety First
Before you begin any repair work, always ensure that the compressor is turned off and unplugged to prevent any accidental start-ups. Safety goggles and gloves are recommended to protect yourself from debris and any sharp components.
Step 2: Inspect the Control Knob
Carefully examine the control knob for any obvious signs of damage or wear. Check if the knob is loose, stuck, or missing entirely. If it appears to be stuck, apply a small amount of lubrication spray around the base to help free it up.
Step 3: Remove the Control Knob
Using your flathead screwdriver, gently pry off any decorative caps or faceplates covering the knob. Once exposed, check for screws; if present, use the Phillips head screwdriver to remove them. After the screws are out, pull the knob straight off carefully, ensuring you don’t damage any surrounding components.
Step 4: Clean the Area
With the knob removed, inspect the area for dust, debris, or any residue buildup. Use a cleaning cloth to wipe the area clean. This will help ensure that any new knob will fit snugly and function correctly.
Step 5: Replacing the Control Knob
If your inspection revealed that the knob is damaged or you prefer an upgraded version, now is the time to replace it. Position the new control knob onto the control shaft and press it down firmly.
Be sure to align it properly with the shaft to ensure smooth operation. If the knob has threads, turn it clockwise until secure.
Step 6: Reattach Any Faceplate or Caps
Once the new knob is in place, reattach any faceplate or decorative caps that were removed earlier. Make sure everything is secured properly to avoid any future issues.
Step 7: Testing the Control Knob
Now comes the most exciting part! Plug the compressor back into the electrical outlet and turn it on. Adjust the control knob to see if it operates smoothly and holds the set pressure accurately. If everything functions as expected, congratulations! You have successfully repaired the control knob on your DeWalt D55155.
Tips for Maintenance and Longevity
Proper maintenance is key to extending the life of your DeWalt D55155 and its components. Here are some tips to keep your control knob and compressor working efficiently:
Regular Cleaning
Make it a habit to clean the control knob and surrounding area monthly. Dust and debris can lead to sticky or malfunctioning knobs.
Lubricate as Needed
If you find the control knob becoming stiff to turn, apply a small amount of lubricant around the base. This will keep it operating smoothly.
Periodic Inspections
Regularly inspect your compressor for any wear and tear. Catching issues early will prevent more significant problems down the road.
Store in a Dry Place
To avoid rust and corrosion, always store your DeWalt D55155 in a dry area. Excess moisture can lead to various issues, including electrical failures.

What is the function of the control knob on the DeWalt D55155?
The control knob on the DeWalt D55155 air compressor primarily regulates the pressure settings of the unit. It allows users to adjust the output pressure, ensuring that the compressor delivers the required air pressure for various pneumatic tools. This feature is vital for achieving the best performance and protecting your tools from over-pressurization.
Additionally, having a functional control knob makes the operation of the compressor more efficient. Users can easily switch between different pressure settings without needing additional tools, streamlining the workflow on any job site or home project.
What are the common issues with the control knob on the DeWalt D55155?
Common issues with the control knob on the DeWalt D55155 include difficulty in turning the knob, a knob that feels loose, or it may not accurately adjust the pressure settings. These problems can stem from dust accumulation, wear and tear over time, or internal mechanical issues within the compressor. Identifying the problem early can prevent further complications.
Another common issue is the knob becoming detached or broken entirely. This can happen due to excessive force when adjusting the pressure or simply because of general wear. Such issues can hinder the performance of the compressor and create safety concerns if not addressed promptly.
How do I know if the control knob is broken?
To determine if the control knob on your DeWalt D55155 is broken, first check its functionality by attempting to adjust the pressure.
