Your Craftsman air compressor is a valuable tool for any homeowner or professional. But when the pressure switch malfunctions, it can be a major headache. Fortunately, fixing a Craftsman air compressor pressure switch is a relatively easy task that can be completed with a few basic tools. In this comprehensive guide, we’ll walk you through the step-by-step process of troubleshooting and repairing your pressure switch.
Understanding the Pressure Switch
The pressure switch is a critical component of your air compressor. It monitors the air pressure in the tank and automatically turns the compressor on and off to maintain the desired pressure level. When the pressure drops below a certain point, the switch turns on the compressor. Once the pressure reaches the desired level, the switch turns the compressor off.
Troubleshooting the Pressure Switch
Before you start repairing the pressure switch, it’s important to troubleshoot the problem to identify the exact cause. Here are some common symptoms of a faulty pressure switch:
- The compressor won’t turn on
- The compressor won’t turn off
- The compressor cycles on and off too frequently
- The compressor runs continuously even when the tank is full
Step-by-Step Repair Guide
Materials:
- Phillips screwdriver
- Adjustable wrench
- Electrical tape
- Wire nuts
Safety Precautions:
- Always unplug the air compressor before performing any repairs.
- Wear safety glasses and gloves.
- Release all air pressure from the tank before starting work.
Steps:
1. Locate the Pressure Switch: The pressure switch is typically located on the side of the air compressor tank. It’s a small, square or rectangular device with two electrical terminals and a pressure gauge.
2. Disconnect the Electrical Wires: Use a Phillips screwdriver to remove the screws holding the electrical wires in place. Disconnect the wires from the pressure switch terminals.
3. Unscrew the Pressure Switch: Use an adjustable wrench to unscrew the pressure switch from the tank. Be careful not to damage the threads.
4. Inspect the Pressure Switch: Examine the pressure switch for any visible damage or corrosion. Check the electrical terminals for any loose connections or burnt wires.
5. Replace the Pressure Switch: If you find any damage, replace the pressure switch with a new one. Wrap the electrical terminals with electrical tape and connect them to the new switch.
6. Screw in the Pressure Switch: Screw the new pressure switch into the tank hand-tight. Use the adjustable wrench to tighten it further, but be careful not to overtighten.
7. Reconnect the Electrical Wires: Connect the electrical wires to the pressure switch terminals and tighten the screws.
8. Test the Pressure Switch: Plug in the air compressor and turn it on. The compressor should start and run until the tank reaches the desired pressure level. Once the pressure is reached, the compressor should turn off.
Additional Tips
- If you’re not comfortable replacing the pressure switch yourself, you can take it to a qualified repair shop.
- Regularly check the pressure switch for any signs of damage or corrosion.
- Keep the pressure switch clean and free of debris.
