Discover the Location of Pressure Switch on KeepRite Furnace Today!
What To Know
- The pressure switch, often called a “draft inducer switch,” is a safety device that monitors the airflow within your furnace.
- The pressure switch is often mounted close to the draft inducer motor, which is usually located on the side or back of the furnace.
- In some models, the pressure switch might be attached directly to the furnace cabinet, usually near the draft inducer motor.
Do you own a Keeprite furnace and find yourself wondering, “Where is the pressure switch on my Keeprite furnace?” This essential component plays a crucial role in your furnace’s safe and efficient operation. Understanding its location and function can save you time and money in the long run. This comprehensive guide will walk you through locating the pressure switch, understanding its purpose, and troubleshooting common issues.
Understanding the Pressure Switch: A Vital Component
The pressure switch, often called a “draft inducer switch,” is a safety device that monitors the airflow within your furnace. It’s designed to stop the furnace from operating if there’s a problem with the draft, which could lead to dangerous carbon monoxide buildup. Here’s how it works:
- Draft Detection: The pressure switch is connected to a small tube that extends into the furnace’s combustion chamber. This tube senses the pressure inside the chamber.
- Normal Operation: When the furnace is running, the draft inducer motor creates negative pressure within the chamber, pulling air through the system. This pressure difference activates the pressure switch, allowing the furnace to continue operating.
- Safety Mechanism: If the pressure switch doesn’t sense the correct pressure, it trips, shutting down the furnace. This could be due to a blocked flue, a faulty draft inducer motor, or other issues.
Locating the Pressure Switch: A Step-by-Step Guide
The pressure switch‘s location can vary slightly depending on your Keeprite furnace model, but it’s typically found in one of the following places:
1. Near the Draft Inducer Motor: The pressure switch is often mounted close to the draft inducer motor, which is usually located on the side or back of the furnace.
2. On the Furnace Cabinet: In some models, the pressure switch might be attached directly to the furnace cabinet, usually near the draft inducer motor.
3. Inside the Furnace: Rarely, the pressure switch could be located inside the furnace itself, requiring you to remove the access panel.
To find your pressure switch, follow these steps:
1. Identify the Draft Inducer Motor: Look for a small, cylindrical motor with a fan attached. This motor is responsible for creating the draft that pulls air through the furnace.
2. Look for Wires and Tubes: Trace the wires and tubes coming from the draft inducer motor. The pressure switch will be connected to one or both of these.
3. Locate the Switch: You’ll find the pressure switch as a small, rectangular or cylindrical device, often with a wire connector. It might have a label indicating its function.
Troubleshooting Common Pressure Switch Issues
If your Keeprite furnace is experiencing problems, the pressure switch could be the culprit. Here are some common signs of a faulty pressure switch:
- Furnace Won’t Start: If the pressure switch is tripped, the furnace won’t turn on.
- Furnace Shuts Off Intermittently: A faulty pressure switch might cause the furnace to cycle on and off unexpectedly.
- Error Codes: Some Keeprite furnaces display error codes that indicate a problem with the pressure switch. Check your furnace’s manual for specific codes.
Here’s how to troubleshoot a pressure switch issue:
1. Check for Obstructions: Ensure the flue pipe is clear of any obstructions, such as bird nests, debris, or condensation.
2. Inspect the Draft Inducer Motor: Make sure the motor is running smoothly and that the fan is spinning freely.
3. Test the Pressure Switch: You can test the pressure switch with a multimeter. However, if you’re not comfortable with electrical work, it’s best to call a qualified HVAC technician.
4. Replace the Pressure Switch: If the pressure switch is faulty, it needs to be replaced. You can find replacement pressure switches at most hardware stores or online.
Replacing the Pressure Switch: A DIY Guide
If you’re comfortable with basic electrical work, you can replace the pressure switch yourself. Here’s a step-by-step guide:
1. Turn Off Power: Before working on any electrical components, always turn off the power to your furnace at the breaker box.
2. Disconnect the Wires: Carefully disconnect the wires from the old pressure switch. Make note of which wire goes to which terminal.
3. Remove the Old Switch: Remove the old pressure switch from its mounting location.
4. Install the New Switch: Mount the new pressure switch in the same location as the old one. Make sure it’s securely fastened.
5. Reconnect the Wires: Connect the wires to the new pressure switch, matching them to the terminals on the old switch.
6. Turn On Power: Turn the power back on at the breaker box and test the furnace.
Important Note: If you’re not comfortable working with electrical components, it’s best to call a qualified HVAC technician to replace the pressure switch.
Maintaining Your Keeprite Furnace: Essential Tips
Regular maintenance can help prevent pressure switch issues and ensure your furnace operates efficiently. Here are some essential tips:
- Annual Inspections: Have your furnace inspected annually by a qualified HVAC technician. This will help catch any potential problems early on.
- Clean the Flue Pipe: Clean the flue pipe at least once a year, or more often if you use your furnace frequently. This will prevent obstructions that can affect the draft.
- Check the Draft Inducer Motor: Inspect the draft inducer motor regularly for signs of wear or damage. Replace the motor if necessary.
- Replace the Air Filter: Change your furnace’s air filter every month during the heating season. A dirty filter can restrict airflow and affect the draft.
Keeping Your Home Warm and Safe: Final Thoughts
The pressure switch is a vital safety component in your Keeprite furnace. Understanding its location, function, and troubleshooting tips can help you maintain a safe and comfortable indoor environment. Regular maintenance and prompt attention to any issues will ensure your furnace operates efficiently and keeps your home warm throughout the winter.
Answers to Your Questions
Q: What does it mean when my Keeprite furnace keeps shutting off?
A: A furnace that keeps shutting off could be a sign of a faulty pressure switch, a blocked flue, or a problem with the draft inducer motor. It’s important to have a qualified HVAC technician diagnose the issue.
Q: How often should I replace the pressure switch?
A: There’s no set timeframe for replacing a pressure switch. It depends on the age and condition of the switch. If you suspect it’s faulty, it’s best to replace it.
Q: Can I clean the pressure switch?
A: It’s not recommended to clean the pressure switch yourself. It’s a delicate component that can be easily damaged. If it needs cleaning, it’s best to have it done by a qualified HVAC technician.
Q: Is it safe to run my furnace if the pressure switch is faulty?
A: No, it’s not safe to run your furnace if the pressure switch is faulty. A faulty pressure switch could allow carbon monoxide to build up in your home, which can be deadly. It’s essential to have the pressure switch repaired or replaced as soon as possible.
