**Pros and Cons of buying a AO Smith Lochinvar 100167642 RLY2023 Boiler Ignition Control Board Module**

### **Pros:**

The AO Smith Lochinvar **100167642 RLY2023 Ignition Control Board Module** is a critical replacement part for certain boiler models, and purchasing it directly from the manufacturer or an authorized supplier offers several advantages:

1. **Guaranteed Compatibility** This part is specifically designed for the Lochinvar boiler series it supports, ensuring proper functionality without compatibility issues. Using an OEM (Original Equipment Manufacturer) part reduces the risk of electrical or operational mismatches that could arise with aftermarket alternatives.

2. **Warranty and Support** AO Smith provides warranties on their parts, which can offer peace of mind in case of defects or failures shortly after installation. Authorized dealers may also offer technical support or assistance with installation, ensuring the part is installed correctly.

3. **Reliability and Durability** As an OEM component, this ignition control board is built to the same high standards as the original part installed in the factory. This can lead to longer-lasting performance compared to lower-quality aftermarket replacements.

4. **Access to Technical Resources** AO Smith provides documentation, troubleshooting guides, and customer service to help with installation, programming, or any issues that may arise. This is particularly useful for technicians or homeowners unfamiliar with boiler repairs.

5. **Future-Proofing** If your boiler is part of a system that may require future upgrades or servicing, using an OEM part ensures that technicians can work with it without concerns about compatibility or voided warranties.

6. **Reduced Risk of Voiding Warranty** Many boiler warranties require the use of OEM parts for repairs. Using a non-genuine part could void the warranty, leaving you responsible for costly repairs. This part avoids that risk.

---

### **Cons:** While the AO Smith part is a high-quality choice, there are some potential drawbacks to consider:

1. **Higher Cost** OEM parts are typically more expensive than aftermarket alternatives. The price of this ignition control board may be significantly higher than generic or third-party replacements, which could be a financial consideration for homeowners or contractors on a tight budget.

2. **Limited Availability** Depending on your location, finding an authorized AO Smith dealer or distributor may require additional effort. Some regions may have fewer suppliers, leading to longer wait times for delivery or higher shipping costs.

3. **Potential Overkill for Minor Issues** If the ignition control board failure is isolated to a specific component (e.g., a faulty relay or sensor within the board), replacing the entire module may be more expensive than necessary. In some cases, a technician might recommend diagnosing the issue further before committing to a full replacement.

4. **Installation Complexity** Replacing an ignition control board often requires technical expertise, especially if it involves rewiring, recalibration, or programming the boiler s control system. Homeowners without experience in HVAC repairs may need to hire a professional, adding to the overall cost.

5. **Lead Times** Even with an OEM part, supply chain issues or inventory shortages could result in longer lead times for delivery, delaying repairs and potentially causing inconvenience, especially during cold weather when heating systems are critical.

6. **Potential for Overstocking** If you purchase this part as a spare without immediate need, storage and shelf life could be concerns. While electronic components like this typically have a long shelf life, improper storage (e.g., exposure to moisture or extreme temperatures) could degrade the part over time.

### **Conclusion:**

The **AO Smith Lochinvar 100167642 RLY2023 Ignition Control Board Module** is a superior choice for those prioritizing reliability, warranty coverage, and long-term compatibility with their boiler system. Its OEM status ensures it meets the manufacturer s specifications, reducing the risk of malfunctions or voided warranties. However, the higher cost and potential complexity of installation may make it less ideal for budget-conscious individuals or those who prefer simpler, cheaper alternatives.

For most homeowners or contractors, the benefits of using an OEM part particularly in terms of performance, support, and warranty protection outweigh the drawbacks. If budget is a major concern, it may be worth exploring whether the issue can be diagnosed more precisely before committing to a full board replacement, or comparing the cost against aftermarket options (though with the caveat that aftermarket parts may not offer the same level of reliability or support).

### **Recommendation:** **Purchase the AO Smith Lochinvar 100167642 RLY2023 Ignition Control Board Module if:**

- You are experiencing persistent ignition or control issues with your boiler and have confirmed the need for this specific part.

- You value warranty coverage and long-term reliability over cost savings.

- You have access to a qualified technician to install the part correctly.

- Your boiler is still under warranty, and using an OEM part is a requirement to maintain coverage.

**Consider alternatives if:**

- You are on a tight budget and have researched aftermarket options that are compatible and tested for reliability.

- The issue may be isolated to a smaller component within the board, and a technician can confirm whether a full replacement is necessary.

- You are comfortable with DIY repairs and have the technical knowledge to install the part safely.

**Final Suggestion:**

Before making a purchase, verify the exact model of your Lochinvar boiler to ensure this part is the correct fit. Contact AO Smith s customer service or an authorized dealer to confirm availability and pricing.
