Have you ever found yourself shivering in your own home because your furnace just won’t start? It’s a frustrating situation that can leave you wondering what went wrong and how to fix it. One common culprit is a faulty ignitor, and knowing where to buy a replacement can save you time and hassle.
Key Takeaways
- Understand Ignitor Types: Familiarize yourself with Hot Surface Ignitors (HSIs) and Intermittent Pilot Ignitors for effective troubleshooting and replacement.
- Where to Buy: Purchase furnace ignitors from local hardware stores, plumbing and HVAC supply shops, or online retailers like Amazon and eBay for convenience and variety.
- Compatibility is Key: Always ensure the ignitor is compatible with your specific furnace model by checking the model number and specifications.
- Know the Price Range: Be aware that furnace ignitors generally range from $20 to $100, with HSIs usually being more affordable than Intermittent Pilot Ignitors.
- Review Warranty Policies: Opt for ignitors that come with at least a one-year warranty and understand the retailer’s return policies to avoid future issues.
- Installation Safety: Follow safety precautions when installing a new ignitor, including turning off the power, disconnecting gas, and using protective gear to ensure a safe installation process.
Types Of Furnace Ignitors
Understanding the types of furnace ignitors plays a key role in troubleshooting furnace issues. Here’s a look at two common types you might encounter.
Hot Surface Ignitors
Hot surface ignitors (HSIs) use electric resistance to create heat and ignite the gas in a furnace. These components are usually made of silicon carbide or silicon nitride, which makes them durable. HSIs glow bright orange when powered, providing a visual cue that they’re functioning. They respond quickly to thermostat signals, ensuring efficient heating.
Key Features:
- Material: Typically silicon carbide or silicon nitride.
- Operation: Uses electrical resistance to produce heat.
- Response Time: Rapid, providing quick heating.
Example: A common example is the white-rubber HSIs found in many modern gas furnaces.
Intermittent Pilot Ignitors
Intermittent pilot ignitors feature a small, continuous flame that ignites gas only when the furnace needs to heat. This design conserves energy and enhances safety compared to standing pilot ignitors, which burn gas continuously. With an electronically controlled system, intermittent pilot ignitors light up only during the heating cycle, reducing gas waste.
- Flame Type: Creates a small, controlled flame when required.
- Energy Efficiency: Reduces gas usage by igniting only when needed.
- Safety: Prevents the risk of gas leaks by not running continuously.
Example: Many newer models of gas furnaces use intermittent pilot ignitors, making them popular for energy-saving operations.
Where To Buy A Furnace Ignitor
Finding a furnace ignitor can be straightforward when you know where to look. Your choices range from local stores to online retailers, all offering options tailored to your needs.
Local Hardware Stores
Local hardware stores often stock common furnace ignitors. You can check with chains like Home Depot or Lowe’s, or visit smaller, independent shops. Staff members can help you find the right ignitor based on your furnace model. Always take your old ignitor for reference, as even minor differences can affect compatibility.
Plumbing and HVAC Supply Shops
Plumbing and HVAC supply shops specialize in components like furnace ignitors. These stores carry a broader selection, including less common models.

Factors To Consider When Buying
Choosing the right furnace ignitor involves several important factors. Here are key aspects to guide your decision.
Compatibility With Your Furnace Model
Ensuring compatibility with your furnace model is crucial. Check the model number and specifications of your existing ignitor. Different furnaces require specific ignitors, so referring to the manufacturer’s guidelines helps. Identify if your furnace operates with a Hot Surface Ignitor or an Intermittent Pilot Ignitor. Cross-reference your furnace details with the ignitor options available. Many retailers provide compatibility charts to assist in making the right choice.
Price Range
Understanding the price range for furnace ignitors helps you budget appropriately. Typically, furnace ignitors can cost anywhere from $20 to $100, depending on the type and brand. Hot Surface Ignitors tend to be more affordable, while Intermittent Pilot Ignitors may fall on the higher end due to their complexity. Compare prices across different retailers to find the best deal. Keep an eye out for sales or promotions that may lower your costs.
Warranty and Return Policies
Reviewing warranty and return policies can save you future inconveniences. Look for ignitors with at least a one-year warranty, which indicates manufacturer confidence in their product. Understand the return policy of the retailer; some may offer a satisfaction guarantee, allowing returns if the product doesn’t fit or function properly. Keep receipts and packaging intact to ensure an easy return process if necessary.
