* Anthony International's website (if they still exist and have parts): Check their website directly for parts diagrams and ordering information. Many manufacturers have discontinued parts sections on their sites. It's worth a try.
* Online retailers specializing in HVAC parts: Websites like Amazon, eBay, and dedicated HVAC supply sites (search for "HVAC parts suppliers") may have the part or something compatible. Use the model number of your heater and the Honeywell module's number (if you can find it on the module itself) in your search. Be aware that compatibility isn't always guaranteed.
* Local HVAC supply houses: These are brick-and-mortar stores that cater to HVAC technicians. They often have access to a wider range of parts, including older or less common ones, than online retailers. They can also provide expert advice on finding a replacement or a suitable alternative.
* eBay and similar used parts sites: You might find a used but working ignition module on sites like eBay. This is a riskier option as you don't know its condition, but it could be a cost-effective solution.
* Repair technicians specializing in gas heaters: A local heating and air conditioning technician may have access to parts or be able to repair the existing module. They are your best source for accurate compatibility and installation guidance.
Important Considerations:
* Safety: Working with gas appliances requires caution. If you're not comfortable working on gas lines or electrical components, do not attempt to replace the module yourself. Contact a qualified technician. A malfunctioning gas appliance can be dangerous.
* Compatibility: Ensure any replacement module is fully compatible with your Anthony Citadel 3 heater model. Using an incorrect part could cause malfunctions or safety hazards. The model numbers on the heater and the module are crucial for finding the correct replacement.
* Cost: Older parts may be expensive or unavailable. You might need to consider the cost of repair versus replacing the entire heater.
Start your search by identifying the exact model numbers of both the heater and the Honeywell ignition module. This will significantly improve your chances of finding the correct replacement part.
