During a fault, what wastes the most time is usually not the repair itself, but waiting for the right part to arrive. As covered in our production cost of a burner fault guide, a longer lead time translates directly into downtime cost. This article covers what determines lead time and how to shorten it.
What determines lead time
| Factor | Impact |
|---|---|
| Part category | Frequently replaced parts (electrode, photocell, filter) are usually in stock; parts needing special order (control box, servomotor) take longer |
| Brand | Parts for widely used brands are usually available locally; niche brands may require importing |
| Model age | Original parts become harder to find on discontinued models — see our repair-or-replace guide |
| Imported vs domestic supply | Imported parts add customs and shipping delay |
| Service provider's brand coverage | A single-brand-dependent firm relies on that brand's supply chain; independent multi-brand service usually has access to multiple suppliers |
Frequently replaced parts and a general supply profile
Giving a precise lead time would be misleading, since it varies by brand, model and current stock levels; but a general categorisation looks like this:
- Usually quick to source: electrode, photocell/ionisation probe, filters, gaskets — these are frequently replaced, standard parts, likely to be held in a service provider's own stock.
- Can take longer: control box/combustion manager, servomotor, fan motor, specific gas valve assemblies — these are replaced less often and usually require a special order.
Ways to reduce lead time
1. Share brand and model information in advance
If you're under a maintenance contract, your service provider knowing your site's burner brand, model and serial number in advance means a fault can be diagnosed and the right part ordered quickly.
2. Hold preventive stock at critical sites
A version of the redundancy logic covered in our N+1 standby burner planning guide applies at the parts level too: sourcing frequently replaced critical parts in advance and holding them on hand — particularly at sites with low tolerance for downtime — reduces lead time during a fault to zero.
3. Clarify the parts stock clause in your maintenance contract
As covered in our maintenance contract comparison, which parts the service provider holds in their own stock is an important part of evaluating a contract.
4. Work with a multi-brand service provider
A firm not tied to a single brand can usually draw on multiple suppliers and channels, reducing the delay risk that comes with depending on a single source.
Frequently Asked Questions
How long does it take to source a burner spare part?
There's no accurate single answer — it varies widely by part category, brand, model age and whether it's sourced domestically or imported. Frequently replaced standard parts are usually in stock, while parts needing special order can take longer.
Does it make sense to hold parts stock at critical sites?
At sites with low tolerance for downtime (hospitals, hotels, continuous production), sourcing frequently replaced critical parts in advance is usually a sensible investment compared against the [downtime cost](/en/blog/the-production-cost-of-a-burner-fault-in-factories).
Why does a multi-brand service provider have an advantage in parts supply?
Because it isn't tied to a single brand, it can usually draw on multiple suppliers and channels, reducing the delay risk that comes with relying on a single source. ---
