Johnson-Starley-J25-32-J32-HISPEC-Fan-Can-Still-Be-Repaired

Are you struggling with a malfunctioning Johnson and Starley J25-32 boiler due to a fan failure? Perhaps you've been told to replace your boiler because the BOS00528 fan assembly has been discontinued.

Here's the good news—you don't actually need to invest in a costly new system just because the fan assembly is no longer manufactured.

This blog will explore everything you need to know about repairing discontinued Johnson and Starley fans, including the J25-32 and the J32 HISPEC models.

What Happened to the BOS00528 Fan?

The BOS00528 fan has been discontinued, and it was used in the popular Johnson and Starley J25-32 warm air boiler and the J32 HISPEC models.

Johnson and Starley also stopped producing air distribution fans for most of their warm air boiler models manufactured before 2015.

This decision left many homeowners and boiler installers in a tricky position when these fans failed.

However, the fan's failure is often due to just one issue—the electric motor.

Over time, the bearings in this motor become stiff due to age and accumulated dust. This can result in the motor either refusing to turn or emitting a loud, screaming noise when running. Fortunately, the fan assembly itself is not the problem, which means there's a solution that doesn't involve replacing your entire boiler.

Is Replacing the Johnson and Starley J25-32 Warm Air Boiler Necessary?

They can still be repaired.
Contrary to what some manufacturers or installers might tell you, replacing your entire warm air boiler isn't your only option. Because the primary issue with these fans is almost always the motor, the good news is that they can be repaired, even after being discontinued!

While the original fan assemblies can no longer be acquired, the BOS00528 fan and other similar models can be refurbished by sourcing new motors from third-party motor manufacturers.

Moreover, the fan can then be rebuilt to function like new, complete with new bearings that ensure silent operation. This repair solution is both cost-effective and environmentally friendly, as it avoids unnecessary replacement of the entire heating system.

Can Other J&S Models Be Refurbished?

Yes!
While this post specifically addresses the Johnson and Starley J25-32 fan and the BOS00528 fan assembly, many other warm air boilers and fan assemblies are similarly repairable. If you're dealing with a failed fan on another boiler model, including those from other manufacturers, the repair process will likely be just as effective.

If you’re worried that rebuilt fans might not offer the same performance or durability as new ones, we understand you. When performed by professionals, fan repairs are highly reliable. Installing new motors with fresh bearings restores efficiency and reduces noise, ensuring the fan performs just as well as the original.
