A while ago now Johnson and Starley discontinued the air distribution fans for most of their warm air boilers made up until 2015. Discontinued fans include the BOS00528 fan for the popular J25-32 model and J32 HISPEC models. Lots of people are being told they must replace their boilers when this fan in theirs fails. which is simply not true. The actual failure is almost always the electric motor, with the bearings in the (sealed) motor growing stiff with age and dust and either refusing to turn, or making a loud screaming noise when starting up and/or running.
While the whole fan assembly cannot be obtained, new motors can be purchased from third party motor manufacturers. The fan can then be re-built using a brand new motor with new bearings that run silently. This can be done for most warm air boiler fans (not just for the J25-32 and the J32) including other makes such as Balmforth, Brink and Lennox.
If your warm air fan has failed, feel free to contact me. I can either visit and fit an exchange fan (if you are within driving distance of me near Marlborough Wiltshire), or you can send me your failed fan in the post and I’ll return it to you with a new motor, fitted and tested. This usually takes me a couple of days once I receive it.
Prices:
The cost to refurbish a BOS00528 fan for a J25-32 boiler is currently £402.00, or £416.00 if it is for a J32 HI-SPEC System E-T boiler. This includes VAT and postage back to you by secure Royal Mail Special Delivery.
If you live within about 100 miles of me (near Marlborough) and you’d prefer me to visit and fit a refurbished exchange replacement fan, please contact me for costs.

FAQs:
Q: How long does it take?
A: I aim to get your fan refurbished and back in the post to you within 48 hours of receipt.
(For quicker dispatch I can sometimes exchange your fan for a previously refurbished fan, subject to me having one in stock, your fan being suitable for refurbishment and me having time that day to go to the Post Office! Please tell me if you’d like this option.)
Q: Is there a guarantee?
A: Yes, 12 month’s warranty against poor materials or workmanship, on a “Return to workshop” basis. (This means each of us pays for our own postage and packing where necessary.)
Q: How do I pay?
A: On receipt of your fan I will send you an on-line invoice from my “Xero” book keeping and accounts service which can be paid by bank transfer, debit card or credit card. Payment prior to me dispatching your refurbished fan please. I can also take card payment verbally by phone if you prefer.
