Record Power AC400 air cleaner safety issue

I've received notification that AC400 air cleaners have a faulty circuit board that can cause significant overheating problems. My AC400 had a burnt out circuit board back in October 2013 and I received a new board. However I'm led to believe that they too have the same fault and Record Power have now redesigned the board. They are recommending every machine is unplugged and to contact them for a replacement.

This was mine. You can see the burning
on the PCB, Fortunately the fuse had blown too.

AC400 Air Filter Safety Notice

In the last few days we have had a small number of AC400 Air Filters returned to us with significant overheating damage to the circuit boards inside. Whilst the boards are made of relevant certified flame retardant material, the damage is of a level where we feel we must recommend that all affected machines are issued with replacement boards and the machines are not used again until the boards are replaced.

Whilst we believe the overheating problem is restricted to machines manufactured up to June 2013 (up to serial number 20131416) this same basic board design was used in different generations until a completely new board was developed to incorporate a number of improvements. There are no known problems with the later board which is in current use. The format of current, unaffected serial numbers begin W14 with a further 6 digits and any serial numbers from W14001617 are unaffected.

If your machine is outside that range or if you cannot find your serial number you should unplug and cease to use the machine until you can contact us and we can arrange the necessary board replacement. If you are in any doubt as to whether your machine is affected or not we recommend you also unplug the machine and cease to use it until you have contacted us.

We are now making replacement boards but these will not be ready or in our stock until  week commencing 5th January so we apologise for the inconvenience this will cause. We can assure you we are doing everything we can to make the necessary parts and offer a solution as quickly as possible but felt it was important to raise our concerns over the possible safety issue immediately.

If you think you are affected or have any concerns please contact us via the following means;

LN Brian Boggs Spokeshave

This simply is the best spokeshave I've ever had. The Lee Valley and UK Clifton ones I also have are a joint close second (just a hair away from the Boggs) distantly followed by Stanley spokeshaves of which the modern versions quite frankly are not worth the metal they are cast from nowadays.
