## Questions & Answers

**Q: I want to replace my existing boiler, a potterton suprima 40l. which potterton model would  this now be? what might be a better choice?**
A: Hi, please contact Hanicks Heating & Spares TECH TEAM on 01302 279234 with your boiler GC No. to hand.

**Q: Hi.  i was wondering if this is the replacement pcb made by siemens?  i heard there were a lot of problems with the original pcb's.**
A: Hi
This is the upgraded model as it had issues about 18years ago so this is the current model and only model of pcb for the suprima 30-100 range.

Thank you abs I hope this helps

**Q: In the case of Suprima's 100s does the fan part number of 5000860 relate to the new fan required or is it the number of the old one to be replaced ?**
A: I am no expert but the number 5000860 is the replacement potterton fan assembly - In my opinion the part number for the original and replacement item are the same

**Q: I noticed the connector to the gas valve doesn't have the white link wire from pins 2 to 4 that our old pcb uses.  does this link need to be added?**
A: It was a while ago but I do not recall needing any extra wires. The instructions were clear and everything worked perfectly. Not had an issue with my Potterton Suprima 40 since fitting this control unit. Hope this helps. Regards Gary

## Customer Reviews

### ⭐ Defective item
*by A***A on 27 March 2022*

After being correctly fitted by an experienced engineer, the problematic red flashing light continued so the PCB was returned as defective. Unfortunately, without an actual Gas Engineer report to prove that it's defective, this seller will only refund 50% of the purchase price. Better to just book a gas engineer from the start and not buy the PCB yourself. Look the company up on trust pilot and see the negative reviews for yourself.

### ⭐⭐⭐⭐⭐ Perfect replacement for original PCB
*by J***N on 24 January 2014*

I bought this for the same reasons that everyone does: the original PCB that came with the Potterton Suprima 60L boiler was rubbish, and after a while suffers from heat damage / dry joints etc. and ends up constantly getting itself into a lock-out state where it needs resetting. The various options are basically:- to repair the PCB (i.e. get your soldering iron out and start fixing the dry joints)- to replace just the PCB with a reconditioned one (which may keep it going for another couple of years before it goes again)- to replace the whole control unit with this item - a brand new PCB kitIn turns out that our PCB had already been replaced at least twice before, so I decided that rather than simply delay things with a replacement PCB, I bought this kit instead. You get the entire control mechanism (temperature knob, led and all), and most importantly: the entire PCB is actually enclosed to shield it from the heat of the boiler.The whole unit comes in a box with the kit, together with new electrode and earth wires (for both 30-80, and 100 models). This is important because you'll want to replace the electrode wire as well, when you replace the PCB.I got a proper heating engineer, who knew exactly what he was doing, to replace the unit itself (and I would strongly recommend this option rather than doing it yourself, unless you have experience with these type of boilers), and he managed it in his personal best time of 1 hour. Job done. £155 + £48 fitting = £203 ... far cheaper than I was getting quoted by other companies that supply the unit as well.The unit has been fitted now for a couple of months and is working perfectly.

### ⭐⭐⭐⭐ Easy to fit
*by P***S on 1 July 2016*

Got this to replace the board only, everything else was working. Easy to fit, instructions are good. after fitting it the boiler started working again.
