Hello garagerob Thanks for your post - I don't think so - there is nothing wired/attached to the flue that I can see (hope I'm not being a bit simple!) I suppose that it could be something to do with a backdraught, but we've been living with the boiler for 5 years, and it's never done this...

Hello all I have an aging Potterton Kingfisher MF 60 (11 yrs old) which is having problems heating. For no immediately apparent reason, we find that the rooms are getting a bit cold/cold or tepid water in the tap, then check the boiler panel and find that the flame indicator light is out. We...

nuff said! :lol:

You're right of course, I'll put it down to experience, and next time, I'll post here first! Brian P.S. any of you cover the High Wycombe area? :wink:

At the risk of giving myself a stress related coronary, I'm considering persuing this whole issue with Corgi (as the engineer concerned is Corgi registered) or some official body. Is it just me that attracts poor workmen? Would anyone who has been following the course of events care to...

Hello Tony Great news - I've fixed it! The potentiometer was functioning correctly, so I replaced the PCB, and that was that! nice and warm, but definitely not boiling! On further inspection, when I removed the plastic casing from the PCB, one of the two relays is clearly blackened...

Hello Tony No need to apologise for the paste not working, this was a best case scenario, and most definitely worth pursuing... never mind. Can I check the Pot reliably with a simple multimeter, ie checking the resistance from one end of the scale to the other. If so, what should I look...

Hello Tony We've got rid of the engineer, who turned up, told us that the thermistor (which he had already replaced) was faulty, and that we would have to wait till next week before he could come back and fit another (we've been suffering from this problem for six weeks already since we first...

Hello Tony, I have just removed the front cover of the boiler and removed the thermistor to check, and ....... guess what..... not even the faintest smear of thermal paste on the new thermistor! The engineer is already booked in for tomorrow, so I'll leave a note suggesting that this should...

Hello Tony This is really interesting. The old thermistor had some white paste left on it, but from what you have said, it may well have been too little to be effective, and so it also follows that the old thermistor might still have been working if some more paste been applied. I'm going to...

Hello Baxpoti Thanks for your advice. Yes, the thermistor has been changed, I'll certainly suggest to the engineer that the the pot is a possible candidate for replacement, before he fits a new PCB, although from your post, it would seem that the PCB is now most likely to be at fault! Brian

Hello Tony Is the NTC sensor the Thermistor? if so, this was replaced by the engineer on the first visit. I looked at the old thermistor and tried to check it out (no conclusion - not really sure what to look for on the multimeter) it did have some thermal paste around it, I would assume that...

Hello Tony Thanks for replying I have checked, and the boiler is the MF CF 60, and is actually 9 years old this month - I found the receipt. I don't know what chemicals were used in the flush as I wasn't present when it was done, so unfortunately I can't throw any further light on that...

Potterton Kingfisher floor standing boiler - about 8 years old Gravity HW pumped CH All rads have Thermostatic Valves Do not have a central room thermostat System working happily for the four years that we have been in the house. All rads bar one, and all rad thermostats replaced four years...
