Hello, I have a Drayton RF2 digistat connected to a Baxi Combi 105 HE. I have had 5 years without a problem but for some reason now the bolier seems to not be "hearing" the receiver. The thermostat and receiver appear to be working fine with flame signal and LEDs all in working order however every couple of nights, the heating won't see the little green light of the receiver and won't switch on. I've been having to switch off at the wall to get the boiler to fire up. It will then work fine for a couple of days before it happens again...

Any suggestions much appreciated!

look on ebay, I sell the capacitor which will fix this issue, if you search for "draton scr repair", you will find me, I am the ebay seller 'bearsy72' , for just a few quid i can send you the part you need and full installation instructions / pictures, should only take 15mins to change.

you will need a soldering iron to complete the fix, if you dont have one then send the scr to me and i can change it for you
