Hello. I have central heating system which features a Honeywell V4043H 1106 motorised valve. There's little microswitch in this device which switches power to the boilers and pump when the valve is opened.
This microswitch has broken (using its built-in December alert mechanism). I've used a jumper on the connection box so we are not freezing, but I suppose this is not a good long term solution.
I know I can replace the entire powerhead with a 40003916. But this costs about £40. Does anyone have any idea if I can just replace the microswitch to save about £35. How can I choose the correct microswitch?
Many thanks
