My central heating will not come on or go off with the programmer. Firstly it would not turn off and the house was 30 degrees. Now it won't go on and it is freezing! The heating engineer fitted a new pump two days ago. What do I do? Please help.
My boiler will not come on with thermostat.

I had this problem recently, hold old is your boiler? I had to have the programmer changed which unfortunately is an expensive part (£150 plus labour £200)
You need to get your heating "engineer" back. The programmer times everything to come on or off - it also controls other critical parts of the system like diverter valves. Not enough information from you to hazard a guess. Combination boiler, system boiler??
David that sounds horribly expensive. If it was a separate i.e. not built into boiler, programmer, then £50 thereabouts for a programmer and if it's on a BG standard backplate, 15-minutes to change, 30 at most.

I have read that the recent snow is getting into these boilers and causing them to fail. Read this thread from another forum. I'm not familiar with your type of boilers.
