Central Heating stopped working

[Darkwing]

Hi All

My boiler is fine - i get hot water no issue.

The problem is that my central heating isn't coming on.

I have a Drayton SM1 control and although it makes the "clock sound" moving the switches on the control does nothing. I can not get the red light to show up at all.

Is this likely to be an issue with the control being faulty or something else in the system?

Thanks for any advice.

Welcome to the forum. Need a bit more detail or better still pictures of pump and controls.

If the time clock has a red light not working, then probably is the clock that is faulty. Needs a simple check to see if power is going to boiler.
Some systems have motorised valves and can be wired that the power goes from the motorised valve when it opens to the boiler and it is possible for it to be faulty.

Welcome to the forum Darkwing, if it is not something you can diy then post your postcode and perhaps a member local to you could help.

It's annoying as was only serviced a month or two back! I believe it's covered under my house insurance so I could give them a call but if it's simply a case of replacing the unit then it's pretty straight forward.

Sorry that's me!

Got the same boiler. Presumably your timeswitch is wired across the room stat terminals? Do you have a room stat in line as well or just using the timeswitch?
If you're competent with a screwdriver you could move the red wire on terminal 5 to the black wire on terminal 3. If the heating comes on it's a fault with the timeswitch contacts. If it doesn't, there's a break or something else in the line.

Thanks I'll give that a go and see what happens. The themostat is in the hallway, that's not lighting up either.

I've just done this - the heating is back! (well till i move it back).

Does this just sound like the unit is broken?

Get yourself a more up to date timer, should be a simple swap.
