We have an old Danfoss 4033 timer that controls when our boiler turns on and off and the timer bit has just stopped turning by itself, so we’re no longer able to programme it to come on. (Although the boiler still works fine if we turn it on manually via the on/off switches of the Danfoss?
Is there anything worth trying to fix this or is a replacement the only option?
