People also ask
A failed control transformer takes the thermostat, the zone valves and the relays with it. The boiler itself may be perfectly healthy.
Age, heat and a short somewhere on the low-voltage side. A repeated failure usually means the short is still there.
The part is small, though the real work is finding why it failed. A technician traces the low-voltage circuit rather than just swapping it.
It does. With 81 percent of the housing predating 1980 here and around Altona, plenty of low-voltage wiring is decades past its best.
