When switched on my immersion heater buzzes, it buzzes then stops and starts
again, it is heating all the time but something vibrates intermittently I
think it may be the thermostat vibrating in its tube , Any help appreciated
This may be the right thing to do. But if there is indeed arcing going
on (as has been suggested), then it should be corrected because it will
erode the terminal away. Have you tried switching it on with the cover
removed and having a look?
the cable insulation near the terminal, making it easier to spot with the
power off. If caught early enough it, can be repaired by snipping off the
melted section and renewing the connection, after first checking the
terminal screw and terminal are still in good condition. As usual. if in any
doubt, have it checked by a qualified electrician.
Turn off the power to the immersion heater and take off the cover to inspect
the cable terminal ends - I once had a buzzing similar to this in an
electric shower and ignored it to my cost.
The damn thing caught fire just as I was stepping into it one morning as the
result of a loose connection.
