Hum from baseboard even when it's off
There is a humming sound coming from 1 of the baseboards even when it is not heating. I turned the breaker off and the sound stops. The thermostat controlling this is a 12v.
Do you think the baseboard just needs replacing or is it something to do with the remote system.
I'm not even sure why it runs on a remote system as it's only 1 baseboard controlled by the thermostat.

Not all transformers hum. Most are quiet like they were designed to be but sometimes with age and heat.... the metal laminations inside the transformer come loose and vibrate.

If you hear it in the baseboard then it's probably inside. There is usually a removable cover over each end of the unit to access controls and wiring. Turn power off before removing the covers.

Seems like a strange setup. The breaker (2 pole ie double lever) runs 3 baseboards.
1 x 1000W with 22v A-c (not sure why it's 22 and not 24)
1 x 750W also with 22v ac
1 x 500W 240 ac so thermostat controls without a relay?
I don't fully understand the 2 22v a-c connections. Surely they must go via a relay /remote box but why have 2 separate remotes if they are each controlling 1 heater only?
