Baseboard heater ticking 24/7 (and it’s off!)

sbecke3

Hi, I moved about 6 months ago and am now in an apartment that has baseboard heaters. Past week I’ve been having the issue that there is a constant, rapid ticking noise coming from the heaters, even though it’s summer here and I have set the thermostat to the lowest setting so the heater won’t turn on (which it had been doing at night for whatever reason, which is another problem in itself).
Anyways I have absolutely no idea why it is ticking and the usual “metal expands and contracts with the heat” doesn’t apply here. It’s driving me nuts and I can’t fall asleep/wake up constantly as it seems to be louder in my bedroom. 

I’d appreciate any help if there’s any fix I can try myself before having to call someone (can’t currently get a hold of my landlord either).
thanks

It could be another Appartment pulling up hot water and amplifying over to the baseboard piping ....

Electric or Hot water baseboard?

neilc

can you feel the baseboard warm or hot either while it's ticking, or if it's quiet ?
is there warmth or heat there?
just the one baseboard or all or others of them ?

@kcopp It’s a hot water baseboard. @neilc They’re all cold to the touch when ticking. So there’s one wall in the living room and one wall in the bedroom- I hear the bedroom the loudest, but the living room ones also tick as well just not as audible during the day due to background noises. If I’m not mistaken they’re all connected as well being hot water heaters. There’s an automatic bleeder valve, I had wanted to bleed them but seems like that’s taken care of which is the limit of my expertise...

Pipes connected in loops (or circuits) are resonant. If something is "ticking" anywhere on the system, the noise will be transmitted throughout the loop(s). First place to check is in the boiler room. Then...anywhere else the pipes run.

My guess is that there is a flow check that is not seating on the boiler piping. Im guessing that the boiler is also used to make domestic hot water. So the water in the boiler is hot and some hot boiler water trickles out into the system causing the expansion noises.

or it could be the domestic hot moving around and touching and transmitting
