Review on 💨 Reliable Emerson 90-290Q Fan Relay SPST for Efficient Air Control by Christopher Kumar

I used this along with a 24v power supply to add a nest thermostat to my old millivolt gas fire. , reliable and economical operation. "However, when the system turns on, I hear a distinct click (which is normal) and then a LOUD CONSTANT BUM heard from the next room. I mean, technically she does the fireplace, so he gets some stars for that. But I can't live with this constant buzz all winter! Will be back if I don't get a replacement I've read in some other reviews that some broken blocks and spares seem to have been silent.
