Re: Boiler making a buzzing sound

This is an older thread now but I wanted to add my two cents after experiencing this. I had dirty contacts on the RA832A as well. The dollar bill trick did not work for me (perhaps too much deposition) however a five dollar contact burnishing tool from my local electrical supply store (can be found cheaper on the web) soon solved the issue. I could see residue on the burnishing tool after only a few seconds of use.

I hope this helps.

Re: Boiler making a buzzing sound

Hi I just found this thead. I have the same buzzing RA832A relay! Here's my video: https://youtu.be/7P6JDP2rkps

I'm able to stop the buzzing temporarily by jostling the device, but it always comes back. Should I try cleaning the connections also? Just get a newer model?

Have a Weill McLean steam boiler, with a hot water loop to kitchen kicker heaters. The relay runs the kitchen thermostat / pump. Thanks!
