2 humming baseboard heaters, 2 mute ones
:o
Hello there. This is my first question ever at this site. My question concerns the new baseboard heaters my husband and I had installed in our great room. The heaters on the South wall are working (and humming - which is a sound I didn't notice before), the heaters on the North wall are completely cold. The two heaters on the back wall are operated by separate thermostats, which I've tried turning all the way down then all the way up, off and on - everything. The two heaters on the front (South) wall are operated on the same thermostat. The weather has changed in the past few days - it has gotten extremely cold - could the cold temp have knocked out my heaters? What's going on?
