I called Sears and the part# 387.92551 has been d[FONT=Arial][COLOR=#000000]iscontinued. Is there another thermostat control relay made by a different manufactor that would work?

A thermostat control relay? Either a fan relay or control relay. Assuming you are correct about being a “Boiler” eliminates fan relay. So any relay with a 24volt coil will work. A relay is just a switch. :slight_smile:
