Customer Question
I have a White Rodgers...
I have a White Rodgers 842a-16 control unit that is giving me some problems. It works fine during the day, but when I get up in the morning,I have to "tap" the relay to get the pump to start. The zone valves are calling for heat, but the pump does not start. I found an 842A and a 842a-1 online. are these acceptable replacements?
