Hello, my son has a RSA85 boiler for heating baseboard only. The controls are L8148A aquastat and R4184D1027 Primary control both are Honeywell. When the thermostat calls for heat the burner does not attemt to fire up.The contact in the aquastat pulled in but no attempt to start I checked the input to the aquastat for correct voltage and it was 120vac . I then checked the output and had no voltage, I checked at the red and white wire that feeds to the primary control. I'am not sure if I measured at the correct place. I opened the transformer and checked for 5k at each coil and had none . This is a 2 zone and from the aquastat I could see a green lightand a red light on trying to call for heat, lowering the thermostat below room temp shut off the red light. Is the 120VAC taken from the Aquastar and sent to the primary ? Getting cold in N.H need help soon. Thanks, Rickeyb

I have a Weil MClain EG75PI boiler (2 pipe radiators) and have been having heating issues the past few days. I beleive the boiler to be a 1988 vintage. This is in a 3,000 sf residential application. On the 1st floor appoximately 50 percent of a radiators leaves heat, the balance remain cool. On the second floor approximately 25 percent of the leaves heat. This is on all radiators. With the thermostat at 65, we maintain approximately 70 degress in the basement, 60 degrees on the first floor, 50 degrees on the second. The boiler fires and runs for approximately 1 minute before shutting down. It does have an intermittent option but burned longer in previous seasons. The pressure gauge typically reads 2 psi. From time to time, the boiler does not fire, only hearing the clicking of the ignitor. When this occurs, the gauge reads 10 psi. Once the pressure drops, the boiler fires and the radiators partially heat. I have not attempted to raise the thermostat to correct the problem as I assume this only burns fuel with no appreciable outcome. I remove sediment monthly (during season) and the water level is correct. I know little about boilers but am very mechanical. Before you say call a professional, I would have to ask if there are any in my area. I have called several, and between missed appointments and "oh, this is steam" I have been several days now. I am running out of vendor options no longer have patience for them. Thank you in advance for your help.
