My bedroom baseboard copper lines bang when the thermostat is satisfied, causing Honeywell V8043 motorized valve to close. I think the valve is closing too quickly as the base board hot water is still flowing through the system. The bedroom is the furtest loop in the ranch house. Besides changing to a Taco valve which closes slower is there another option. By the way the sys. pressure is 15 psi. thanks

Hi all. My old oil burner (Peerless) worked fine last winter, but when I went to turn it on the other day, it didn't produce any heat. Last spring, I'd turned it off at the Emergency power switch (the house is vacant). When I turned the power back on the other day, nothing happened. After hitting the Reset button, it fired up after a few seconds, and I let it run for over an hour. But everything stayed ice-cold, even the furnace itself. The blower motor (or circulating pump, I'm not sure which, or both) ran the whole time -- sounded like the usual old furnace sounds, but with no heat being produced. Any suggestions on where to look to begin diagnosing the problem? Tank has plenty of fuel. It's a cast-iron hot water radiator system. I opened the transformer and it looks a little corroded around the electrodes. We had some moist air in the basement this summer... Might that have made for some bad connections? Would those electrodes explain the blower running but no heat? Thanks for any thoughts on the likely culprits! John
